"On les a toutes sur le bout de la langue … au figuré bien sûr !" . Les discours préfaciels des dictionnaires d’expressions et locutions françaises

[Autom. eng. transl.] This article aims to identify recurring themes in the prefacial discourses of seven phraseological dictionaries published in the second half of the 20th century and at the beginning of the 21st century. In order to establish a typology of themes, the results of recent studies carried out on the prefaces of general monolingual and bilingual dictionaries will be integrated with the phraseographic questions likely to appear in the corpus. The metalinguistic, metatextual, metadictionnary and metalexicographical reflections of the authors of these texts will be analyzed, as well as their writing style.
