Second language acquisition has to integrate the totality of the SLA process, which includes both the learning of the core syntax of a language and the learning of the lexical items that have to be incorporated into that syntax. But these two domains involve different kinds of learning. Syntax is learnt through a process of implementing a particular set of universal structures, whereas the learning of lexis is characterised by the building up of associations (or connections). Yet these two systems must come together in the creation of a whole linguistic system in the mind of an individual. This book is designed to state the implications of these two paradigms in as clear a way as possible through examples of the research carried out within each paradigm and to examine how they can be made to inter-relate in a way which would enable us to explain better the overall process of SLA.

This book provides a critical review of recent theories of semantics-syntax correspondences and makes new proposals for constraints on semantic structure relevant to syntax. Data from several languages are presented which suggest that semantic structure in root morphemes is subject to parametric variation which has effect across a variety of verb classes, including locatives, unaccusatives, and psych verbs.The implications for first and second language acquisition are discussed. In particular, it is suggested that different parametric settings may lead to a learnability problem if adult learners do not retain access to sensitivity to underlying semantic organization and morphological differences between languages provided by Universal Grammar.An experiment with Chinese-speaking learners of English is presented which shows that learners initially transfer L1 semantic organization to the L2, but are able to retreat from overgeneralisations and achieve native-like grammars in this area.Suggestions for further research in this rapidly developing area of theory and acquisition research are also made.
