Divided into three main sections on Phonology, Syntax and Semantics, this new volume on variation in French aims to provide a snapshot of the state of sociolinguistic research inside and outside metropolitan France. From a diatopic perspective, varieties in France, Belgium, Switzerland, Africa and Canada are considered, mainly with respect to phonological features but also focusing on syntactic and lexical evolutions (the relative clause in Ivorian French and discourse markers in Canadian French). The acquisition of stylistic features of French figures in chapters on both first and second language learners and variation across different genres is addressed with respect to non-standard non-finite forms. Finally, a section on semantic change traces the way that interactional and other socio-historical factors affect word meaning.
