证据

Why does 证据 look like this?

证 (zhèng) consists of the 'speech' radical (讠) and 'upright/correct' (正). It suggests using speech to correct or verify something. 据 (jù) combines the 'hand' radical (扌) and 'squatting/house' (居), implying something you can grasp or rely on as a base. Together, they represent something spoken or held that points to the truth.
