Editor Michel DeGraff provides us with a thought-provoking collection of studies that address topics involving language acquisition, creole formation, language change, and the connections between the three phenomena. One of the main goals of the volume is to arrive at a better understanding of the interaction between the “extraordinary external factors” surrounding the formation of pidgins and creoles and the “ordinary internal factors” involving U(niversal) G(rammar)–constrained language invention (p. 11), a UG-type repackaging of Thomason's ordinary-processes–extraordinary-results take on language mixture. The underlying theme DeGraff uses to connect the varied contributions is, in fact, UG: “This volume is seeking the right ‘version of universalist influence interpreted as constraints on the formal structure of creoles, in fact of natural language'” (p. 17). In characterizing the processes of pidginization and creolization, DeGraff chooses a narrow definition, that of the plantation situation (p. 2), thus disregarding interethnic pidgins and creoles (e.g., Hiri Motu and Tok Pisin in Papua New Guinea) and fort creoles (e.g., many of the Portuguese-based creoles). Although DeGraff does not point this out, he does mention other biases of the book: (a) it focuses only on morphosyntax from a generative UG-like focus; (b) it largely neglects variationist and quantitative approaches; (c) it does not explore the connection between UG and all-purpose cognitive structures (except Newport; see below); and (d) it considers only a subset of creoles that emerged from contact with European colonizers.
