Why are there 247 Tamil letters?

The Tamil set has 12 uyir vowels, 18 mei consonants, 216 uyirmei formed by combining each of the 18 consonants with each of the 12 vowels, and 1 aytam. That totals 247: 12 plus 18 plus 216 plus 1.

The Tamil script is an abugida with a famously regular structure: a small set of vowels and consonants combine to produce the full character inventory. This free reference lays out all 247 letters — the 12 uyir vowels, the 18 mei consonants, the 216 uyirmei combinations, and the aytam — with romanization, search, and click-to-copy.

How it works

The grid is built programmatically. Each of the 18 consonant rows is paired with each of the 12 vowel columns:

  • The first column is the inherent-vowel form, the bare consonant (read ka), because the inherent vowel needs no sign.
  • The remaining eleven columns attach a dependent vowel sign, producing கா, கி, கீ, and so on.
  • A separate first cell on each row shows the pure consonant, or mei, written with the pulli , such as க்.

Adding it up: 12 standalone vowels, plus 18 pure consonants, plus the 18 × 12 = 216 uyirmei, plus the single aytam , gives the classic total of 247.

Tips and notes

Use the filter box to jump to a syllable by its romanized form; typing or t narrows the grid to the relevant rows and highlights matches, which is useful for learners practising a particular consonant series. Click any glyph to copy it, so you can paste characters into documents even without a Tamil keyboard.

The regularity of the grid is what makes Tamil literacy fast to bootstrap: once you know the 18 consonants and 12 vowels and how the vowel signs attach, you can read and write any of the 216 uyirmei without memorising each as a separate symbol.
