核

• Pinyin: hé
• Desglose de hanzi: 核 = 木 (wood/tree radical) + 亥 (phonetic; 12th Earthly Branch)

Significado

núcleo; parte esencial; (prefijo) nuclear

As a standalone morpheme and word, 核 encompasses the literal sense of a seed or fruit stone, the biological nucleus of a cell, the nucleus of an atom (hence 核能, 核武器), and the figurative core of a system, argument, or leadership structure (核心). Its versatility makes it one of the most productive morphemes in modern Chinese scientific and political vocabulary.
