動詞に接続する「ものだ」の意味と機能 -意味と機能の派生関係を中心に-

This paper analyzes the meanings and functions of “monoda” connected with a verb using derivative relationships. A lot of research were previously conducted about the "monoda" which shows a modal meaning by connecting to a verb. However, little research examined the transition from a concrete object to an abstraction by analyzing actual example sentences. In this paper, our goal is to describe the transition from a concrete object to a modality form in terms of continuity. The results can be summarized as follows. First, the abstraction transition from a concrete object can be summarized as follows. In the case of representing a concrete object, "monoda" refers mainly to nouns and has specificity. And if "monoda" expresses a work or a language, the meaning becomes a little abstract. Next, when the object pointed to by "monoda" is further abstracted, it represents institution, organization, and psychology. There is a case in which "monoda" continues to represent an action. Second, the transition to the form of modality can be divided into three types as follows: ① to express natures and naturally, ② to express obligation, and ③ to express surprise. In the case of transition to the modality form, the form of "monoda" is fixed and special meaning and functions are obtained. Especially when the transition represents ③ surprise, it is characteristically used together with an adverb and it generates a syntactic restriction. In conclusions, it is confirmed the transition from specific objects to the modality format, which is connected with a verb, and this transition also shows continuity.
