The word 见证 is formed by combining two characters: 见 (jiàn), which means "to see" or "to witness", and 证 (zhèng), which means "proof" or "evidence". It is not merely a sum of its parts but a conceptual fusion where the act of seeing (见) is intrinsically linked to the establishment of truth or verification (证). The formation creates a holistic idea of an event or object that both is observed and itself serves as conclusive proof, encapsulating the moment where personal observation and objective evidence become one and the same.
