A Study of the Case Marking of English Speaking Learners of Korean in Complements and Adjuncts


 This study investigates the case marking of English speaking learners of Korean. In order to identify the linguistic contexts of case marking, I have subcategorized case marking into six types: accusative, case alternation, case alternation and stacking, case stacking, oblique case, and adjunct. The number of participants was 60 in total, 30 Korean native speakers (NK) and 30 English speaking learners of Korean (EK). The research questions of the study are: RQ 1. Do NK and EK show different grammatical judgments on Korean case marking according to the case marking types? and RQ 2. Is there proficiency variation among EK in grammatical judgment on Korean case marking? The independent t-tests have been conducted to answer the RQs. The findings of the study are: 1) ÈK fell short in accuracy and diversity of case marking in most of the complements when they were compared to their counterpart NK, and 2) there was not much difference in terms of language proficiency, except in the case stacking type. Based on the analyses, we argue that EK had not fully acquired case marking in most of the complements regardless of their language proficiency and were not able to utilize the function of case alternation.
