The purpose of this study is to examine the linguistic characteristics of the expression of ‘taste’ in online restaurant review texts. Although restaurant reviews are written language, they are highly spoken, and they are written in a horizontal relationship, both producers and consumers of information. Therefore, without being bound by existing norms, they write their own experiences as if they were speaking, and freely use various new words and expressions to vividly convey the subjective evaluation of taste. Therefore, examining the linguistic characteristics related to the taste of restaurant review texts can contribute to broadening the understanding of new genres and broadening the study of Korean vocabulary. There are a lot of new vocabulary used in restaurant reviews, including abbreviations, foreign languages, dialects and North Koreans, reiterative, compound words, vowels added or syllables repeated forms, and idioms. In addition, figurative expressions are actively used, and various taste expressions related to texture, coffee, and sweetness are used.
