犯 (fàn): This character means “to violate,” “to offend,” or “to attack.” The radical on the left, `犭` (quǎn), is the “animal” radical, often associated with dogs or beasts. This can give the impression of an unruly, untamed, or aggressive action that goes against established order.
法 (fǎ): This character means “law,” “rule,” or “method.” The radical on the left, `氵` (shuǐ), means “water.” Anciently, water symbolized fairness and levelness, as its surface is always flat. The right side, `去` (qù), means “to go.” Together, they suggest the established, fair standard that society “goes by.”
How they combine: The two characters form a very logical word: “to violate the law.” It's a clear and powerful combination that leaves no room for ambiguity.
