This slender, neatly typeset volume contains a selection of the papers presented at an international three-day workshop on creole languages and language acquisition, held at the University of Leiden in 1990. Entitled “The logical problem of language acquisition,” the workshop set out to investigate the acquisition of parts of the grammar by children and adults. The purpose of the Leiden gathering was to bring together linguists from essentially two fields (language acquisition theory and pidgin/creole studies) in order to “solve the ‘logical problem of language acquisition’ from as many perspectives as possible” (p. 6).1 The central issue examined during the workshop was whether the specific circumstances of the genesis of a creole language have implications for theories of language acquisition in general. Conversely, the organizers and participants hoped that their discussions would shed new light on the early history of existing creole languages.
