ABSTRACT
However, an innate knowledge that language is rule-governed, that it has a hierarchical structure, and that it makes use of structuredependent operations by no means explains the whole of language acquisition. We still need to know exactly how children develop language ability so efficiently. We would also like to find out why it is that English children follow such remarkably similar paths in the development of their language. These are mysteries which cannot just be swept aside with the vague explanation of ‘innate programming’. We must investigate the matter more fully.
