This paper investigates how Korean learners of English produce coronal stop-lateral sequences in words like potluck and padlock, explores what factors can have an effect on their production, and gives a constraint-based account of L2 phonological variations. The main findings are that Korean learners of English transferred coronal stop lateralization, thus turning English coronal stop-lateral sequences to lateral-lateral ones. Vowel epenthesis also occurred. This is attributed to Korean phonological system in which a stop is assumed to appear syllable-initially if it is voiced. Voicing and gender played a role in coronal stop lateralization, and voicing and word boundary had significant effects on vowel epenthesis. These L2 variations could be accounted for by using Davis and Shin (1999)’s constraints and Park (2006)’s *V[-pal, -lab, -low], and by taking up the idea of floating constraints that produce the variable rankings apparent in L2 phonology.
