This is a new contribution to a theory of reiteration in natural languages, with a special focus on creoles. Reiteration is meant to denote any situation where the same form occurs (at least) twice within the boundaries of some linguistic domain. By including two case studies bearing on Hebrew and Breton alongside five chapters on creole languages (Surinam creole, Haitian, Mauritian, Sao Tome and Pitchi), this volume brings counter-evidence to the claim that reiteration phenomena are particularly typical of creoles. And by exploring the syntax of reiteration alongside its morphology, the authors are led to challenge the 'iconic' theory of 'reduplication' proposed in several other studies of similar phenomena. This volume will be relevant for creole studies, but also for readers more generally interested in language universals and the architecture of grammars.
