conclusion:
 
 "This first analysis of Breton child data shows a clear progression through the nursery school years. The children have evolved from single phrase utterances to sophisticated structures. Transfer of grammatical structure from French to Breton appears to have contributed to the rapid development of the D-system in Breton. However over time the children have acquired the grammatical rules of Breton. One interesting aspect is their ability to use a variety of word orders in Breton. They do not restrict themselves to SVO as could have been expected since they are French first language speakers. There are instances of code-switching, but it appears to be a compensatory strategy the children resort to when in difficulty rather than the socially motivated code-switching of  confident bilinguals. There are a number of immature features in their utterances, nonetheless it is clearly apparent that they have mastered the main grammatical rules of the Breton language by the time they are ready to move into primary education."
