The study aims to identify significant features and cultural differences of fear-related vocabulary in Chinese and Korean language through contrastive analysis. As a consequence, it is revealed that words for fear are mainly included in psychological verbs, and that there is a great deal of replacing members in the semantic field. Also, these types show clear tendencies towards bisyllabification. In Korean, by contrast, most of the words denoting fear fall into the category of verb, the rest of which, on the other hand, consist of nouns or adjectives. Their members are included in either Korean native words or hybrid ones formed as ‘Chinese character and Korean language’. Then, fear-related idioms, too, are contrastively analyzed in Chinese and Korean, and the analytic outcomes are as follows: there are innumerable idioms based on metonymy and metaphor, and meanwhile, they have a great deal in common, yet with several differences in both languages.
