The Chinese word 吵闹 is a coordinated compound (并列结构) formed by combining two synonymous or semantically related characters: 吵 (chǎo), which primarily means "to make noise" or "to quarrel", and 闹 (nào), which carries meanings of "noisy", "lively", or "to stir up trouble". Both characters contribute the core concept of noise and disturbance, and when paired together, they reinforce and intensify each other to form a single word meaning "to make a racket", "to be noisy and quarrelsome", or simply "clamor". This combinatory process, where two elements of similar meaning merge to create a more vivid or comprehensive term, is a common morphological feature in Chinese vocabulary building.
