| Abstract: | An alleged defect in transformational treatment of syntax acquisition is the absence from child speech of certain predicted errors with ‘wh-’ constructions. In this paper, a theory of acquisition dynamics and intensive longitudinal data are brought to bear on this issue. The key observations involve an early precursor, at 24—28 months, of the relative clause. The analysis sheds light on two fundamental issues in transformational acquisition theory: The permissibility of simultaneous rule changes and whether a transformation can be acquired before the associated deep structure. The issues and analysis can be translated into non-transformational terms. |
