Abstract
This study aims to examine the grammatical constructions associated with the frequent substitution of the nominative particle (-i/-ka) by the accusative particle (-ul/-lul) made by English L1-KFL learners and provide a strategy for the facilitation of Korean language learning and pedagogical improvement. The study explores the sentential constructions that ‘trigger’ such substitutions and attempts to give linguistic and pedagogical explanations. As a pedagogical strategy, the study proposes to use Korean-oriented English sentence constructions such as ‘As for X+Top/Nom, Y+Nom Z-Predicate’.
