The Chinese word **紊乱** (wěnluàn) is a compound formed through the combination of two synonymous characters to reinforce a single concept. The first character, **紊** (wěn), originally depicted tangled silk threads and carries the meaning of "disorder" or "confusion," particularly within a system or sequence. The second character, **乱** (luàn), means "chaos," "disorder," or "mess." When paired, they create a tautological compound where both elements contribute the same core idea of disorder, resulting in a word that emphasizes a state of being **disordered, chaotic, or out of proper order**, often used in medical, systematic, or abstract contexts (e.g., 功能紊乱, functional disorder). This formation exemplifies a common pattern in Chinese vocabulary where near-synonyms are combined to solidify and specify a meaning.
