чу́ваш • (čúvaš)
Attested early 16th century in the obsolete form чюваши m pl (čjuvaši). Borrowed from Turkic whence modern Chuvash чӑваш (čăvaš, “Chuvash”), Tatar чуаш (çuaş, “Chuvash”), and Eastern Mari суас (suas, “Tatar”). In the 16th and 17th century the Russian term may have referred to a social estate rather than a particular ethnicity. Further etymology uncertain; there are a number of hypotheses.
