The kanji 秒 is a phono-semantic compound (形声文字). ⚫︎ The left side, 禾 (kome), originally meant "grain" or "rice plant". In this context, it acts as the semantic component, hinting at the association with something small or fine. ⚫︎ The right side, 少 (shou), means "few" or "little" and acts as the phonetic component, indicating the sound (though the sound has evolved over time). It implies the idea of a small amount, hence "second," which is a small unit of time. The combination therefore suggests a very small unit of time, related to the idea of a grain of rice as a tiny element.
