A Study of Part-of-Speech Category Conversion in Korean Verbs - Focusing on Metonymy and Metaphor Mechanism.

This paper examines the phenomenon of part-of-speech conversions in Korean verbs and explores the mechanisms by which they occur. In Korean, some intransitive verbs are used like adjective verbs and some adjective verbs are used like intransitive verbs. In addition, some verbs have both intransitive and transitive forms(transitiveintransitive alternating verb or middle verb). These phenomena can be explained consistently with the concepts of metonymy and metaphor in cognitive linguistics.In Korean, 'jamijida(재미지다)' and 'pusida(부시다)' are adjectives that are also used as verbs, and 'jaminade(재미나다)' and 'matta(맞다)' are verbs that are also used as adjectives. 'usgida(웃기다)' and 'tuigida(튀기다)' are causative verbs, but they are also used as intransitive verbs and state verbs. The mechanism by which this happens can be explained by the phenomenon of metonymy, where 'the effect represents the process (cause)' and 'the process (cause) represents the effect', and another phenomenon of metonymy, where 'the whole represents the part'.
