Introduction — Why Your Native Language Shapes Your Thinking

Have you ever noticed how your thoughts flow effortlessly when you use your Native Language? Whether you speak Tamil, Hindi, Bengali, Malayalam, Telugu, Kannada, Marathi, or any regional language — your brain feels “at home” in it.

Modern research in linguistics and cognitive psychology reveals a profound truth:

👉 The language you first learned as a child influences how you think, feel, reason, learn, and create.

Your native language thinking forms the foundation of your identity and mental processes. Even if you are fluent in English, your brain still relies on your mother tongue for clarity, faster processing, and emotional depth.

Let’s explore why your native language is not just a means of communication — it’s a powerful cognitive tool.


Cognitive Advantages of Thinking in Your Native Language
Better Comprehension and Clarity

When you think in your native language, your brain does not waste energy translating ideas.
The result?

  • Faster understanding
  • Clearer mental processing
  • Reduced confusion
  • Sharper focus

This is why students understand concepts better when initially explained in their mother tongue.

 
Faster Problem-Solving

Problem-solving requires intuition, logic, and quick thinking. These cognitive processes are strongest in your native language because your brain has spent years forming associations in it.

Daily decisions like budgeting, planning, and evaluating choices naturally happen in your mother tongue — because it boosts mental efficiency.

 

Stronger Memory Retention

Your early memories, emotions, and learning experiences are deeply connected to your native language.

This makes it easier to:

  • Remember details
  • Recall facts
  • Understand complex ideas

Studies prove that people retain information longer when learned in their mother tongue due to stronger neural pathways.

 

Mother Tongue Cognition Improves Decision Making

When making important decisions — financial, personal, relational — most people unconsciously “switch back” to their native language.

Why?
Because the mother tongue provides:

  • Emotional balance
  • Cognitive clarity
  • Realistic reasoning

It helps you think slowly, clearly, and more confidently.


Power of thinking in native language



 

Emotional Connection — Why Your First Language Feels Natural
Authenticity of Thought

Your native language shapes your internal world.
When you think in your mother tongue:

  • Ideas feel genuine
  • Emotions feel natural
  • Thoughts flow effortlessly

The expression isn’t forced or filtered.

 

Confidence Boost & Reduced Self-Doubt

Thinking in a foreign language can create:

  • Hesitation
  • Fear of mistakes
  • Slower thought patterns

Your native language removes this mental pressure, leading to higher confidence and better communication.

 
Emotional Expression and Cultural Context

The way you express love, anger, happiness, or sadness is deeply tied to your first language.

Even bilingual people admit that certain feelings “sound different” in their mother tongue because emotional memory is encoded in it.

 

Creativity and Innovation Improve in Your Native Language
Unrestricted Imagination

Creativity requires a free mental flow.
But when thinking in a foreign language, the brain often pauses to:

  • Translate
  • Correct
  • Filter words

This slows down imagination.

In contrast, the native language removes all mental blocks — resulting in:

  • Better storytelling
  • Original ideas
  • Higher innovation
  • Authentic expression

Cultural Richness as a Creative Resource

Your mother tongue carries centuries of:

  • Folklore
  • Idioms
  • Cultural wisdom
  • Metaphorical richness

These elements expand your creative potential and allow deeper, more meaningful ideas.

 
Case Studies & Real Examples

  • APJ Abdul Kalam ideated in Tamil before translating into English.
  • Rabindranath Tagore created masterpieces rooted in Bengali thought.
  • Sundar Pichai often shares how his Tamil upbringing strengthened his problem-solving abilities.

Creativity becomes powerful when grounded in your native-language thinking.

 

Thinking in Your Native Language Enhances Learning & Productivity
Better Learning Outcomes

Students understand lessons faster when explained in their mother tongue. That’s why:

  • Bilingual education improves mastery
  • Regional-language explanations improve clarity
  • Foundation learning works best in native languages

Efficiency in Work

When it comes to workplace decision-making:

  • Planning
  • Calculating
  • Problem-solving
  • Organizing

…thinking in your native language leads to faster and more accurate results.

Even if your job requires English, internal thinking is most effective in the mother tongue.

Why Even Multilingual Experts Think in Their Native Language First

Most bilinguals think in their first language and speak in their second.
This is natural because the native language is:

  • Faster
  • Clearer
  • Emotionally stable
  • More intuitive

Your first language remains the core engine of your cognitive processes.


Bilingualism: When and How to Switch Between Languages
Strategic Language Switching

Use your native language for:

  • Deep thinking
  • Problem-solving
  • Emotional decisions
  • Creativity

Use English or another language for:

  • Global communication
  • Technical terminology
  • Professional presentations

This “dual-mode thinking” gives you the best of both worlds.


Bilingual Creativity & Mental Flexibility

Bilingual individuals have higher mental flexibility.
Switching languages boosts:

  • Innovation
  • Critical thinking
  • Social intelligence
  • Cultural awareness

It also enhances adaptability and communication skills.

How to Strengthen Native Language Thinking
Daily Habits

  • Journal in your mother tongue
  • Practice mental math in your native language
  • Speak with family & elders
  • Think aloud using your native language

Thinking in your native language is one of the most powerful tools you possess. It boosts:

  • Clarity
  • Creativity
  • Memory
  • Emotional intelligence
  • Learning efficiency
  • Productivity

Your mother tongue is not an obstacle — it is an intellectual asset.
Embrace it, nurture it, and let it guide your thoughts with confidence and clarity.

Cognitive, Emotional, and Academic Benefits of Mastering One's Mother Tongue

In today's globalized world, being multilingual is a powerful asset. But before one can fluently speak many languages, it's essential to build a strong foundation in the first language—your mother tongue. Whether it’s Tamil, Hindi, Telugu, Malayalam, or Kannada, first language proficiency unlocks lifelong advantages.  [UNESCO, 2008].

