Usage Notes

验证 is closely tied to the empirical method and is fundamental in scientific, technological, and academic discourse. It differs from 证明 (zhèngmíng), which means to prove (often through logic or argument), in that 验证 specifically implies testing or empirical confirmation. 验证 is often the step that follows a hypothesis (假设): you propose a hypothesis and then verify it.

In technology contexts, 验证 is used for validation and verification in software engineering (功能验证, 验证码). In everyday life, 身份验证 (identity verification) and 验证码 (verification code/CAPTCHA) are common uses. The past form 经过验证 (proven, validated) functions as a modifier: 经过验证的方法 (a validated method).

Memory Hook

验 (to test, to inspect) + 证 (to prove, evidence): "testing something and obtaining proof" — empirical confirmation.
