Atallan
Atallan is the name given to the presumed language of the Manteño-Huancavilca peoples, the coastal traders of Ecuador's Guayas, Manabí and Santa Elena region whose culture flourished from about 850 to 1600.
Scholars have grouped the poorly recorded speech of the Manta and Huancavilca, together with that of Puná and Tumbes, into a hypothetical Atalán family, but only a handful of words were ever collected, so its relationship to other languages cannot be established. The Inca never conquered this coast, and after the Spanish takeover the language died out unrecorded, leaving its classification unsettled.
