Abstract
Nuer (ISO 6393: nus/Glottocode: nuer1246) is a Nilo-Saharan language (Nilo-Saharan, Eastern Sudanic, Nilotic, Western, Dinka-Nuer). The sound system of Nuer is of particular interest because the language has a rich inventory of vocalic and suprasegmental distinctions, including a large number of vowel phonemes, a voice quality contrast (modal versus breathy), three levels of vowel length, and a tonal inventory that interacts with the voice quality contrast.
