The kanji 断 is a phono-semantic compound (形声文字). The left side is a radical called 斤 (kin), meaning "axe" or "hatchet," which represents the meaning element (semantic component), suggesting the act of cutting or severing. The right side is 㫁, which is the phonetic component, offering the pronunciation ダン (dan). Thus, the character combines a visual representation of the action of cutting with a phonetic clue for its pronunciation.
