The Shasta language is an extinct Shastan language formerly spoken from northern California into southwestern Oregon. It was spoken in a number of dialects, possibly including Okwanuchu. By 1980, only two fluent speakers, both elderly, were alive. Today, all surviving Shasta people speak English.
Length is distinctive for consonants in Shasta. The affricates are generally written ⟨c⟩ and ⟨č⟩, and the ejectives indicated by an apostrophe written over the character. The phoneme /j/ is represented by ⟨y⟩.
