We show how idioms can be parsed in lexieal- ized TAGs. We rely on extensive studies of frozen phrases pursued at L.A.D.L) that show that id- ioms are pervasive in natural language and obey, generally speaking, the same morphological and syntactical patterns as 'free' structures. By id- iom we mean a structure in which some items are lexically frozen and have a semantics that is not compositional. We thus consider idioms of differ- ent syntactic categories : NP, S, adverbials, com- pound prepositions.. , in both English and French. In lexicalized TAGs, the same grammar is used for idioms as for 'free' sentences. We assign them regular syntactic structures while represent- ing them semantically as one non-compositional entry. Syntactic transformations and insertion of modifiers may thus app...