At Maadhyamik, we support regional language learning through intuitive keyboard tools and typing solutions that help learners stay connected to their roots.


Cognitive Benefits of Mastering the First Language

Language Enhances Brain Development

First Language Proficiency


Children who become fluent in their mother tongue develop:

First Language Connects Us Emotionally

Our mother tongue is how we first express love, frustration, dreams, and identity. Children feel:

  • A stronger sense of belonging
  • Increased confidence in expressing ideas
  • Emotional comfort in familiar sounds and words

Encouraging your child to speak their first language affirms their cultural identity and improves self-esteem [Skutnabb-Kangas, 2000].


Academic Success through Mother Tongue Instruction

Learning Is Easier in the Language You Understand


Studies show that early education in a child’s mother tongue leads to:

  • Better classroom engagement
  • Higher literacy and comprehension
  • Long-term academic achievement

Children understand concepts faster when lessons are delivered in a language they deeply understand [UNESCO, 2016; Government of India NEP 2020].


That’s why providing students with tools to read and write in their mother tongue is so important—it supports these academic outcomes in real, everyday practice.

Explore our Phonetic Hindi Keyboard to help support Hindi learning in schools and at home.


The Multilingual Advantage Begins with One Strong Language

First Language Skills Help You Learn Others


Multilingualism is easier to achieve when the first language is strong. Skills such as grammar, sentence structure, and vocabulary transfer across languages.

Mastery in your mother tongue helps:

  • Learn English or other global languages faster
  • Think more clearly

Insights from Education Research and Real-World Examples

In a rapidly globalizing world, raising multilingual children is a growing priority for parents and educators. But while many focus on learning English or other global languages early, research shows that the best way to build multilingual fluency is by first developing strong literacy skills in the mother tongue [UNESCO, 2016; Government of India NEP 2020].

Whether it's Tamil, Telugu, Hindi, Kannada, or Malayalam, early reading and writing in a child’s native language unlocks long-term success in learning additional languages—both academically and socially.



Why the Mother Tongue Comes First


Children learn best in a language they understand deeply. When literacy begins in the mother tongue, it:

  • Builds a strong cognitive foundation
  • Enhances concept clarity and critical thinking
  • Reduces confusion when new languages are introduced

[Cummins, 1979; Heugh, 2011]


Multilingual Learning



Brain Science Supports This

Language pathways in the brain develop rapidly in early childhood. Studies show that when children first learn to read and write in their native language, it activates areas in the brain that later support second-language learning [Thomas & Collier, 2002].

Educational Research Backs It Up

According to UNESCO and global literacy studies:

  • Bilingual children who learn to read in their first language perform better overall than those who start with a second language.
  • Early literacy in the mother tongue leads to stronger reading comprehension and vocabulary in both the first and second languages.

Real-World Example:

In Andhra Pradesh, students who began reading in Telugu before being introduced to English showed greater fluency and confidence in both languages compared to those who started directly in English [Heugh, 2011].

Tip: Support early literacy with our Tamil Typing Keyboard and give children an easy way to learn in their own language.

Classroom Success Stories

India’s Multilingual Schools


Many Indian schools now integrate mother tongue literacy in early grades, especially in Tamil Nadu, Karnataka, and Kerala. These programs show:

  • Increased student engagement
  • Lower dropout rates
  • Improved multilingual performance in later years

[Government of India NEP 2020]

Teaching children in their first language first is not a delay—it’s an acceleration strategy.

 Try our Multi-Language Keyboard to help your child practice early literacy in their own script—be it Tamil, Hindi, or Telugu.


Multilingualism is Built on a Strong First Language


When children become literate in their mother tongue, they don’t just become fluent in one language—they build a bridge to many.

Benefits:

  • Grammar awareness transfers across languages
  • Reading strategies develop earlier
  • Confidence in one language spills into others

[Cummins, 2001; Heugh, 2011]

It’s like learning to ride a bicycle once—you can adapt to different terrains, but the balance comes from that first experience.


Frequently Asked Questions (FAQ)

Why is early literacy in the mother tongue important?

Because it strengthens core reading and thinking skills that help children learn second and third languages more easily [UNESCO, 2016].

Will learning in the native language delay English fluency?

No. In fact, starting in the mother tongue leads to better English learning later because of stronger foundational literacy [Cummins, 2001].

What age should children start reading in their first language?

As early as 3–5 years old. Reading books, stories, and typing in their native script builds early literacy [Thomas & Collier, 2002].

How can I help my child type in their mother tongue?

Use phonetic or visual keyboards like:

  • Tamil Keyboard Online
  • Hindi Typing Keyboard
  • Telugu Keyboard Download

What if the school teaches only in English?

Support your child at home with reading and writing activities in your native language. Multilingual skills begin with parental involvement [Government of India NEP 2020].

Introduction: Why Native Language Learning Matters Today

Native Language Learning is more important today than ever before. As children and adults navigate a globalized world, the mother tongue serves as a foundational connection to culture, identity, and cognitive growth. Research shows that learning in one’s first language improves comprehension, memory, and long-term educational outcomes. Further, the native language helps the speakers to understand and stay connected with their own culture and heritage.

Technology has transformed how we teach and learn languages. From mobile apps to digital storytelling, today’s tools make native language education more interactive, engaging, and accessible than traditional books or classroom-only models.

 

The Role of Technology in Native Language Learning

Anytime, Anywhere Access to Learning

One of the biggest advantages of technology for native language learning is flexibility. Learners can practice vocabulary, grammar, and pronunciation anytime—whether at home, on the bus, or during school breaks. This is especially helpful in regions where physical books or libraries may be limited.

Self-Paced Learning with Unlimited Repetition

Digital tools allow repeated practice, which is essential for mastering language fundamentals. Learners can:

  • Replay audio lessons
  • Revisit vocabulary lists/ challenges/ puzzles
  • Repeat grammar exercises
  • Practice pronunciation with instant feedback

This promotes mastery at one’s own pace instead of being restricted by a classroom schedule.

