Gǀwi has both velar and uvular clicks. (However, see Nǀu language for an alternative analysis of this distinction.) Altogether there are thirteen such accompaniments, or effluxes; all 52 possible clicks are found. Except for the lack of a bilabial click release, this inventory is nearly identical to that of ǂHõã.

Most words are of the form CV, CVV, CVCV, CVN, where C stands for a consonant, V for a vowel, and N for a nasal consonant (m, n). In CVCV words, only a limited set of consonants (b m ɾ n j w) may occur in medial position (the second syllable). Of these, two (n, ɾ) may not occur at the beginning of a word. /ŋ/ only occurs in mimesis.
The modal vowels and the pharyngeal vowels aˤ oˤ oaˤ occur as the first vowel of disyllabic roots, CVCV (CVV), whereas o u do not occur with a nasal coda, CVN, although a diphthong not found elsewhere, oa, does. There are restrictions on which vowels may follow which consonants.
The modal vowels and the nasal vowels ã ẽ õ occur as the second vowel of disyllabic roots, CVCV or CVV, though only modal vowels may follow the medial consonants b r, and only nasal vowels follow the medial consonants m n.
