abstract:Paleosiberian (Palaeosiberian, Paleo-Siberian) languages or Paleoasian languages (Palaeo-Asiatic) (from Greek palaios, "ancient") is a term of convenience used in linguistics to classify a disparate group of linguistic isolates as well as a few small families of languages spoken in parts both of northeastern Siberia and of the Russian Far East. They are not known to have any linguistic relationship to each other; their only common link is that they are held to have antedated the more dominant languages, particularly Tungusic and latterly Turkic languages, that have largely displaced them.
