About
核 (hé) is a phono-semantic compound combining the meaning component 木 (mù) 'tree, wood' and the sound component 亥 (hài). Its original meaning was the pit, stone, or kernel inside a fruit, a sense closely tied to the wood radical. The meaning later broadened metaphorically to denote the essential core or nucleus of any object or concept, moving beyond its botanical origins. This extension led to its adoption in modern scientific terminology, where it refers to atomic nuclei (as in 原子核) and related fields such as nuclear energy and nuclear physics.
