Phraseology lies at the crossroads of many fields in the language sciences: syntax, semantics, pragmatics, contrastive linguistics, lexicography, NLP, cognitive linguistics, translation and, more recently, didactics and language acquisition. This strong interdisciplinarity reflects the great complexity of the field and its object of study (Mel'čuk 2023: 12). More recently, the perception of the field of phraseology has undergone a renewal in its research target. The great interdisciplinarity to which it is subject and the diversity of forms of its object of study are behind a recent extension of the field of phraseology (cf. Legallois and Tutin 2013), towards fields of study such as terminology, discourse analysis, interactional analysis, psychology, stylistics or AI technologies. This broadening has undeniably provided fertile ground for the emergence of a subfield of phraseology concerned with the link between <Forme↔︎Sens↔︎Fonctions> in interactional contexts: pragmatic phraseology. Among these prefabricated lexical elements found in interaction, the present symposium proposes to explore the pragmatic lexicon of interactions, i.e. lexical constructions with a particular communicative and actional function in oral or mediated interaction. These may include expressions such as discourse markers (you know, well, I see, like), ritual expressions (nice to meet you!, attention!), expressions of affect (what the hell!, are you kidding me ?), routines of oral scientific discourse (Given this arguments, Surprisingly enough) or situational phrases (it rains cats and dogs!, the writing on the wall!, cf. Klein and Lamiroy 2011). 

This international symposium is in line with the still undeveloped disciplinary field of pragmatic phraseology and aims to initiate discussion on the characterization of PLI through the encounter of researchers from different epistemological and methodological horizons. As the symposium is intended to be interdisciplinary, its theme may be approached from the angle of 3 major topics:

• Topic 1: Theoretical, descriptive, and applied linguistics and translatology 
• Topic 2: NLP, tool-based linguistics and AI
• Topic 3: Didactics, acquisition, and pedagogical engineering

All languages may be used in the research that will be presented during the event, but only French or English may be used for abstracts, presentations, or submitted papers. A handout in Japanese may be prepared for Japanese speakers, but this is at the discretion of each participant. On the theoretical side, any theory is welcome and need not strictly conform to the framework proposed in the call for contribution, which is indicative. The symposium will provide an ideal setting for dialogue between different theoretical and epistemic approaches. Similarly, on the methodological side, experimental and new approaches are welcome. 

This international symposium is, therefore, a unique opportunity to bring together international researchers working in this new research field, which we hope will pave the way for future research on PLI. We invite all researchers, doctoral students, teachers, research engineers, and language professionals to contribute to this symposium.
