The Chinese word 验证 is a compound formed by combining two semantically related characters: 验, meaning "to test" or "to examine", and 证, meaning "to prove" or "evidence". Together, they create a logical sequence where the act of testing or examining (验) is performed in order to obtain proof or confirmation (证). This structure follows a common pattern in Chinese word formation known as a resultative or purposive compound, where the first character denotes an action and the second character indicates the purpose or result of that action. Thus, 验证 comprehensively means "to verify" or "to validate", to examine something in order to confirm its truth or accuracy.
