This study revisits prosodic phrasing in North Kyungsang Korean (NK), focusing on intonational phrase (I-phrase). Based on the observation in Kim (1988) that a boundary low tone appears at the right edge of I-phrase, the present study shows in a constraint-based framework that I-phrasing is recursive and that the interaction of markedness and faithfulness constraints leads to a better description of I-phrasing in NK. Match Clause constraints (Selkirk 2011), faithfulness constraints, are employed to show the direct relation between surface syntactic clause edges and I-phrase edges. Even though it defies Non-Recursivity of the Strict Layer Hypothesis (Selkirk 1984, 1966), Equal Sisters constraint (Myrberg 2013), a markedness constraint, is shown to resolve the mismatch between syntactic and prosodic constituent edges by demanding the same prosodic category among prosodic sisters. Also shown here is that recursive I-phrasing is due to the ranking of Equal Sisters above Match Clause constraints. We provide one more piece of evidence for recursive prosodic phrasing by showing how I-phrases are formed in NK.
