This talk aims at describing some of the negative constructions available in Martinican (creole, Martinique), identifying and classifying the morphemes involved in these negative constructions. Relying on narrations and descriptions produced by native speakers as well as elicitations, I consider first clausal negation (1). I look at negative predication in both main/independent and subordinate clauses. Two negative markers, pa and pé, are involved and present specific distributions accordind to the predicates. I also describe two temporal meanings that have specific markers in negative constructions : not yet and no more. Then, I describe how non clausal negation is expressed focusing on negative indefinites and negative quantifiers (2).
