This paper investigates the L2 acquisition of the morphosyntax of number agreement of French by L1 learners. The study is based on a pilot study that investigates learners’ knowledge of number agreement of two paradigms of subject-verb number agreement in French: the so-called matching paradigm in which agreement in number is expressed audibly via an alternation of the verb stem between a singular and plural forms and the mismatching paradigm in which the number agreement is not audible realized via singular vs. plural alternation. We discussed our sample’s proficiency in (de-)normalizing number agreement and the implications it has for the theory of corrective feedback and linguistic input in L2 processing in Language acquisition.
