How it works
A Tamil letters chart to copy from: the 12 vowels and the aytham, the 18 consonants, then all 216 letters that a consonant and a vowel make together. The Latin spellings under the letters follow ISO 15919.

How a consonant and a vowel join
A consonant written alone already carries the vowel a: க is ka. A dot on top, the pulli, takes the vowel away and leaves க், k. Any other vowel is added as a sign: கா is kā, கி is ki, கை is kai. A sign can stand right of its consonant, left of it or on both sides; the copied letter always holds the consonant first.
Three kinds of consonant
Tamil sorts its 18 consonants into three groups of six: hard, soft, which holds the nasals, and medium. The Grantha letters, such as ஜ ja and ஹ ha, stand outside that count: they are supplementary letters for sounds Tamil took in later.
- ஃ, the aytham, written before ப gives the f of English words: ஃப.
- Tamil has one sign each for 10, 100 and 1000: ௰, ௱ and ௲.
