Two comprehension experiments were conducted to investigate whether young French-learning children (N = 76) are able to use a single number cue in subject-verb agreement contexts and match a visually dynamic scene with a corresponding verbal stimulus. Results from both preferential looking and pointing demonstrated significant comprehension in 30-month-olds with no preference for either singular or plural. These results challenge previous claims made on the basis of English and Spanish that comprehension of subject-verb agreement expressed as a bound morpheme is late, around 5 years of age (V. A. Johnson, J. G. de Villiers, & H. N. Seymour, 2005; A.-T. Perez-Leroux, 2005). Properties of the adult input were also analyzed. Possible implications for theories of syntactic acquisition are discussed.
