Mutsun language From Wikipedia
- Mutsun is both: a name of one sub-group of the Ohlone indigenous people of Alta California; and the name of the native language the Mutsun tribes spoke.
Mutsun (also known as San Juan Bautista Costanoan) is an Utian language in the Ohlone/Costanoan language family that was spoken in Northern California by the division of the Ohlone who lived in the Mission San Juan Bautista area.
Ascencion Solorsano, who died in 1930, left mass amounts of language and cultural data of the Mutusn. The Spaniard wrote a grammar of the language, and linguist John Peabody Harrington collected very extensive notes on the language from Solorsano. Harrington's field notes formed the basis of the grammar of Mutsun written by Marc Okrand as a University of California dissertation in 1977,  which to this day remains the only grammar ever written of any Costanoan language.
