Tamil Braille is the smallest of the Bharati braille alphabets.

[1] (For the general system and for punctuation, see that article.)

Vowel letters are used rather than diacritics, and they occur after consonants in their spoken order.

The last two letters, ⠰ ṉ and ⠷ ḻ, are shared with Malayalam, but otherwise ⠰ ṉ is used for the anusvara (nasalization) in other Bharati alphabets, while ⠷ ḻ is also used in Urdu Braille but for the unrelated letter ʻayn.
