‘Geminate inalterability’ is the well-known phenomenon whereby a rule affecting singleton segments fails to alter comparable geminates. Past accounts have attributed inalterability to geminate-specific constraints on rule application. Two new generalizations point in a radically different direction. First, rules respecting inalterability are purely structure-filling (never structure-changing). Second, inalterability occurs also among singletons. We develop a new theory attributing inalterability to prespecification: geminate (and singleton) inalterability follows solely from the Elsewhere Condition. This explains not only the convergence of regular geminates and irregular singletons, but also the asymmetry among rule types sensitive to inalterability. Geminate-specific constraints on rule application are neither necessary nor sufficient to account for inalterability.
