Ramarama, also known as Karo, is a Tupian language of Brazil. Unusually for the indigenous languages of South America in general and Tupian in particular, Ramarama is a fairly analytic language, with limited affixation and a strict SOV word order. However, the language also displays complex processes of morphophonological alternation, segmental allophony, and interaction between segmental and suprasegmental phonology.
