About
The character 效 is a phono-semantic compound. Its right component, 攵 (pū), depicting a hand holding a stick or the act of striking, provides the semantic category of action or exertion. The left component, 交 (jiāo), supplies the phonetic value. Its original meaning involved dedicating oneself or presenting something to a superior. This sense later expanded to include imitation and following a model. In modern usage, the character has broadened further to denote effectiveness, utility, or the results of an action, as seen in terms relating to efficiency and outcomes.
