Etymology Origin:
The word traces back to Latin insinuare ("to introduce by winding or bending"), combining in- (into) and sinus (curve). It originally described physical insertion (e.g., threading a needle) but evolved metaphorically to describe subtle, indirect communication—like "weaving" an idea into someone’s mind. This reflects the logic of迂回 (circuitous) persuasion.
