Representation vs derivation: The case for a modular view of phonology
Résumé
Plurilinear representations and constraint-based derivation have been the main tools used in the last 40 years by autosegmental approaches and OT respectively. It is argued here that the border be-tween representation and derivation depends on another key division in phonological theory: in phonology proper, there are no such things as processes involving feature propagation or delinking; only by virtue of morphophonological alternations, that is of phonology/morphosyntax interaction, may an object be said to changeinto another one. Thus, representational theories better describe core phonology, seen as an au-tonomous module of grammar, while constraint-based models are nec-essary to deal with computation associated with phonology's upper interfaces.