Gamification & Immersive Learning

Colourful visuals, interactive quizzes, self-exploratory activities and reward points for learning etc. keep learners engaged and motivated. Gamification has been proven to improve both interest retention and sustained learning participation. Immersive elements—like AR flashcards or voice-based interactions/ conversations—help learners experience the language in realistic contexts.

 

Effective Digital Tools for Mother Tongue Education

Mobile Apps for Language Learning

Mobile apps offer bite-sized lessons ideal for children and adults. Common features include:

  • Vocabulary drills
  • Pronunciation guides

As part of our efforts to build optimized, intuitive keyboard layouts for Indian languages, we’ve conducted detailed character frequency analysis for Malayalam. This post presents our findings—showing which characters, vowels, and consonants occur most frequently in real-world usage based on large Malayalam dataset—and briefly discusses how this data influenced the keyboard design.


For an explanation of our overall keyboard design methodology, including the rationale behind layout decisions, please refer to our Tamil keyboard design post: Designing a New Input Method for Tamil


Dataset Used for Frequency Analysis

To ensure broad linguistic coverage and reliability, we used Malayalam corpora by combining text data from multiple sources, including:

  • IndicCorp
  • Swathantra Malayalam corpus
  • Wikipedia Malayalam corpus
  • News articles, blogs, etc.

Here is the high-level statistics of the corpora used in our analysis:

  • Total words: 1.699 billion
  • Unique words: 25.345 million

This large and diverse dataset gives us a realistic view of character usage in modern written Malayalam.


Overall Character Frequency Heatmap

This heatmap illustrates the relative frequency of Malayalam characters based on their usage across a dataset. The top row represents the frequency of vowels, while the last column shows the frequency of pure consonants. The remaining cells capture the usage of consonant-vowel combinations. Color intensity indicates frequency, with darker shades signifying higher usage and lighter shades indicating lower frequency.

Characters such as അ (a), മ (ma), ന (na), and ക (ka) appear with consistently dark shades, across their rows, indicating they are among the most frequently used. These are foundational phonemes in Malayalam and are common across both spoken and written forms. Characters like പ (pa), ത (tha), and ല (la) show moderate frequency across their respective row, suggesting they are contextually important but not as dominant. Their usage may vary depending on the domain (e.g., literary vs. conversational text).


Vowel Frequency Heatmap

To gain deeper insights, we examined the frequency of Malayalam vowels both in their standalone and combined consonant-vowel forms. This analysis was derived by summing the columns of our overall character frequency chart, offering a clear view of vowel usage patterns. The results are visualized in the chart below.

Malayalam has a rich vowel system, but a handful of vowels—especially അ, ഇ, ഉ, and എ—occur most frequently. Further as expected, the shorter vowels are more frequent than their longer versions. Note that these counts include the usage frequency of vowels as well as the vowel sign glyphs in their consonant vowel forms. The last cell in the heat map actually refers to the frequency of the Chandrakala (Virama) character.


Consonant Frequency Heatmap

In addition to vowels, we also analyzed the frequency of Malayalam consonants. This was done by summing the rows of the overall character frequency chart, which highlights how often each consonant appears across different vowel combinations. The resulting data provides a clearer picture of consonant usage patterns in the language.

Among consonants, we can see a clear dominance of ക്, ന്, ത് യ്, and ര്. These findings informed our decisions in distributing consonants across the keyboard layout for minimizing the finger movements during typing. In line with the InScript keyboard layout convention, each aspirated consonant was assigned to a specific key, while its corresponding unaspirated counterpart was placed in the corresponding shift position.


Chillaksharam Frequency Heatmap

We also analyzed the frequency of chillaksharam (ചില്ലക്ഷരം)—the special consonant forms used at the end of syllables in Malayalam, such as ൽ, ൻ, ൾ, and ൿ. These characters are essential for accurate representation of the language and are frequently used in written text.

Frequency of ML chillaksharams in our dataset

Following our keyboard design principles, each chillaksharam is placed in the Alt + Shift position of the corresponding base consonant key. For example, the character ൿ is mapped to the Alt + Shift position of the ക് key. Since mobile keyboards typically do not include an Alt key, these chillaksharam characters are made accessible through long-press gestures on their respective base keys. So, long-pressing the ക് key on a mobile keyboard would reveal ൿ, ensuring consistency and ease of access across platforms.


Impact on Keyboard Layout Design

Whether you're using a Malayalam phonetic keyboard or a standard Malayalam keyboard, these insights can guide better input method development. As part of our design, we excluded individual vowel signs and instead generate them dynamically from consonant-vowel combinations. This approach reduces complexity and prevents invalid character sequences.


These frequency trends helps in designing the layout for our Malayalam keyboard. High-frequency characters were assigned to primary home row or easy index finger positions, ensuring reduced typing effort and faster input for users. Low-frequency characters were positioned in secondary or long-press locations. As part of our design, we excluded individual vowel signs and instead generate them dynamically from consonant-vowel combinations. This approach reduces complexity and prevents invalid character sequences.

As part of our broader initiative to develop optimized and user-friendly keyboard layouts for various Indic languages, this blog post focusses on our efforts in Hindi. We start with a detailed character frequency analysis for Hindi. Using large-scale monolingual Hindi datasets collected from the web, this study focused on understanding the usage patterns of Hindi characters in real-world text. The insights gained from this analysis played a key role in designing a more intuitive and efficient Hindi keyboard layout, aimed at enhancing typing speed and improving text prediction capabilities on mobile platforms.


Dataset Overview

We collected multiple monolingual Hindi datasets from the web, including the following key corpora.

