grammatical innovations in expanded pidgins and creoles - linguistic universals, conventional language change, the influence of features of languages in the contact environment, or a mix of two or more factors? In addressing these issues, the author looks at research on processes of second language

acquisition and use, including simplification, overgeneralization, and language transfer. He shows how these processes can account for many of the characteristics of contact languages, and proposes linguistic and sociolinguistic constraints on their application in language contact. His analysis is supported with detailed examples and case studies from Pidgin Fijian, Melanesian Pidgin, Hawai'i Creole, New Caledonian Tayo and Australian Kriol, which he uses as well to assess the merits of

competing theories of language genesis. Professor Siegel also considers his research's wider implications for linguistic theory. -  less
