The word 非法 is formed by directly combining two conceptual building blocks: the character 非, which carries the inherent meaning of "not" or "to be against", with the character 法, which represents the core concept of "law" or "legal principle". Their union does not describe an action but instead creates a single, fused idea, the state or quality of being "not-law" or "against the law", resulting in the meaning "illegal" or "unlawful". It is a conceptual compound where the first element negates the fundamental concept of the second.
