(or anusvaaram) appears in the alphabet of Indian
languages like Sanskrit
and Dravidian languages
and in Devanagari
nasalizes pronunciation of the vowel sound to which it is attached (namely, the
one just preceding it). The exact nature of nasalization depends on the consonant
sound which follows it (or if it is at the end of a word, by the "m" sound). In Sanskrit often the anusvaara is replaced by the corresponding nasal consonant.
