This paper argues that Nubi, an Arabic creole spoken in Bombo, Uganda (among other places) escapes a categorization as either a tone language or a stress-accent languages. It could be classified as a pitch accent language in the sense of Beckman (1986), but unlike languages like Tokyo Japanese lacks a class of unaccented words.