  • IITB Hindi Monolingual corpus
  • IndicCorp
  • Leipzig Hindi Datasets
  • Lindat HindEnCorp 0.5
  • IndicNLP News Articles
  • Samanantar v0.3 (En-Indic; Indic-Indic)
  • Classificataion Datasets (iNLTK, BBC Articles etc.)

After thorough data pre-processing and noise removal, the final dataset comprised approximately 8.92 billion total tokens and around 13.1 million unique tokens. Our character frequency analysis was conducted on this extensive and diverse dataset, providing a robust statistical foundation for our findings.


Detailed Character Frequency Analysis

We began by analyzing the frequency of all the characters in the Hindi alphabet, depicted as a heatmap as a matrix with vowels and consonants shown along the row and column axes respectively. The most frequenct characters are marged in darker colours, while the less frequent ones in progressively lighter shades.

Heatmap showing the frequency distribution of all Hindi characters, arranged in a matrix with vowels as rows and consonants as columns. The color intensity represents the frequency of each consonant-vowel combination, highlighting commonly used Consonant-vowel (CV) pairs.

Interestingly, unlike in Dravidian languages or Marathi, Hindi displayed a unique pattern: the vowel ए appeared more frequently than the alphabet-initial vowel अ in its standalone form. However, when it came to consonant-vowel combinations, the अ vowel was more dominant than ए, indicating a distinct usage trend in Hindi text.


Vowel Frequency Analysis

We then analyzed the frequency of Hindi vowels, both in their standalone form (e.g., अ, इ, उ) and when combined with consonants (e.g., का, कि, कु). This was done by summing the columns of our overall character frequency chart. The resulting data highlights which vowel sounds are most commonly used in Hindi text, offering valuable insights for layout prioritization and predictive typing.

Bar chart-style heatmap displaying the total frequency of each Hindi vowel, calculated by summing across all consonants in each column. This visualization emphasizes the relative usage of standalone and combined vowel forms.

The top three most frequently used vowels in consonant-vowel (CV) combinations are अ (a), आ (aa), and ए (e). These vowels form the core of Hindi phonetic structure and are heavily represented across the language. The virama (aka halant) sign (्), used to suppress the inherent vowel and form conjunct consonants, appears 3082.36M times (last cell in the heatmap) —making it the fourth most frequently used glyph in the dataset. This is a notable finding, especially when compared to Dravidian languages, where the virama is often as dominant as the अ CV form. In Hindi, while still highly frequent, it plays a slightly less central role in character composition. Vowels like इ (i), ई (ii), ओ (o), and अं (aṃ) also show significant usage, each contributing meaningfully to the overall character distribution. Characters such as ऋ (vR), औ (au), अः (aḥ), and अँ (aṅ) appear far less frequently, reflecting their more limited use in modern Hindi text.


Based on this analysis and also following our earlier convention for other languages, we laid out the अ, इ, उ, ए, and ओ short vowels in left-hand position of the home row and the long vowels (if applicable) in their corresponding shift key positions. This makes it easier for users to type the most frequent vowels with their dominant fingers.


Consonant Frequency Analysis

Next, we turned our attention to consonants. By summing the rows of the character frequency chart, we identified how frequently each consonant appears across different vowel combinations. This row-wise analysis reveals the most commonly used consonants in Hindi, which is crucial for optimizing key placement and improving typing efficiency.

Bar chart-style heatmap showing the total frequency of each Hindi consonant, derived by summing across all vowel combinations in each row. The chart highlights the most frequently used consonants in Hindi text.The consonants क् (k), र् (r), न् (n), ह् (h), and स् (S) top the frequency chart, with क being the most dominant at 4498.56 million occurrences. These high-frequency consonants are central to Hindi phonology and appear across a wide range of words and contexts. Characters like म् (m), द् (d), य् (y), ल् (l), and प् (p) also show significant usage, each exceeding 1000 million occurrences. These contribute to the core structure of Hindi vocabulary. Aspirated and retroflex consonants such as झ् (jh), ञ् (ny), ङ् (ng), and घ् (gh) appear far less frequently, with ङ् being the least used at just 0.31 million.


Nukta Usage in Hindi Orthography

The Nukta (or nuqta, '़') is a diacritic mark used in Hindi to represent phonemes that are not native to Indic languages but have been borrowed from Arabic, Persian, English, and other foreign sources. In standard Hindi, the use of the Nukta is restricted to a specific set of consonants—seven of which are widely accepted and standardized. Our analysis focuses on the frequency of these seven Nukta-modified characters, as visualized in the accompanying heatmap.

Heatmap showing the frequency of seven Hindi consonants modified with the Nukta diacritic. The heatmap uses a color gradient from light yellow (low frequency) to dark purple (high frequency) to represent usage intensity.

The heatmap reveals significant variation in the usage of these characters. Among them, 'ड़' (ṛa) is the most frequently used, appearing approximately 192.87 million times. This is followed by 'ढ़' (ṛha) with 55.47 million instances, and 'ज़' (za) with 30.09 million. Other characters such as 'फ़' (fa), 'ख़' (kha), 'क़' (qa), and 'ग़' (gha) show moderate to low usage, ranging between 6 and 13 million occurrences.


Importantly, Nukta characters do not combine with the virama and therefore do not form conjuncts. However, they can take vowel signs to form syllabic units, as seen in words like सड़क, पड़ा, खिलाड़ी, and जुड़े. Due to this behavior, unlike regular consonants, Nukta characters are represented in their full CV (consonant-vowel) form—typically the akāra form—in the Varta keyboard layout. To maintain intuitive typing, these characters are mapped to the same key positions as their base consonants, accessible via Alt + Shift on desktop keyboards or through long press options on mobile keyboards.


