The word 身亡 is formed by combining two characters that each contribute a essential layer of meaning to create a single, vivid concept. The first character, 身, means "body" or "the self", establishing the physical or personal subject. The second character, 亡, means "to perish", "to flee", or "to be lost", conveying a state of irreversible cessation or disappearance. Together, they forge a metaphorical whole where the perishable fate (亡) is directly and inseparably applied to the very essence of the living being (身), resulting in a concrete yet dignified expression for death, picturing the complete and final loss of the physical self.
