韓日両言語における言語接触による否定副詞の文法化 －「결단코/결코」と「決して」に注目して－

초록

This paper examines the grammaticalization of the negative adverbs kyeltankho/ kyelkho and kessite ‘never’ in Korean and Japanese ​​from the viewpoint of language contact. In previous research, kyeltankho, kyelkho and kessite have been considered the same expression. However, this view requires modification. In fact, kyeltankho has undergone degrammaticalization from an NPI, unlike kyelkho and kessite in the modern languages. Specifically, until the middle of the 20th century, kyeltankho was more grammaticalized as an NPI than kyelkho, but since the middle of the 20th century, kyeltankho has undergone degrammaticalization from an NPI under pressure from kyelkho. In other words, kyeltankho has not progressed to Stage 3 as an NPI and has lost its grammatical features as an NPI. This paper argues that the main reason for this linguistic phenomenon is language contact with Japanese. This paper presents (i) the grammaticalization processes of kyeltankho and (ii) five pieces of evidence to support the above claims.
