The word 解除 is formed by combining two characters, each contributing its core meaning to create a new, unified concept. The first character, 解, carries the fundamental idea of "to untie", "to loosen", or "to release". The second, 除, conveys the sense of "to remove", "to eliminate", or "to get rid of". When merged, their actions logically sequence and reinforce one another: to first release or untie a binding (解), thereby leading to its full removal or dismissal (除). This results in the combined meaning of "to lift", "to dissolve", or "to relieve" something, like a contract, a state, or a burden, completely and effectively.
