Abstract
This study investigates whether second language (L2) speakers can pre-empt a first language (L1) property which involves uninterpretable features, such as resumption. The Interpretability Hypothesis predicts persistent L1 effects in L2 grammars because uninterpretable features resist resetting beyond some critical period (Tsimpli and Dimitrakopoulou 2007). Unlike English, Saudi Arabic allows grammatical resumption in complex wh-interrogatives, which is highly preferred with (D)iscourse-linked wh-forms (e. g..ayy-NP 'which-NP') but disallowed with non-D-linked ones (e. g. ?eef 'what'). The study was conducted with fifteen native English speakers and 34 (very)advanced Saudi Arabic L2 speakers of English with age of onset ( AO 1-13 years). In a bimodal, timed acceptability judgment task, their accuracy judgments of 32 (un)grammatical wh-interrogatives were tested. As predicted, results show that L2 speakers of very advanced levels inaccurately accepted resumption especially with D-linked wh-interrogatives. The results also show non-significant differences between AO 1-6 and 7-13 years in their rejection accuracy of resumption.
