Auvanna (ஔவன்னா) or auharam (ஔகாரம்) - the twelfth letter of the Tamil alphabet , means the diphthong “АУ”, used at the beginning of a word, transmitted inside the word by means of two diacritical signs surrounding the consonant, corresponding in the Sinhala writing to the signs of kombuv and gayanukitt : க் + ஔ = கௌ.
