Since children are typically exposed to colloquial varieties, the primary linguistic data can lack properties of formal varieties during early years. If, however, the acquisition of a given property is delayed until age 5 or later, the acquired knowledge may rather resemble that of L2 learners.This happens in the acquisition of French interrogatives where certain inversion constructions do not occur in Colloquial French. Native speakers acquire them after the age of 5, and they behave like L2 learners in using or judging them. A grammaticality judgment test reveals a broad range of variability in their ratings of constructions which are ungrammatical in Standard French. Their grammar is afflicted by the kind of persistent optionality familiar from L2 acquisition.", }
