To account for the semi-free word order of French, Unification Categorial Grammar is extended in two ways. First, verbal valencies are contained in a set rather than in a list. Second, type-raised NP's are described as two-sided functors. The new framework does not overgenerate ., it accepts all and only the sentences which are grammatical. This follows partly from the elimination of false lexical ambiguities - ., ambiguities introduced in order to account for all the possible positions a word can be in within a sentence and partly from a system of features constraining the possible combinations. . | FRENCH ORDER WITHOUT ORDER Gabriel G.

INTRODUCTION In the version of categorial grammar henceforth CG developed by Bar-Hillel Bar-Hillel 1953 categories encode both constituency and linear precedence. Linear precedence is encoded by a ordering valencies in a list and b using directional slashes indicating whether the argument is to be found to the left or to the right of the functor. A similar approach is adopted in Unification Categorial Grammar UCG Zeevat Klein and Calder 1987 as regards word order whereby the directional slash is replaced by a binary Order feature with value pre or post. Thus S NIANP in normal CG translates as S NP pre NP post in UCG whereprg indicates thatthe functor must precede the argument and post that it should follow it. Our work on French syntax supports the claim that thecomplicated pattern of French linearity phenomena can be freated in a framework closely related to UCG but which departs from it in two ways. First there is no rigid assignment of an order value pre or post to verb valencies. Second following Gunji 1986 verbal valencies are
