There has been a great deal of discussion in the literature on second-language acquisition about the relationship between first-(L1) and second-language (L2) acquisition. I believe that the dust is beginning to settle and that it is now possible to move beyond this debate. I would like to do so in this paper, and examine in particular the role of linguistic input in L1 and L2 and the nature of conversational strategies in both processes.
