Flexible Syntax: A Theory of Case and Arguments (1999)

Most linguistic theories assume that each grammatical relation is established in a unique structural configuration. Neeleman and Weerman take issue with this view, arguing for a more flexible approach on the basis of conceptual considerations and data taken mostly, but not exclusively, from the Germanic languages. In-depth analyses of word order phenomena as well as diachronic and typological generalizations motivate a re-evaluation of the role of case in the projection of arguments. Case is shown to provide a syntactic foothold for thematic interpretation, something which is necessary in a grammar that does not allow fixed theta-positions. Thus, this study does not only offer a genuine alternative to many standard assumptions, it also explains why there should be such a thing as case in natural language.
