Avagraha symbol used to indicate prodelision of an अa in many Indian languages as shown below. It is usually transliterated with an apostrophe, as in the Sanskrit philosophical expression शिवो ऽहम्Śivo ’ham (Śivaḥ aham without sandhi) ‘I am Shiva’. The avagraha is also used for prolonging vowel sounds in modern languages, for example Hindiमाँऽऽऽ! for ‘Mãããã!’ when calling to one’s mother, or when transliterating foreign words in instant messaging, for example, coOol can be transliterated as कूऽल .
The character is also sometimes used as a symbol to denote long or heavy syllables, in metrical poetry. For example, the syllables in the word छंदःchandaḥ ‘metre’ (in nominative) can be denoted as "ऽ ऽ", meaning two long syllables. (Cf. other notations in entry "Systems of scansion".)
