Datapoint Mixed Ma’a/Mbugu/Occurrence of nominal plural markers
Mbugu has a Niger-Congo noun class system in which certain noun classes (marked on the noun as a noun prefix) are semantically plural while others are semantically singular; for some noun classes there is no clear number interpretation. All nouns fall into one of the noun classes, and in that sense all nouns are marked for number. One could argue, however, that number as such is not a category that is grammatically relevant for Bantu languages such as Mbugu since there is no grammatical rule that refers to plural or singular. In general there is little doubt for noun tokens whether they are singular or plural, as in Indo-European languages. Conversely, for any noun in a Bantu language there is little doubt whether they belong to class x or y; noun classes are not a category that is grammatically relevant in Indo-European languages.
