Abstract
Japanese boasts a great variety of tautological expressions, by which these tautologies fall into three categories indicated by particles, namely, ハ (pronounced wa), ガ (pronounced ga) and モ (pronounced mo). Some of which carry certain unusual semantic features when these tautologies are employed in clauses. This paper aims at analyzing the ハ (pronounced wa) tautology in subordinate clauses with minimal independence degree, and exploring the semantic properties of this category.
