the het population was decimated by the end of the eighteenth century by epidemics, which facilitated the mapuche absorption of its territory and its survivors rapid araucanization at the cultural level that consolidated them into the puelche. for this reason it is today difficult to find evidence of the het languages. of querandí (diuihet) we only have two sentences and a few words, recorded by french sailors around 1555. based on this admittedly inadequate data, viegas barros showed that querandí may have been closely related to puelche. viegas barros (2005) further attempted to demonstrate that puelche is more distantly related to the chon languages to its south.
