The word "冤家" is formed by combining the character "冤", which denotes injustice, grievance, or enmity, with the character "家", which here functions to refer to a person or party involved. Together, they literally mean "enemy" or "foe", but the compound has evolved to also imply a contradictory relationship, such as a lover or sweetheart, where conflict and affection are intertwined, derived directly from the semantic contribution of each character.
