Quels rapports entre grammaire des constructions et phraséologie en didactique des langues vivantes ?

This article aims to present a didactic approach to learning idioms in the field of Teaching Modern Languages from the relationships between Phraseology and Grammar of Construction (CG). This approach seeks to show that a foreign language can be taught through its phraseological units. To do this, we will take as a starting point the idea of the mind map from D. Legallois (2014), who proposes a possible representation of the relationship between free and fixed constructions in the context of a Grammar of Constructions which considers language to be a directory of structures organized in a lattice. This proposal involves scenarios that we reformulate in order to turn them into didactic material. We will situate this mind map as part of the Phraseodidactics of French as a Foreign Language (FFL) in particular, to update the regularity of the underlying structures to phraseological units as postulated by the Grammar of Constructions (Fillmore, Kay et Connor 1988, Fillmore et Kay 1993 , Croft et Cruse 2004, Goldberg 1995, 1998, 2004).
