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 about 20 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.
