Utian (also
Miwok–Costanoan, previously
Mutsun) is a
family of indigenous languages spoken in the central and north portion of
California,
United States. The
Miwok and
Ohlone peoples both spoke languages of the Utian language family. It has recently been argued that the Utian languages and
Yokuts languages are sub-families of the
Yok-Utian language family (Callaghan 1997, 2001; Golla 2007:76-77). Utian and Yokutsan have traditionally been considered part of the
Penutian language phylum (Goddard 1996:313-319; Mithun 1999; Shipley 1978:82-85).
