Spencer (2008) is a short grammar of Kwomtari. The language has an SOV[clarification needed] constituent order and nominative–accusative alignment. Both subjects and objects are marked suffixally on the verb. Verbs are inflected for status (mood) rather than for tense or aspect.[2]
The phoneme /ɸ/ is realized as a voiced bilabial fricative [β] intervocalically and voiceless bilabial fricative [ɸ] elsewhere. The realization of the phoneme /ɭ/ is in free variation between a voiced retroflex lateral [ɭ] and a voiced retroflex stop [ɖ].
The unusual vowel phonemes /i̞/ and /u̞/ are of intermediate height between cardinal [i]/[u] and [e]/[o] respectively but without the centralization present in [ɪ] and [ʊ]. They have also been attested in Weri, a Goilalan language of south-east Papua, and certain Dani dialects.[9]
