What ஓ means
On Tamil99, x types the standalone letter ஓ.
The x key sits beside c, which produces the short-o letter ஒ. For a syllable with a consonant, type the consonant first and then the vowel; Tamil99 places the long-o sign around the consonant when needed.
What sound does ஓ make?
It marks Tamil’s long “o” vowel.
Tamil-Brahmi, an adaptation of the Brahmi script for Tamil, is the earliest attested script tradition used to write Tamil. By the middle of the third century BCE, it appeared in Tamil inscriptions on sheltered rock overhangs and pottery. Later Tamil writing also used the Vatteluttu and Grantha script traditions.
Where a Tamil syllable begins with a vowel, the independent letter ஓ is used. When the same vowel follows a consonant, Tamil uses the dependent vowel sign ோ, as in கோ.
Inside a word, ஓ spells a vowel; alone, it can be a reaction.
Keep long-o ஓ distinct from short-o ஒ.

Questions people ask
1Why does ஓ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
