The kanji 裂 is a phono-semantic compound (形声文字, keisei moji). The left side is a radical representing "cloth" or "silk" (衣偏, koromo hen). The right side is a phonetic component, whose original form represented the action of splitting. The combination of the radical and phonetic component suggests the meaning of tearing or splitting cloth. Over time, the meaning broadened to apply to various objects and situations involving division or separation.
