Tone-accent and prosodic domains in Wolaitta

In Wolaitta, an Omotic language spoken in the south-central pan of Ethiopia. simple phonological words are usually restricted to one high tone-accent per word. Nouns and adjectives have a similar tone-accent pattern, while verb roots differ from these in many respects.

In nouns this depends on definiteness and the location of tone-accent in the citation form, while in verbs it is determined by the presence or absence of high tone-accent on the verb root and the type of suffix attached to it.
