Zande and Chamba-Daka are Adamawa-Ubangi (Niger-Congo) languages. The Zande agent noun is identical with the completive verb. Some agent nouns are instrumental or designate the process itself. The Chamba-Daka agent noun is a compound postposing the “infinitive” to the noun meaning ‘person’. It refers only to the subject argument of the source verb. Both languages have a semantically related compound: the “artist” noun meaning ‘owner, skillful user of (a material object)’ or ‘individual (with intrinsic attribute)’. The semantic range of the artist noun in both languages is similar. The artist noun may be formed with the “infinitive”; it then contrasts modally with the agent noun.