Special Characters and Ligatures

Hindi, like many Indic scripts, includes a variety of ligatures and conjunct characters. To support commonly used consonant conjuncts in Hindi, we’ve assigned त्र् (tr), क्ष् (kss), श्र् (shr), and ज्ञ् (jny) to the Alt + Shift positions of specific keys on desktop keyboards. On mobile keyboards, where the Alt key is not available, these conjuncts can be accessed by long pressing the keys Y, U, I, and O, respectively. This design ensures that these frequently used clusters remain easily accessible across both desktop and mobile platforms.


Keyboard Design Implications

If you're exploring the Hindi script and its usage patterns, understanding the Hindi keyboard layout is essential. Whether you're using a Hindi phonetic keyboard or a traditional Hindi keyboard, character frequency insights can help optimize typing experiences and input methods. This analysis sheds light on how Hindi characters are used in real-world text, informing better design for digital tools and keyboards.


The insights from this frequency analysis directly inform our strategy for designing Varta Hindi phonetic keyboard. Frequently used characters are placed in more accessible positions (home row or index finger positions), while less common ones are assigned to secondary layers (e.g., Shift or long-press positions). This ensures a balance between comprehensive script coverage and ease of use. To simplify the design and reduce typing errors or invalid glyph combinations, we chose not to include individual vowel signs. Instead, the system automatically generates the correct vowel sign based on the consonant and following vowel, streamlining the input process.

Continuing with our initiative to develop optimized and user-friendly keyboard layouts for various Indic languages, we conducted a detailed character frequency analysis for Kannada. Using large-scale monolingual datasets collected from diverse web sources, this study aimed to uncover real-world usage patterns of Kannada characters to inform better design decisions for digital tools. This post lists the outcomes and our findings regarding the detailed character frequency analysis undertaken and how it guided the keyboard layout design for Kannada.


Dataset Overview

To ensure statistical robustness in our analysis, we collected a large Kannada dataset from multiple sources in the web, including from:

  • IndicCorp
  • Leipzig Kannada Corpus
  • Wikipedia articles
  • Samanantar v0.3 (En-Indic; Indic-Indic)
  • Kannada News Dataset

After data pre-processing and cleaning of the dataset, we arrive at following statistic for this:

  • Total tokens: 1.567 billion
  • Unique tokens: 14.825 million

This large and diverse dataset provided a solid foundation for analyzing character usage trends across Kannada as being used in modern daya.


Overall Character Frequency Analysis

The core of our analysis is a character frequency heatmap, where vowels are represented in columns and consonants in rows. Each cell in the matrix reflects the frequency of a specific vowel, consonant or consonant-vowel (CV) combination, with color intensity ranging from light yellow (low frequency) to dark purple (high frequency).

Heatmap showing the frequency distribution of Kannada characters, with vowels arranged in columns and consonants in rows.

High-frequency vowels like ಅ (a), ಇ (i), and ಉ (u) appear prominently across many consonants, indicating their central role in Kannada phonology. At the same time, characters such as ನ (n), ಮ (m), and ರ (r) show consistently high usage across vowel combinations, suggesting their foundational presence in the language.

An interesting pattern observed in the heatmap is that hard consonants (such as ಗ (ga), ಡ (dda), and ದ (da)) generally appear more frequently than their soft counterparts (such as  ಕ (ka), ಟ (tta), and ತ (ta)). This trend suggests a phonetic preference unique to Kannada, differing from other closely related languages like Telugu and Malayalam. These insights are particularly valuable for keyboard layout optimization, as they help prioritize the placement of more frequently used characters for improved typing efficiency.

Vowel Frequency Analysis

To better understand the distribution of vowel usage in Kannada, we analyzed the frequency of individual vowel sounds using a dedicated heatmap by summing the frequencies across the rows from the above heatmap. The results reveal clear patterns in how vowels are used across the language:
Heatmap showing the usage frequency of Kannada vowel sounds. Frequencies range from 0M to 1.5B, with colors from purple to yellow indicating high to low frequencies respectively.As in other Indic languages, the shorter vowels are more frequent than their longer counterparts. The vowels ಅ (a), ಇ (i), and ಆ (aa) are the frequently used either as standalone vowels or as vowel signs in a consonant-vowel (CV). Vowels like ಉ (u) and ಐ (e) also show significant overall usage. The ardhakshara (virama) sign occurs more than in billion instances (last cell in the heatmap) in this dataset, underscoring the frequent use of pure consonants in Kannada. This pattern aligns with other Dravidian languages such as Telugu and Malayalam, where the virama plays a similarly prominent role in forming consonant clusters and suppressing inherent vowels.

However, a notable divergence emerges in Kannada: the akāra CV form (first cell) exhibits a higher frequency than the virama, a trend not observed in other Dravidian languages, where virama usage often surpasses or is comparable to akāra CV combinations. This suggests a greater reliance on vowel-led syllables in Kannada, possibly reflecting phonotactic or orthographic preferences unique to the language.

Consonant Frequency Analysis

We then analyzed the frequency of the consonant by performing a row-wise sum over the frequency matrix. This gives us the frequency of each consonant across all its CV forms as captured in the heatmap below. The first cell captures the frequency of all the vowel forms and can be ignored from this analysis.
Heatmap titled 'Kannada Consonant Sounds Usage Frequency Heatmap' showing the frequency of various Kannada consonants in millions. Darker colors indicate higher usage.
The consonants ರ್ (r), ದ್ (d), and ತ್ (t) are the most frequently used, highlighting their central role in Kannada phonology and word formation. Characters like ಕ್ (k) and ಗ್ (g) also show high usage, each exceeding 360M occurrences, indicating their importance in everyday vocabulary. Aspirated and retroflex consonants such as ಘ್ (gh), ಙ್ (ng), ಝ್ (jh), and ಞ್ (ny) appear very infrequently, with some registering near-zero usage. These are typically found in Sanskrit-derived or less common words.

As noted earlier, the hard consonants are slightly more frequent than their softer equivalents (except for ಕ್ (k) and ಪ್ (p)). However, in keeping with the conventions followed in both the Kannada InScript and Varta keyboard layouts for other Indic languages, we chose to place the soft consonants on the home or bottom row, while assigning the hard consonants to the top row. This arrangement maintains consistency across layouts and supports more intuitive typing patterns.

