Kawésqar (Qawasqar), also known as Alacaluf, is an language isolate spoken in southern Chile by the Kawésqar people. Originally there were three regional dialects: northern, central, and southern. (Kakauhua, a.k.a. Chono, is sometimes listed as a related language, but it is completely unattested.) Only a dozen speakers of Kawesqar remain, half of them on Wellington Island, off the southwestern coast of Chile.
The alphabet in use is as follows : a, æ, c, c', e, f, h, i, j, k, k', l, m, n, o, p, p', q, r, rr, s, t, t', u, w, x. However, there are reported to be differences between dialects, and some sounds that are not represented here.
