L2 discourse marker use in interaction: The case of pues in Spanish

While discourse markers (DMs) are crucial for coherence and interactional competence, previous research suggests that learners' usage of DMs differs from L1 speakers. Prior research has taken either a discourse-functional or interactional approach, yet combining these two methods may provide greater understanding of the unique learner communicative needs that drive the acquisition and use of DMs. This investigation contributes to research on interlanguage DM use by quantitatively investigating the frequency and functional distribution of the Spanish DM pues by L2 and L1 speakers of Spanish from a discourse-functional perspective and qualitatively examining pues as an interactional resource. Oral interviews with 58 L2 and 14 L1 speakers of Spanish were analyzed, revealing distinct frequency and distributional patterns across groups and unique L2 interactional needs that are supported with the DM pues. Results inform L2 learners and teachers of the importance of DMs for interactions and provide classroom implications.
