The semantics of embedding predicates influence the acceptability of internally headed relative clauses in Korean

Abstract This study examines whether embedding predicates’ semantic type affects the acceptability of internally headed relative clauses (IHRCs) in Korean. Existing studies on Korean IHRCs have primarily focused on their highly limited distribution, employing three research approaches to understand their restricted use: (i) explaining their formal restrictions using a set of rules; (ii) describing how they are used with naturally occurring data; (iii) refuting their existence as an independent construction in Korean by providing alternative explanations for how the interpretation of IHRCs is construed. Although these approaches have significantly enhanced the understanding of the use of IHRCs in Korean, whether a specific semantic type of embedding predicates renders an IHRC construal in a more acceptable manner has not been explored. To address this research gap, we conducted an acceptability judgment task. The results showed significantly higher acceptability, compared to the control condition, for predicates implying physical contact between entities but not for those that do not. This finding may indicate that Korean IHRCs serve as an example of a partially productive or verb-class-specific construction. This study contributes to the understanding of partial productivity or local generalization in language use and the interaction between a human and an object.
