Wiktionary:About Proto-Algic

Proto-Algic is the ancestor of the Algic languages: Wiyot, Yurok, and Proto-Algonquian (whence the Algonquian languages). It is a second-level proto-language, a proto-language whose reconstruction depends upon data from another proto-language.

Proto-Algic was spoken about 7 000 years ago in the American Northwest, somewhere around the Columbia Plateau.

Vowels
Proto-Algic had four basic vowels, which could be either long or short:
 * long: *i·, *e·, *a·, *o·
 * short: *i, *e, *a, *o

Consonants
Proto-Algic had a large inventory of consonants (see ). The identity of the phoneme which is customarily reconstructed as ɬ /ɬ/ is uncertain; in Proto-Algonquian, which has the same phoneme, it is sometimes alternatively reconstructed as θ /θ/ (see WT:AALG#Consonants). As in Proto-Algonquian, it is unclear if č /tʃ/ was an independent phoneme or only an allophone of c and/or t.
