Mutsun (also known as San Juan Bautista Costanoan) is an Utian language that was spoken in Northern California. It was the primary language of a division of the Ohlone people living in the Mission San Juan Bautista area.
Ascencion Solorsano amassed large amounts of language and cultural data specific to the Mutsun. The Spanish Franciscan missionary and linguist Felipe Arroyo de la Cuesta wrote extensively about the language's grammar, and linguist John Peabody Harrington made 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. Scholars from the U.S., Germany and the Netherlands have discussed methods that could facilitate the revitalization of Mutsun.
The Amah Mutsun band is currently working to restore use of the language, using a modern alphabet.
