The purpose of this study is to examine how hedging expressions in terms of lexicon and syntactic structure were presented in English listening test of Korean CSAT as a pragmatic strategy for Korean learners. To achieve this purpose, two questions were raised: Based on English listening test of Korean CSAT, 1) how do hedging expressions appear in terms of lexical structure? and 2) how do hedging expressions appear in terms of syntactic structure? In order to answer the research questions, the items of listening test from 1994 to 2022 were divided into two groups, the monologue and dialogue to figure out differences of their phonetic properties according to Nunan(1991)'s classification. Also, Crompton(1997) and Kim(2008)'s taxonomy of hedges were used because they defined hedging expressions as a pragmatic strategy. This study was analyzed by the corpus program, Antconc. The results indicated that hedging expressions used in the listening test in Korean CSAT appear depending on given taxonomy of hedges differently. First, the lexical hedging expressions were used more frequently than syntactic ones. In addition, these hedging expressions used in the listening test in Korean CAST appear depending on the type of linguistic data differently. Second, the rate of all syntactical hedging expressions in the monologues was approximately six times higher than in the dialogues. Some syntactical hedging expressions also have different meanings depending on the type of linguistic data, even if they are the same forms. More detailed accounts for analyzing are discussed in the paper.
