About Toda

Toda is a indigenous Dravidian language, spoken by the Toda people, who live in the Nilgiri Hills of South India. It is noted for its fricatives and trills. The language is considered to have originated from the Toda-Kota subgroup of South Dravidian. Linguist Bhadriraju Krishnamurti does not consider the existence of a single Toda-Kota branch and says Kota split first and Toda later as Kota doesn't have the centralized vowels of other Tamil-Toda languages.
