In Chapter 5, the inner structure of clauses is investigated. It is noticeable that what kind of elements can be included in subordinate clauses depends not only on form but also on function and meaning. Conditional clauses are larger than manner clauses, and can include subject. And reason clauses, concessive clauses, opposite clauses are even larger, in this order, and become progressively similar to the structure of main clauses. Chapter 6 discusses the hierarchy among clauses.
Subordinate clauses differ according to what kind of subordinate clauses can be included mutually.
From this viewpoint, also, manner clause are the smallest, while opposite clauses are the most similar to main clauses. Chapter 7 describes the relationship between the structure of integrating sentences and mood and modality. In the hierarchy there are various strata. In conclusion, it is demonstrated that sentences in Korean form a hierarchy in the structure of proposition and modality. The purpose of the present paper is to describe the various structural characteristics of the adnominal clause in Modern Korean in reference to the same construction in Japanese.
