Although meetings are becoming more frequent in professional situations, participants are still poorly prepared in their training for this exchange format, which nevertheless directly conditions their work. If they are invited to a meeting, whatever their qualification or status, they encounter difficulties in understanding its content and in intervening, whether they are non-native speakers, native speakers with language insecurity or simply unfamiliar with meetings (beginners, professional retraining). Based on the analysis of meetings collected in situ in different contexts, we will present the key stages of a meeting and its organisation. We will identify the major potential difficulties and propose resources based on these real-life situations to prepare future participants to anticipate and master them to acquire the interactional skills that will enable them to better understand what is going on and to be able to intervene appropriately.
