About
秒 is a phono-semantic compound. Its left side, the semantic radical 禾, represents grain or crops. The right side, 少, means small or few and provides both phonetic value and a semantic hint of tininess. The original meaning referred to the fine, hair-like beard at the tip of an ear of grain, a minute biological detail. This sense of extreme smallness led to the character's adoption for minimal fractions of measurement, becoming the standard unit for a second in time and a second of arc in geometry.
