Between stress and tone in Nubi word prosody

Nubi is a language with culminative word prominence, spoken in Uganda and Kenya. The prominence, or accent, falls within a right-edge three-syllable window, and at the phrasal level deaccenting and rhythm-related accent shift occur in specific phonological and morphological contexts. Since accent is used to express morphological categories, and deaccenting and accent shift are morphologically conditioned, the functional load of accent is comparable to that of morphologically conditioned stress in other languages. Accented syllables are associated with H tones, with default L tones appearing between them. Typologically, Nubi is not a stress-accent language, because unlike for example English, it has no stress distinctions independently of the distinction between accented and unaccented syllables. It is also non-tonal, because accent marking is not lexically idiosyncratic, and because it has no option other than to supply a H tone is accented syllables, it is unlike a prototypical intonation language that has pitch accents with discoursal meanings.
