Abstract
The traditional approach to Niger-Congo gender systems conflates the number markers of nouns and the gender-number markers of adnominals and pronouns into a single category of ‘class markers’. Using Jóola Fóoñi as an illustration, this paper discusses several types of phenomena commonly found in these systems that are problematic for the traditional notion of noun class and support the necessity of a revision of the conceptual and terminological framework commonly used in the description of Niger-Congo gender systems.
