injure, harm, remnant

殘 is composed of 歹 (cracked skull) and 戔 (small). 歹 depicts a cracked skull, implying harm or death, while 戔 is a pictograph of two long-handled weapons, also signifying harm or destruction. Both characters convey the idea of damage or ruin. Additionally, when an object is damaged, it becomes incomplete, so 殘 also carries the meaning of remaining or remnant parts.
