Lee, Gyeong-ho. 2007. A Study on the Meaning of Korean Manner Adverb 'seulseul'. Korean Semantics, 23. This paper aims at determining the meanings of Korean manner adverb 'seulseul(슬슬)' and those distinctive environments, and also aims at establishing a method of analyzing manner adverbs. The methodological issues of this paper are divided into two types, namely structural and procedural types. In studying the first type, a matter of concern is concentrated on the relationship between syntactic structures and the distinctive environments of meanings in order to extract the meaning of adverb proper. Specially, in terms of paradigmatic and syntagmatic features of verbs, the distinctive environments of meanings are dealt with. In studying the second type, it is explained that the process of meaning analysis is achieved in terms of structural semantics. This process is performed through three steps: 1) to select meaning candidates, 2) to analyse the meanings with special reference to distinctive environments, 3) to establish the sememe. 'seulseul' is analyzed in terms of paradigmatic and syntagmatic features. The meanings of 'seulseul' are grouped into 'weakness-of-force, slow, covert' class, 'pain' class in terms of paradigmatic features. These two groups are attributed to two lexemes(namely, 'seulseul1', 'seulseul2') respectively. 'seulseul1' belongs to the 'weakness-of-force, slow, covert' class and has seven meanings which are distinguished by the paradigmatic feature and the selective features of its arguments.
