Arapaho Language - Phonology

Phonology

Among the sound changes in the evolution from Proto-Algonquian to Arapaho are the loss of Proto-Algonquian *k, followed by *p becoming either /k/ or /tʃ/; the two Proto-Algonquian semivowels merging to either /n/ or /j/; and *m often becoming /b/. Arapaho is unusual among Algonquian languages in retaining the contrast between the reconstructed phonemes *r and (generally as /n/ and /θ/, respectively). These and other changes serve to give Arapaho a phonological system very divergent from that of Proto-Algonquian and other Algonquian languages, and even from languages spoken in the adjacent Great Basin. Some examples comparing Arapaho words with their cognates in Proto-Algonquian can illustrate this:
