I. I. In a paper dealing with the analogical elimination of allomorphy and the explanatory (in)adequacy of generative phonology in accounting for it, Hogg hypothesized that ‘a necessary condition for analogical change is that the alternation which is subject to the analogy must not be synchronically rule-governed’ (1979: 58). This observation was elevated to the status of a principle which was formulated as follows:
Analogical extension or levelling of some phonological rule can take place only if that rule is no longer present in the synchronic grammar of the language (Hogg, 1979: 8).
