This volume treats the connection between syntax and morphology with a focus on L2 acquisition. This interface has been a matter of considerable interest in theoretical circles ever since Chomsky (1994) and others argued that morphological parameters form the primary locus of cross-linguistic variation. As might be expected, generative theorists working in the area of language acquisition have responded to this argument with various analyses. L2 research is no exception: A variety of researchers have begun serious explorations on the ways in which morphology may (or may not) trigger variation not only in syntax, but also in argument structure. The volume thus brings together a concentrated research effort on the topic from an L2 perspective. The volume starts off with a comprehensive introduction to the various sub-topics and ends with an extensive index.
