The Lexicon-Grammar, first developed at LADL (Laboratoire d’Automatique Documentaire et Linguistique, CNRS) by Maurice Gross and his team, is organised in a series of tables. Each table groups lexical items with related behaviour (in the structure of basic sentences, in the distribution of arguments, in terms of semantics). Each table includes a set of properties (in columns) and a flag of “+” and “−” indicating whether or not the item has this property. Part of these properties concerns nouns (called V-n) morphologically related to a verb, (chanter/chanteur/chant/chanson) and their semantic interpretation. This article focuses on verbal constructions (about 5,000 verbs have been examined) and various syntactic positions that deverbal nouns could occupy in these different constructions.
