A simplified orthography is a variant of the old Bridges system, created for online use on the Waata Chis discussion list on Yahoo Groups and elsewhere. It has tense and lax vowels as well as voiced and voiceless consonants. In the system, tenseness is marked by colon (:) following the vowel sign: a, a:, ai, au, e, e:, i, i:, iu:, o, o:, oi, u, u:, v (pronounced as a schwa, not ), all corresponding to unique graphemes in the Bridges orthography. The consonants are b, d, ch, f, g, h, j, k, l, m, n, ng, p, r, s, sh, t, w, x, y, z, all corresponding to unique Bridges graphemes. Some are found only in restricted environments. The phonemes hm, hn, hl, hr, hw, and hy are used as well, and are digraphs in the earlier Bridges writings, but single graphemes in later ones.
