Proto-Algic (sometimes abbreviated PAc) is the proto-language from which the Algic languages (Wiyot language, Yurok language, and Proto-Algonquian) are descended. It is estimated to have been spoken about 7,000 years ago somewhere in the American Northwest, possibly around the Columbia Plateau. It is an example of a second-level proto-language (a proto-language whose reconstruction depends on data from another proto-language, namely its daughter language Proto-Algonquian) which is widely agreed to have existed. Its chief researcher was Paul Proulx.

Vowels
Proto-Algic had four basic vowels, which could be either long or short:
long: *i·, *e·, *a·, *o·short: *i, *e, *a, *oConsonants
Proto-Algic had the following consonants:
1 The identity of this consonant is not entirely certain; in Proto-Algonquian, is sometimes alternatively reconstructed as θ /θ/.It is unclear if č /tʃ/ was an independent phoneme or only an allophone of c and/or t in Proto-Algic (as in Proto-Algonquian). In 1992, Paul Proulx theorized that Proto-Algic also possessed a phoneme gʷ, which became *w in Proto-Algonquian and g in Wiyot and Yurok.
All stops and affricates in the above chart have aspirated counterparts, and all consonants, except fricatives, have glottalized ones. Proto-Algonquian significantly reduced this system by eliminating all glottalized and aspirated phonemes.
