The Asa (Aasá) language, commonly rendered Aasax (also rendered as Aasá, Aasáx, Aramanik, Asak, Asax, Assa, Asá^[2]), is an extinct Afroasiatic language formerly spoken by the Asa people of Tanzania. The language is extinct; ethnic Assa in northern Tanzania remember only a few words they overheard their elders use, and none ever used it themselves. Little is known of the language; what is recorded was probably Aasa lexical words used in a register of Maasai, similar to the mixed language Mbugu.^[3]

Asa is usually classified as Cushitic, most closely related to Kw'adza. However, it might have retained a non-Cushitic layer from an earlier language shift.

The Aramanik (Laramanik) people once spoke Asa, but shifted to Nandi (as opposed to Maasai).

Asa is known from three primary sources: two vocabulary lists from 1904 and 1928, and a collection by W. C. Winter from 1974.^[4]
