||Choi, Kyung Ae & Joo, Dae Hwan. (2017). A study on resyllabification and palatalization in Korean. The Linguistic Association of Korea Journal, 25(4). 23-40. The purpose of this paper is to examine the phonological unit associated with phonological phenomena, emphasizing the vital role of resyllabification and ambisyllabicity in the word formation process to study palatalization in Korean in the framework of lexical phonology. By studying examples and counterexamples in similar phonological environments, we discover that the phonological word (Pw) is the unit in which resyllabification occurs in Korean. Another suggestion is that all words or phrases automatically go through a syllabification device (SD) whenever new word formation occurs in phonology in order for resyllabification to take place. To conclude, palatalization in Korean is a phonological phenomenon taking place in derived environment when the preceding coronal consonants share the feature of [+high] with the following sound by becoming an ambisyllabic element as a consequence of the resyllabification achieved by passing through the SD within the domain of the phonological word.
