The Syntactic Flexibility of French Degree Adverbs Anne Abeillé and Danièle Godard While French degree words in French have been assigned several syntactic categories, we show that they are rather highy polymorphic adverbs (they occur in all syntactic domains), which select the expression they modify on a purely semantic basis. Like French adverbs in general, they occur both to the left and to the right of the head they modify. Following previous work (a.o. van Noord and Bouma 1994, Abeillé and Godard 1997, Bouma et al. 2000), we assign them two different grammatical functions, adjuncts and complements. Semantically, they differ from quantifiers. We follow Kennedy (2000) who analyzes them as scalar predicate modifiers. Finally, the specific syntactic constraints that characterize a subset of them can be shown to follow from, or be related to, their weight properties (Abeillé and Godard 2000). We conclude that their apparently idiosyncratic properties fit into a more general theory of grammar.
