Car (Pū) is the most widely spoken Nicobarese language of the Nicobar Islands in the Bay of Bengal.

Although a member of the Austroasiatic language family, it is typologically much more akin to nearby Austronesian languages such as Nias and Acehnese, with which it forms a linguistic area.

[4] There is a quite complicated verbal suffix system with some infixes, as well as distinct genitive and "interrogative" cases for nouns and pronouns.

[5] Shared morphological alternations: the old AA causative has two allomorphs, prefix ha- with monosyllabic stems, infix -um- in disyllabic stems (note: *p > h onset in unstressed σ).
