The status of the auxiliary do in L1 and L2 English negative clauses

Abstract

This paper addresses the issue of whether negative sentences containing auxiliary do in L1 and L2 English share the same underlying syntactic representation. To this end, I compare the negative sentences produced by 77 bilingual (Spanish/Basque)L2 learners of English with the corresponding data available for L1 acquirers reported on in Schütze (Carson, The status of he/she don't and theories of root infinitives, 2001), under the assumption that L1 and L2 grammars may be underspecified for Tense and/or Agreement features. I conclude that, despite similarities in the type of errors children and L2 learners produce, the L2 data do not show evidence of underspecification. Rather, it appears that L2 learners use a lexical strategy whereby they adopt don't as an independent preverbal negative marker.
