115 Reviews Issues in Applied Linguistics Vol.1 No. 1 It could turn out, then, that while perhaps crucial in some respects, U G may not have much to say about some of the things which give L2 learners headaches and which language textbooks devote so much of their space to: inflectional paradigms, vocabulary (and lexical subcategorization) and language-idiosyncratic elements, such as articles in English or formal vs. informal discourse levels in Japanese. UG, as a computational system, may facilitate the relative ease of interpretation (i.e., computing ) of anaphoric relations, for example, but it may be hard-pressed to aid in the acquisition of 3rd- person-singular -s in English, a process which may rely instead on some other learning mechanism (that apparently deteriorates with increasing age!). The importance of L 2 data may thus lie in contributing, along with data from L I and neurolinguistic studies, both to a more correct description of the various levels or components of U G and their interaction as well as to delimiting the scope of UG. One of the most important contributions of this book is the introduction's rather neat delineation not only of a set of minimal requirements for a theory of second language acquisition, but also of a set of questions and issues to be addressed in future research - the right set of questions at the right level of analysis (p. 18) -¬ which the editors have distilled from the papers collected in the volume. This convergence of ideas constitutes a kind of L2 critical mass which may well ensure that many of the questions raised in this volume will set the research agenda for second language acquisition in the foreseeable future. As such it certainly establishes the book as a basic reference text for theoretical issues in second language acquisition. Clahsen, H. (1989).

Clahsen has since modified his position somewhat, arguing that L2 learners do have access to principles of UG only insofar as these principles have instantiations in the speakers' native language (Clahsen, 1989, p. 12)..
