Allentiac (Alyentiyak), also known as Huarpe (Warpe), was one of two known Warpean languages. It was native to Cuyo in Argentina, but was displaced to Chile in the late 16th century. Luis de Valdivia, a Jesuit missionary, wrote a grammar, vocabulary and religious texts.Márquez Miranda, Fernando. 1943. Los textos Millcayac del P.

The people became mestizo and lost their language soon after.
