7 Conclusion
</SectionTitle>
    <Paragraph position="0"> We have shown how idioms can be processed in lexicalized TAGs. We can access simultaneously frozen elements at different levels of depths where CFGs would either have to flatten the idiomatic structure (and lose the possibility of regular insertion of modifiers) or to use specific devices to check the presence of an idiom. We can also put sentential idioms in the same grammar as free sentences. The two pass parsing strategy we use combining with an operation of direct attachment of lexical items in idiomatic trees, enables us to cut down the number of idiomatic trees that the parser takes as possible candidates. We easily get possibly idiomatic and literal reading for a given sentence. The only distinctive property of idioms is the non-compositional semantics of their frozen constituents. The extended domain of locality of TAGs allows the two problems of internal discontinuity and of unbounded interpositions to be handled in a nice way.</Paragraph>
