In this study, we analyze the kind of actions L1 and L2 speakers of Italian perform by prefacing their responsive turns with the discourse marker be’. As a baseline, the article begins with an analysis of how native speakers of Italian use be’. We then carry out a quantitative and a qualitative analysis of the use of be’ in a number of L2 learners at different proficiency levels from three data sets of different types of interactions between students and native speakers of Italian. In the qualitative analysis, we adopt a conversation analytic perspective. The results suggest that both native speakers and L2 speakers, at an intermediate to an advanced level, perform a variety of social actions by be’-prefacing their responsive turns.