Special Characters and Ligatures

Kannada, like many Indic scripts, includes a variety of ligatures and conjunct characters. However, to support commonly used consonant conjuncts in Kannada, we’ve assigned ತ್ರ್ (tr), ಕ್ಷ್ (kss),  ಶ್ರ್ (shr), and ಜ್ಞ್ (jny) to the Alt + Shift positions of specific keys on desktop keyboards. On mobile keyboards, where the Alt key is not available, these conjuncts can be accessed by long-pressing the keys Y, U, I, and O, respectively. This design ensures that these frequently used clusters remain easily accessible across both desktop and mobile platforms.


Keyboard Design Implications

Our character frequency analysis for Kannada offers valuable insights for anyone working with the Kannada keyboard layout. From native speakers to developers building Kannada phonetic keyboards, understanding which characters are most frequently used can enhance typing efficiency and user experience. This data-driven look at the Kannada keyboard supports smarter design and localization.


The insights from this frequency analysis plays a key role in designing the Varta Kannada keyboard. Frequently used characters are placed in more accessible positions (home row or index finger positions), while less common ones are assigned to secondary layers (e.g., Shift or long-press positions). This ensures a balance between comprehensive script coverage and ease of use. To improve usability, we opted not to include standalone vowel signs. Instead, vowel signs are generated automatically from consonant-vowel sequences, which simplifies the layout and minimizes input errors.

As part of our ongoing effort to create optimized and accessible keyboard layouts for Indic languages, we carried out an in-depth character frequency analysis for Telugu. Drawing from large-scale monolingual datasets sourced from across the web, this study focused on identifying real-world usage patterns of Telugu characters. This post lists the outcomes and our findings regarding the detailed character frequency analysis undertaken and how it guided the keyboard layout design for the language.


Dataset Summary

Our Telugu analysis is based on a large and diverse dataset compiled from multiple sources in the web including the following key resources.

  • IndicCorp
  • Leipzig Telugu Corpus
  • Samanantar v0.3 (En-Indic; Indic-Indic)
  • Telugu News Articles Dataset
  • Telugu Books Dataset

After pre-processing, this dataset contained over 1.45 billion total words and 12.3 million unique words, providing rich & diverse data for studying character frequency patterns in the language. This extensive dataset provides a strong statistical foundation for understanding character usage patterns in Telugu helping, us design an optimal keyboard layout.


Overall Character Frequency Heatmap

We created a heatmap to visualize the frequency of Telugu characters, where vowels are represented in columns and consonants in the rows. Each cell represents the frequency of a basic vowel, consonant or consonant-vowel (CV) combination, with darker shades indicating higher usage

A heatmap showing the usage frequency of Telugu letters, with vowels as columns and consonants as rows. Darker colors represent higher frequencies, highlighting commonly used characters.

Vowels such as అ (a) dominate the frequency spectrum, similar to how 'e' and 'a' are dominant in English. Consonants like క (ka), న (na), and ల (la) also show high usage, reflecting their foundational role in Telugu script. A number of characters, particularly aspirated or Sanskrit-derived forms, show very low or near-zero usage, indicating their limited role in everyday Telugu. We also note a unique pattern where long vowels like ఓ (oo) are more frequent than their short counterparts, a trend not commonly seen in other Indic scripts.


Vowel Frequency Analysis

By calculating the column-wise sum of the above character frequency matrix, we obtain the frequency heatmap of each vowel, either in its base form or as a vowel sign in a consonant-vowel (CV)/ consonant conjuncts.

Heatmap showing character frequencies of Telugu vowels in their base as well as CV forms. Colors range from purple (high frequency) to yellow (low frequency), highlighting the relative usage of each vowel sound. As in many other languages, the short vowel forms—అ (a), ఇ (i), and ఎ (e)—are generally more frequent than their long counterparts. However, Telugu exhibits a unique pattern with the long vowels ఏ (ee) and ఓ (oo), which occur significantly more often than their corresponding short forms. Notably, ఓ (oo) is used nearly five times more frequently than ఒ (o), highlighting a distinct phonological preference in Telugu. Vowels like ఊ (U) and ఋ (vR) appear far less frequently, indicating limited usage in modern Telugu text. These insights are crucial for prioritizing vowel placement in keyboard layouts.


The final cell in the heatmap represents the frequency of the Telugu pollu sign, which denotes a pure consonant (i.e., without an inherent vowel). Interestingly, its distribution is comparable to that of the CV forms with the vowel అ (a)—found in the first column—indicating a similar usage pattern across consonants.


Consonant Frequency Analysis

We then started analysis of the Telugu consonants. By summing the rows of the character frequency chart, we obtained the frequency of each consonant, across its different vowel combinations. This row-wise analysis reveals the most commonly used consonants in Telugu.

Heatmap titled 'Telugu Consonant Sounds Usage Frequency Heatmap' showing the frequency of various Telugu consonants in millions. Darker colors indicate higher usage.
The consonant forms of ర్ (r), న్ (na), and ಲ್ (la) emerge as the most frequently used in Telugu, underscoring their central role in the phonetic structure of the language. Following closely are క్ (ka), త్ (ta), and ప్ (pa), each with approximately 300 million occurrences. In contrast, aspirated and less commonly used consonants such as ఙ్ (nga), ఝ్ (jha), and ఢ్ (ḍha) appear only rarely, reflecting their limited presence in contemporary Telugu usage.

