From doing work on your own talk to doing work on others’ talk

Research on L2 interactional competence (IC) has become increasingly focused on how L2 speakers develop and recalibrate linguistic resources to do interactional work, i.e., how L2 speakers develop a grammar-for-interaction (Pekarek Doehler 2018). In this paper, I use interactional linguistics to track one L2 German speaker’s IC development over 11 months by analyzing her use of German also (English ‘so’) in formulations (see Deppermann 2011; Heritage & Watson 1979, 1980). In initial months, the L2 speaker uses also exclusively to do work on her own prior talk, e.g., in upshots, consequences, and unpackings. The L2 speaker’s initial also uses contribute to moves that maintain intersubjectivity by ensuring her co-interactant’s understanding of her own talk. In later months, the L2 speaker diversifies her uses of also, including uses oriented to co-interactants’ prior talk that address manifest problems of intersubjectivity: to preface an other-correction of an incorrect candidate understanding, and to preface turns addressing a co-interactant’s problem of understanding. The L2 speaker’s changing also uses demonstrate her ability to contribute to interactional organization in increasingly diverse ways, evidencing a developing grammar-for-interaction. I end by calling for more research on the L2 development of linguistic resources that primarily serve interactional functions, such as particles.
