This volume contains all 14 papers and three commentaries from the Recent Advances in the Generative Study of Second Language Acquisition Conference that was held in 1993 at MIT. Eleven of the papers address the acquisition of syntax. Of these, four focus on functional categories in second language (L2) acquisition. Vainikka and Young-Scholten propose that, although lexical categories or content phrases (NP, VP, AP, PP) transfer from the first language to the second, along with the headedness of those categories, functional categories or grammatical phrases (DP, IP, CP) do not. Using longitudinal data from Korean, Turkish, Italian, and Spanish learners of German, they suggest that learners begin by adopting a VP structure for the sentences in the L2 and then subsequently expand this into an underspecified finite phrase (FP), then an agreement phrase (AgrP), and finally a complementizer phrase (CP).
