Tamil Alphabet Explained: Vowels, Consonants, 247 Letters

The Tamil alphabet has 247 letters, but you only need to learn about 30 shapes and 12 vowel signs to read most of it. The 247 break down like this:

The names are a nice way to remember the system. A vowel is the "life" (உயிர் (uyir) ‘life’) of a syllable, a consonant is its "body" (மெய் (mei) ‘body’), and a combined letter is a body with life in it (உயிர்மெய் (uyirmei) ‘life-body’). That is the whole logic of the script: Tamil is an abugida, where each consonant carries a vowel, and you change the vowel by adding a small sign.

If you want to tap through every letter and hear it, the interactive Tamil alphabet chart has all 247 with audio. This post explains how the system works so the chart makes sense.

The 12 vowels (uyir ezhuththu)

Tamil vowels come in pairs: a short one (குறில் (kuril) ‘short’) and a long one (நெடில் (nedil) ‘long’). Length changes meaning, so it matters. கல் (kal) ‘stone’ and கால் (kaal) ‘leg’ differ only in the length of the a.

A note on romanization: on this site we double long vowels (aa, ee, oo). For the long e and long o we write ae and oa in this table so you can tell the pairs apart. In everyday romanization, including the rest of this site, people usually write both as plain e and o (வேணாம் (venaam) ‘don't want’, போறோம் (porom) ‘we're going’), because the word makes the length obvious.

ஔ is rare. You will see it in a few names and old words, and that's about it.

The 18 consonants (mei ezhuththu)

On their own, consonants are written with a dot on top called the புள்ளி (pulli) ‘dot’. The dot means "no vowel": க் is just k. Without the dot, every consonant carries a built-in a: க is ka.

Tamil grammar sorts the 18 into three families of six. This grouping is genuinely useful, because it predicts how letters behave when they sit next to each other.

Hard consonants (வல்லினம் (vallinam) ‘the hard group’)

Soft (nasal) consonants (மெல்லினம் (mellinam) ‘the soft group’)

Medium consonants (இடையினம் (idaiyinam) ‘the medium group’)

Two things trip up almost every beginner here:

1. Tamil has fewer letters than sounds. There is one letter for k/g/h (க), one for s/ch/j (ச), one for t/d (ட and த), and one for p/b (ப). The rule of thumb: at the start of a word or when doubled, the sound is hard (k, t, p); after a nasal it goes voiced (g, d, b); between vowels it softens. So the same க is a k in கடை (kadai) ‘shop’, a g in சிங்கம் (singam) ‘lion’ and an h-like sound in மகன் (magan) ‘son’ for many speakers.
2. Some letters look like twins but aren't. ண/ந/ன are three different n sounds, ல/ள/ழ are three l-type sounds, and ர/ற are two r sounds. They change meaning, and romanization hides the difference, which is why the pronunciation guide spends most of its time on them.

The 216 combined letters (uyirmei ezhuththu)

Here is the good news. You don't memorise 216 letters. You learn 12 vowel signs and apply them to each consonant. This is the full row for க:

Look at where the signs sit:

• After the consonant: ா (aa), and the i/ee hooks on top: ி, ீ.
• Before the consonant: ெ (e), ே (ae), ை (ai). You write and read the sign first, but you say the consonant first: கை is kai, not aik.
• On both sides: ொ (o) and ோ (oa) wrap the consonant, and ௌ (au) puts ெ before and ள after.

The one place you do need to memorise shapes is the u and oo row. Those signs fuse into the consonant differently for each letter: கு, டு, மு, ரு and ழு don't follow one pattern. Spend your extra practice there.

A few more rows to test yourself, then check with the chart:

The aaytham (ஃ)

The 247th letter is the ஆய்தம் (aaytham) ‘the three-dot letter’, written as three dots: ஃ. In classical Tamil it marks a breathy sound, as in எஃகு (ehku) ‘steel’. Today its main job is borrowed sounds: ஃப is used for f, as in ஃபோன் (fon) ‘phone’. You'll meet it rarely.

Grantha letters: the extras you'll still see

Tamil also uses a small set of letters from the Grantha script for sounds that came in with Sanskrit and other languages: ஜ (ja), ஷ (sha), ஸ (sa), ஹ (ha), க்ஷ (ksha) and ஸ்ரீ (sri). They aren't part of the 247, and purists sometimes avoid them, but you'll see them constantly in names, film titles and everyday words like ஜூஸ் (joos) ‘juice’ and the honorific ஸ்ரீ (sri) ‘Sri, a title before names’.

How to actually learn the alphabet

Based on how the system is built, this order works well for adult learners:

1. The 12 vowels first, in their pairs. Say each pair out loud: அ/ஆ, இ/ஈ, உ/ஊ.
2. The 18 consonants with their built-in a, family by family (hard, soft, medium). The three families are small enough to learn one per day.
3. The vowel signs on one consonant (the க row above), then the same signs on two or three more. You'll notice you can already read most of the grid.
4. The u/oo row as its own drill, because those shapes are irregular.
5. Real words as soon as possible. Your own name, family words like அம்மா (amma) ‘mother’ and அப்பா (appa) ‘father’, shop signs, film titles. Recognition speed comes from reading words, not from the chart.

If you want to read Tamil but don't want to start with script, that's a legitimate choice, and we weigh it up in Do you need to learn Tamil script?. And if you have some Tamil text you want to sound out right now, paste it into the transliterator to see it in English letters.

One last thing worth knowing before you start: the letters tell you how written Tamil sounds, and everyday speech often shortens it. The written வேண்டாம் (vendaam) ‘don't want’ is usually spoken வேணாம் (venaam) ‘don't want’. That gap is normal, and spoken vs written Tamil explains it.
