Bücher von Ian Roberts

This thought-provoking book offers an accessible introduction to the main discoveries and theories about the nature and wonder of language. It is aimed at general readers and undergraduates who are curious about linguistics and language. Purposefully written in a lively and direct style, technical terms are carefully introduced and explained.

Parametric variation in linguistic theory refers to the systematic grammatical variation permitted by the human language faculty. Although still widely assumed, the parametric theory of variation has in recent years been subject to re-evaluation and critique. The Null Subject Parameter, which determines among other things whether or not a language allows the suppression of subject pronouns, is one of the best-known and most widely discussed examples of a parameter. Nevertheless its status in current syntactic theory is highly controversial. This book is a defence of the parametric approach to linguistic variation, set within the framework of the Minimalist Program. It discusses syntactic variation in the light of recent developments in linguistic theory, focusing on issues such as the formal nature of minimalist parameters, the typology of null-subject language systems and the way in which parametric choices can be seen to underlie the synchronic and diachronic patterns observed in natural languages.

The phenomenon of grammaticalization - the historical process whereby new grammatical material is created - has attracted a great deal of attention within linguistics. This is an attempt to provide a general account of this phenomenon in terms of a formal theory of syntax. Using Chomsky's Minimalist Program for linguistic theory, Roberts and Roussou show how this approach gives rise to a number of important conceptual and theoretical issues concerning the nature of functional categories and the form of parameters, as well as the relation of both of these to language change. Drawing on examples from a wide range of languages, they construct a general account of grammaticalization with implications for linguistic theory and language acquisition.
