The Acquisition of Noun Class Morphology in Eegimaa: Early Signs of System Building
Year: 2025
Type: article
Study design: Observational Study
Abstract: In this paper, we examine young children’s acquisition of the prefixal noun class system of Eegimaa, a Jóola language spoken in Senegal (Atlantic family, Niger-Congo). The analysis is based on spontaneous, spoken data representing a mixed design (longitudinal and cross-sectional), with –9.5 hr of recordings, including nine children, aged between 1;10 and 3;2. The data yielded 967 spontaneously produced noun tokens. Across the group of children, accuracy is already high at age 2 years, at 73%, and increases to 94% by age 3. Two children’s productions are examined more closely through a series of longitudinal recordings, which show that the majority of nouns are produced accurately, with target-like noun class prefixes already present from the earliest ages, a finding that differs from earlier research on the distantly related Bantu languages. Non-target-like nouns, produced with omitted, substituted or filler prefixes, amount to less than one fifth of the overall noun tokens produced in the transcribed recordings. We discuss the types of errors made by the children and possible reasons for them, and the implications of the learning trajectories for understanding morphological acquisition.
