This study aims to understand the meaning and function of degree adverbs. There has been no reasonable basis to set up the list of degree adverbs. It means that there is a lack of understanding the meaning and function of these categories. Degree adverbs must be used as a term that indicates adverbs with the semantic feature ‘degree’: It is intra-lexical distinctive, multivalent, and a kind of relative concept. It necessarily accompanies ‘norms of judgment’ and also grade ‘degree scales’. The degree adverbs that this paper has treated such as maeu, mucheok, gajang, etc. do not have ‘degree’. Therefore, these are not appropriate to have the name like degree adverbs. We need to use more appropriate degree adverbs than the existing terms and it depends on their meanings and functions.
