||Choi, Jeong-A & Lee, Yae-Sheik. (2018). An analysis of Korean English learners acquisition of the definite article co-occurring with proper nouns. The Linguistic Association of Korea Journal, 26(4), 245-266. The present study aims to show whether Korean students acquisition of the co-occurring with proper nouns is influenced by their familiarity with such definite article usage. To achieve this aim, the current study conducted two questionnaires. The first one was administered to 111 Korean students (41 middle school, 49 high school, and 21 college) in order to determine the degree of their English article acquisition; the second one to 55 college-level Korean English learners to evaluate the relationship between the learners familiarity with usage of the definite article with proper nouns and the degree of their acquisition. The results from the second questionnaire confirm a meaningful correlation between the college students acquisition of definite article usage with proper nouns and their familiarity with such usage. Furthermore, the presence or absence of a specific rule constraining the occurrence of the definite article with proper nouns does not affect the subjects' scores on the usage questions. These findings suggest that the Korean EFL learners in this study do not have enough exposure to instances where the definite article co-occurs with proper nouns for specific rules to influence their scores on the usage questions.
