Rule Insertion
Robert Drury King · Language · 1973
The claim that Rule insertion—rule addition anywhere in the middle of a grammar—is a possible type of phonological change is considered and rejected. Some putative cases of Rule insertion are shown to reduce to rule re-orderings governed by revised constraints on re-ordering; others involve non-controversial rule addition prior to the phonetic rules of a grammar; remaining cases of apparent Rule insertion are the fictitious consequence of incorrect analyses. New phonological rules can be added at only one point: at the end of the phonological rules but prior to the low-level phonetic rules.
