This work is based on an investigation of language acquisition process, particularly in regard to syntax, among Mauritian children learning to speak Mauritian Creole as their first language. As such, it is the first major study of the development of child grammar in a Creole context. Mauritian Creole, in common with many Creole languages, emerged under extreme conditions and, as an isolating language, Mauritian Creole is typologically different from languages where syntax is predominantly tied to morphology.
