This study investigates the syntactic structure of the adverbial clause on the 'nə-gi-da' appearing in the new-style novel in the early 20th century. Its main issues and outcomes are summarized as follows: First, this study is conducted with the target of the new-style novel because its related precedent study only targeted 『Daehanmaeilsinbo』 published at the beginning of the 20th century, which endowed a possibility that the language at that time was not fully reflected. Second, in the study, the syntactic structure of the adverbial clause is examined according to the five types classified. It is proven that among the five types, [1] type and [2] type are realized as 125 cases (41%) and 128 cases (42%) respectively. To the next, [4] type is discovered in 43 cases (14%), followed by [5] type in 5 cases. [3] type is identified only with one usage. Third, the outcomes are actually different from those of 『Daehanmaeilsinbo』. In the new-style novel, [1] type and [2] type appear having competitively similar figures even though [2] type slightly predominates, whereas [1] type occupies an overwhelming proportion in 『Daehanmaeilsinbo』. These differences are due to the characteristics that feature the newspaper and the novel. [1] type seems to be a more suitable structure to the medium of a newspaper whose purpose is to convey information clearly since its structure is the one in which the original characteristics of 'nə-gi-da', namely, requiring an object, is explicitly revealed. However, [2] type seems to be used more naturally in the new-style novel which actively reflects the spoken expressions in everyday life because [2] type is a structure reflecting psychological language use of the public who prefer to omit the language elements that can be found in the context or can be identified as the same and express them economically. Fourth, 'judgment adjectives', 'feeling adjectives', and 'psychological verbs' can be substituted to the predicates of the adverbial clause. It was found that 'feeling adjectives' was used more than half with the domination of 59%, and 'judgment adjectives' was followed by 37%. 2 kinds of 'psychological verbs' were found in the 17th century, 3 in the 18th century, 6 in the 19th century and 23 in 『Daehanmaeilsinbo』. However, only 4(4 percent) are found in this study. This is also due to the literature feature. Speaking of newspapers, the media is open to new vocabulary that contains a changing social phenomenon, while novels are conservative in terms of new vocabulary inflow since novels usually highlight spoken expressions of everyday life.