Special Characters and Ligatures

Telugu, like many Indic scripts, includes a variety of ligatures and conjunct characters. However, to support commonly used consonant conjuncts in Telugu, we’ve assigned త్ర్ (tr), క్ష్ (kss),  శ్ర్ (shr), and జ్ఞ్ (jny) to the Alt + Shift positions of specific keys on desktop keyboards. On mobile keyboards, where the Alt key is not available, these conjuncts can be accessed by long-pressing the keys Y, U, I, and O, respectively. This design ensures that these frequently used clusters remain easily accessible across both desktop and mobile platforms.

Keyboard Design Implications

Our Telugu character frequency analysis is a must-read for those interested in refining the Telugu keyboard layout. With growing demand for intuitive Telugu phonetic keyboards and mobile-friendly Telugu keyboard solutions, this data helps developers to validate and appropriately align their design based on actual language usage patterns.

The insights from this frequency analysis directly inform our design strategy for the Varta Telugu phonetic keyboard. Frequently used characters are placed in more accessible positions (home row or index finger positions), while less common ones are assigned to secondary layers (e.g., Shift or long-press positions). This ensures a balance between comprehensive script coverage and ease of use. To streamline the typing experience, we decided not to include separate vowel signs. Instead, the correct sign is automatically generated from the consonant and vowel input, reducing errors and simplifying the keyboard design.

    ]]>    Fri, 30 May 2025 16:39:42 +0530    <![CDATA[Designing a New Input Method for Tamil]]>https://www.maadhyamik.com/blogs/post/designing-a-new-input-method-for-tamil

    The present input methods for Tamil, while providing reasonable support for using the language in Computers and other devices, they have several shortcomings. We will explore the current input methods and their shortcomings briefly before proposing a new Input Method for Tamil that can be used in both keyboard based and touch devices.

    Current Input Methods:

    Presently there are 3 predominant input methods that are in wider use.

    • Tamil99
    • Murasu Anjal
    • Google Keyboard (GBoard)

    The inadequacy of existing Input methods for Tamil and the idea for a new Input Method for the language has been around for several years [2]. More recently Elango Cheran published a detailed blog post [1] not only explaining the shortcomings of the current Input methods but also expounding his idea of exploiting the phonemic nature of the Tamil alphabets for the new Input method. Here is the brief summary of the key shortcomings of the current Input methods.

    Unnatural Design: In Tamil Consonant Vowels such as  'க' and 'தை' are generated by the combination of pure consonants 'க்' and 'த்' with the vowels 'அ' and 'ஐ' respectively. Thus the Vowels and the Consonants, which form the basic units of the sounds (phonemes) in Tamil, should be the basis of designing a good Input method. Several Input methods including the Tamil99 follow the unnatural design of Vowels and Consonant vowels (CV) such as 'க', 'ங' and 'ச', as the basic units in the Keyboard. To be fair, this design came to be used, because these CV characters

    Coming back to the Input methods, one of the unintended consequence of this design approach is that, this can produce illegal character sequences in Tamil such as with dangling consonant vowel modifiers such as '்', '

    Transliteration Dependency: Murasu Anjal and other transliteration keyboards, rely on users being familiar with the English alphabet and actually inputting the Tamil words in transliterated English letters, which are then transliterated back to Tamil. This method is hugely popular due to the high English literacy among the Tamil speakers the population around the world. However, we believe this is doing more harm because the speakers no longer have to learn the script but only the sounds in the language. Secondly, there are multiple ways to represent a Tamil character in English, because the variations in the sounds in the two languages.

    Non-adherence to QWERTY layout: Most of the Tamil keyboards do not adhere to the widely-used QWERTY layout in terms of the key positions reserved for punctuations and other symbols in the keyboard. These Input methods assign Tamil characters in these positions. Consequently, the bilingual users using QWERTY will find it difficult to switch back and forth between English and Tamil typing and they will be forced to learn and follow the different key positions for typing punctuations and symbols while using Tamil.

    GBoard Design Incongruity: The Google Keyboard or GBoard for Tamil is the soft key layout launched for touch devices. It lays out the Vowels and Consonant Vowels ('அ' வரிசை such as 'க', 'ங', 'ச', ...) in a 9x4 matrix. The vowel character panel on the left changes every time a consonant vowel is pressed to show its other CV variations. The layout uses a simplistic sequential positional of characters in the alphabet, without any concern for either optimizing finger movements or the character frequency based layout design. Combined with the incongruity of ever changing vowel panel, GBoard's design choice is probably the least efficient Tamil key layout in use.


    A New Input Method - Design Principles:

    We want to design a new Input Method for Tamil that address the shortcomings in the existing one and also makes it easier to learn the new method with a short learning curve. Based on our research, we decided on the following design goals for the new Input method.

    1. A design that adheres to and exploits the Phonemic nature of Tamil, taking the phonemes as the basic unit
    2. Frequency analysis of base phonemes and consonant vowel combination in order to achieve an optimal design that speeds up touch typing in computers and equivalently reduces finger movement in touch devices
    3. Intuitive arrangement of keys to make the learning easier that is consistent across different platforms and devices
    4. Prevent any illegal character sequences in the output text
    5. Maximize compatibility with the QWERTY keyboard to make the transition between English and Tamil typing seamless and easier.
    6. Eliminate the forced requirement for the user to know other script/ language and instead facilitate typing in the Tamil script

    It should be noted that, the same design principles could be used for designing better Input methods for other Abugida languages as well.


    Designing the Input Method:

    We started the design by identifying Tamil corpus data for doing usage frequency analysis of the characters in the language. We identified large enough corpora (approx. 537M words) from two different sources as below:


    Frequency Analysis:

    Our goal is to understand the usage frequency of basic phonemes as well as for the full set of Tamil alphabets including the consonant vowel characters. Once we understand the usage frequency of the phonemes and the full set of alphabets, we can exploit this information to design the keyboard layout. It should be noted that we have omitted the Sanskritized characters (வடமொழி எழுத்துக்கள்) 'ஜ்', 'ஶ்', 'ஷ்', 


    Among the top-10 most frequent characters are, we have 5 consonant vowels and 4 'அ' ending CVs and 

    1. Consonants: ம், ர், ல், க் and ன் - 349.13M
    2. 'அ' ending CVs: க, த, ப and வ - 306.19M
    3. 'உ' ending CV: து - 64.63M

    Thus by using the base phonemes (vowels and pure consonants) for out keyboard layout, would result in a saving of nearly 43M keystrokes for this dataset. Now consider two more heatmaps i) by characters ending with vowel sounds (column-wise sum of the above heatmap) and ii) by the characters for each consonant-vowel series (row-wise sum).

