한국인 일본어 학습자의 추량표현 「そうだ・ようだ・みたいだ・らしい」의 습득연구 - 『多言語母語の日本語学習者横断コーパス(I-JAS)』를 분석 대상으로-

Abstract

In this paper, I analyse the data collected from the I-JAS corpus to reveal the process whereby the Korean learners of Japanese acquire the presumptive expressions sooda, yooda, mitaida, and rashii. The primary results are summed up as follows. Firstly, the presumptive expressions are extensively studied by the students at the intermediate level or above. Most intermediate students have acquired yooda, whilst most advanced students have acquired mitaida. On the other hand, sooda and rashii are not frequently used regardless of the proficiency levels of learners. Secondly, the presumptive expressions may be classified in terms of the orders in which the learners acquire them. As for sooda, the learners first acquire its visual-evidential use and then its presumptive use. As for yooda, the learners first acquire its presumptive use, followed by its ‘other’ use, its exemplification use, and its metaphorical use. As for mitaida, the learners first acquire its metaphorical use, followed by its exemplification use and its presumptive use. As for rashii, I detected differences in the acquisition of several presumptive functions in each form. Thirdly, each use is associated with its own formal patterns concerning, e.g., the syntactic category of its preceding element; these patterns, however, are not related to the proficiency levels of learners. Fourthly, the error rate of the presumptive expressions used by the Korean learners does not exceed 5%.
