The syntax/morphology interface in Spanish L2 acquisition: Focus on quantified DPs

Abstract

This article examines whether L2 acquisition of morphology and syntax develops independently (the Separation Hypothesis) or not (the Rich Agreement Hypothesis), focusing on the acquisition of Number specification on certain Spanish quantifiers by French speakers. In Spanish, some quantifiers are specified for Number and directly precede the head noun, in contrast to their French counterpartswhere a dummy preposition de must appear inside the DP. Results from a grammaticality judgement task and a production task show that intermediate and advanced learners perform poorly on plural inflection with some quantifiers, and reject the use of de. This suggests that they have acquired Number specification on these quantifiers, which allows Case marking on the following noun, but do not produce the appropriate morphology. These results support the Separation Hypothesis, but not the Rich Agreement Hypothesis.