    Freq analaysis of characters ending with Vowel sound

    Notice that the pure consonants (right-most cell) tend to be more frequent than any consonant vowel series. Here again by using the basic phonemes as the keys instead of the 'அ' ending consonant vowels, these pure consonants can be typed with a single key press as opposed to two presses, saving about 37M keystrokes on this dataset. Also notice that the vowels and CVs ending in short form vowel sound are much more frequent than their long form counterparts.


    Using the frequency statistics of the Vowels (first two in the first heatmap) and the Consonant vowels above, we can design optimal keyboard layout to minimize the movement of fingers and to use the dominant fingers for the high frequency phonemes. The next section discusses the design decisions and explains our Tamil Phonemic keyboard layout.


    Phonemic Keyboard Layout Design for Tamil:

    As we mentioned earlier in our design goals, we want the new keyboard layout to be easier for the users to learn and use across different devices. We want to minimize  Given the constraints of available keys and total required keys, we had to make certain design decisions in the character assignment to the key positions.

      1. We want to use Home row of the keyboard for the Vowels and some high-frequency Consonants in the language
      2. We also believe that the dominant index and middle finger keys in two non-Home rows should take precedence over the Home row keys with weaker fingers. We'll be using this later in optimizing the character assignment to the keys.
      3. Given the high frequency of short form vowel ending characters, we have retained the short vowels in the Home row and assign the corresponding long form vowels to the same key in the Shift row. Following the wider convention, we've assigned the vowels on the left side of the keyboard.
      4. Most of the Consonants are going to be assigned in the right hand side of the keyboard to exploit the dominant hand for the majority of the population. Note that this arrangement allows the CVs to be typed efficiently by a mix of both hands, without making the same hand/ finger to move to a different position for typing a single character.
      5. Based on our observation #2 above, the frequent Consonants starting with 'க்' and 'த்' are assigned in the dominant finger positions in the Home row and the rows above and below. We assign the rest of the consonants to the weaker key positions in the decreasing frequency order.
      6. We now specifically consider the case of மெல்லினம் (nasalized consonants), which are typically be followed by the corresponding வல்லினம் (plosive/ stop consonant) in the Tamil text. Thus, it made sense for us to place these nasalized consonants on the left side of the keyboard (above and below the home row) so that the following வல்லினம் can be typed with the right hand. We made an exception for 'ம்' and assign it to the dominant key position on the right side, due to its high frequency in both Consonant and CV forms.
      7. On the Shift key layout, we assigned the Tamil numerals right below the roman numerals to make the typing intuitive and easier. Additionally, the Sanskritized consonants and other Tamil symbols are assigned on this Shift layout.

    The screenshots of the new keyboard layout for the regular and Shift keys are below.





    Input Method Analysis:

    Based on the keyboard layouts for the three input methods, viz Anjal, Phonemic and Tamil99, we analyzed their efficiency and ease of typing in two ways. We first calculated the number of absolute keystrokes required to type the Tamil words in the above corpora of 537M words. To keep the analysis simple, we ignored the punctuations and any non-Tamil words/ characters for this. We also ignored the shift key here because the shift key is pressed simultaneously with the key following it. Here are the absolute number of keystrokes required for typing the above Tamil corpora by the 3 input methods.

      • Anjal : 4,470,795,879
      • Phonemic : 4,045,040,635
      • Tamil99 : 4,124,838,873

    The Phonemic method requires the least number of keystrokes among the 3 methods; specifically it requires 80M fewer keystrokes than Tamil99. This is because, the pure consonants are usually frequent than their CV combination. Tami99 requires an additional keystroke '்' for typing the pure consonants. For Anjal, we used the standard transliteration mapping as suggested in the Sellinam app, thus requiring two keystrokes for each long vowel as well as for long CV combinations.

    We then analysed the heatmap on the keyboard layouts of the three input methods to see which keys are typed in more frequently and their relative position in the keyboard. We plotted the heatmap on the 3 keyboard layouts separately for this analysis. As above, we ignored the punctuation marks and non-Tamiil words to keep this analysis simple. However, we considered the shift key in this analysis.


    The layout will be easier for typing if the frequently typed keys are in the position of dominant fingers of both hands or in the Home row of the keyboard. The Anjal keyboard is clearly the least efficient option as the most of the frequently used keys are outside of the dominant finger positions of the keyboard.


    Between the Phonemic and Tamil99 keyboards, the frequent keys are mostly located in the dominant finger position, which makes the typing easier. The dominant left and right index fingers positions (in all 3 rows) alone account for 61.22% and 46.32% of the overall typing in Phonemic and Tamil99 keyboards respectively. This difference of 15% is significant and makes the Phonemic layout a better (in terms of ease of use) option than the Tamil99 keyboard.


    We then look at the percentage of typing for the keys in the Home row, which is the usual resting position for the hands when not typing. It thus has the advantage that the user will not have to move their hands from its resting position. The Phonemic layout accounts for 58.33% of the Home row typing, while the Tamil99 is slightly better with 61.83% of overall typing. We believe this small difference of Home row typing is far outweighed by the advantage gained in the Phonemic keyboard layout by the dominant index fingers across all the rows. In addition to the efficiency in typing, the new Phonemic keyboard layout offers other advantages over the Tamil99 keyboard as discussed earlier in this post.
