Abstract and Keywords
So-called phonological ‘change’ is explained as generally due to non-convergent acquisition. Since acquisition leaves the source grammar intact, it is not appropriate to refer to it as ‘change.’ Since the acquirer has no direct access to the phonological properties of the source, the differences which arise do not depend directly upon that phonology. In this sense, ‘phonological change’ is not phonological. We explain the establishment of a ‘descent relationship’ between grammars and the role of phonetics and UG in non-convergent grammar construction with respect to phonologization, lexification, and related processes.
