The Zarma alphabet uses the following letters: a, b, c, d, e, f, g, h, i, j, k, l, m, n, ɲ, ŋ, o, p, r, s, t, u, w, y, z. Nasal vowels are written with a tilde or a following or . Officially, the tilde should go under the vowel ("so̰ho̰"), but many current works write the tilde over the vowel ("sõhõ"). Also, v may be used in a few words of foreign origin, but many Zarma cannot pronounce it.
