Abstract

This longitudinal case study of a child learning Northern East Cree (NEC) (Algonquian; polysynthetic) focuses on the development of the passive construction and unaccusativity from 4;06- 5;10. The passive is acquired over three stages: (i) productive use of morphology and reliance on unanalyzed chunks; (ii) active analysis of the passive construction (errors, self-correction, passive-active alternations) and (iii) mastery of passive grammar marked by an increase in complexity. A set of intransitive verbs that can be unaccusative or unergative are also investigated, with a focus on causative alternations, the range of verbs used, and the development of morphological complexity in utterances, using a measure of Mean Length of Utterance by morpheme. There is an overall increase in grammatical and morphological complexity at 5;06, as expected in U-shaped development. These findings do not support nativist hypotheses that the ability to form passives and unaccusatives matures at a given age (Maturation Hypothesis).
