The Chinese word **疑虑 (yílǜ)**, meaning "misgivings" or "doubts and worries," is a **synonym compound (并列式复合词)** formed by combining two semantically related characters: **疑 (yí)**, which means "to doubt" or "to suspect," and **虑 (lǜ)**, which means "to worry" or "anxiety." Each character contributes a distinct yet complementary aspect of meaning—**疑** emphasizes the cognitive aspect of uncertainty and suspicion, while **虑** adds the emotional dimension of concern and apprehension. Together, they merge to create a single, nuanced concept that encapsulates a state of hesitant uncertainty, where doubt and anxiety are intertwined, making the compound's meaning more comprehensive than either character alone. This formation is a classic example of how Chinese compounds semantically reinforce and refine an abstract idea.
