These languages shared many similarities in grammar, vocabulary, and pronunciation, but there were also distinctions among them. Unfortunately, due to the devastating impact of colonization and diseases brought by the Spanish colonizers, most of these languages are no longer spoken today. Some efforts are being made to revitalize and preserve the Ohlone languages and cultural heritage.
