Millcayac
Millcayac是Huarpean 语系的一种语言，过去分布在阿根廷，现已消亡。
Millcayac (Milykayak) was one of the Huarpean languages. 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. The people became Mestizo and lost their language soon after.
