条件表現と原因理由表現の平行性とずれ

Abstract

Many previous studies have taken the view that conditional clauses and cause-reason clauses differ only in whether their propositions are hypothetical or factual, and that they share other characteristics in common. This paper shows that there are differences between the two clauses in terms of clause size, rewriting into two sentences, etc. This difference is not automatically derived from the hypothetical/factual difference between the two clauses, which indicates that the conditional clause and the cause-reason clause are not completely parallel.
