Le Developpement Des Pronoms Relatifs Qui Et Que Dans L'Acquisition Du Français

It results from the analysis of our data that IL's are actually systematic even if they present a certain variability, due to the fact that they are systems under continuous evolution. Our learners' ILs are characterized by their own rules, rules which do not derive from the interference of the first language but rather from some general and abstract principles which can account for language learning in the most different situations. In particular from our data it results that, at least in earlier stages, semantic features play a more preponderant role than syntactic functions. Moreover IL's seem to be submitted to universal constraints similar to those proposed for natural languages (i.e. language universals such as the "Accessibility Hierarchy" by Keenan and Comrie).
