Millcayac
Millcayac language
Extinct Warpean language of Argentina
Millcayac (Milykayak) was one of two known Warpean languages.[1] It was native to Cuyo in Argentina, but was displaced to Chile in the late 16th century. Luis de Valdivia wrote a grammar, vocabulary and religious texts.[2] The people became Mestizo and lost their language soon after. [citation needed]
