The word 试验 is formed by combining two characters whose individual meanings conceptually sequence and complement each other to create a new, unified idea. The first character, 试 (shì), carries the core meaning of "to try" or "to attempt". It is joined with the second character, 验 (yàn), which means "to examine" or "to verify". Together, they are not merely a sum of parts but describe a complete process: the act of trying something out (试) for the explicit purpose of then inspecting and evaluating its results or effects (验), thus forming the integrated concept of an "experiment" or "trial".
