| Abstract: | This article argues that counter-feeding opacity can be understood as a chain shift mapping and provides an account of chain shifts using contrast preservation theory (Lubowicz 2003). A case is examined that involves interaction between palatalization and spirantization in Polish (Rubach 1984). The central idea is that there exist constraints on contrast that can compel a phonological process. The key implication is that push shifts are admitted, unlike in previous approaches to opacity in OT (i.e., local conjunction, ternary scales, sympathy theory etc.). |
