This work deals with an unsolved problem that cannot be tackled in any systematic way: the case of translation where a lexical element (e.g. a verb) of the source language corresponds to several lexical elements of the target language. The author offers a solution based on classes d’objets, a system introduced by G. Gross to describe the semantic features of nouns and verbs in natural languages. The author’s solution consists of setting up the classes d’objets both in the source language and the target language and then linking them.
