This paper explores the application and non-application of final /n/ deletion in Ghayeni Persian. In this dialect, final /n/ deletion is a productive phonological process whose application in different domains and environments is affected by several opaque counterbleeding and counterfeeding interactions as well as bleeding. This research presents new empirical data about these aspects which could be of general theoretical interest. It is also an attempt to make a contribution to current debate in phonological opacity. In so doing, it adopts Harmonic Serialism (HS) to accommodate counterbleeding opacity. It offers an analysis to survive a pitfall challenging HS in handling counterbleeding opacity in derived words. With regard to counterfeeding opacity, it adopts Parallel Optimality Theory (POT) using Local Constraint Conjunction (LCC). It discusses how POT and HS in particular could treat opaque interactions in Ghayeni dialect. In addition, this paper argues that a candidate which undergoes the same process twice in the same step could also be included in HS’s gradualness condition.
