This paper presents a semantic interpretation of adjectival modification in terms of the Generative Lexicon. It highlights the elements which can be borrowed from the GL and develops limitations and extensions. We show how elements of the Qualia structure can be incorporated into semantic composition rules to make explicit the semantics of the combination adjective + noun. 1 Aims Investigations within the generative perspective aim at modelling, by means of a small number of rules, principles and constraints, linguistic phenomena at evel of abstraction, level which seems to be appropriate for research on multi-linguism and language learning. Among works within the generative perspective, one of the most innovative is the Generative Lexicon (GL) (Pustejovsky 91, 95) which introduces an abstract model opposed to sense enumeration lexicons. The GL is based (1) on the close cooperation of three lexical semantic structures: the argument structure, the aspectual structure and the Qualia str...
