The kanji 敗 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is a part called 攴 (bokukuri, usually written as 攴) which acts as a phonetic component that suggests "to tap", also meaning "to strike". The right side is 貝 (kai) meaning "shell", also representing "wealth". The original meaning of the character was "to take spoils", and was later developed to mean "to be defeated" or "failure". It originally associated with the stripping of wealth after a battle or a loss. The implication is that after the defeat, something is taken away from the defeated side, like wealth or possessions.
