Components

radical

讠 yán

speech; words (radical form)

Speech radical, simplified left-side form of 言. To prove or testify is to put something in words, so 证 sits in the speech-act family with 说 say, 论 discuss, 议 deliberate, 谋 plan, 课 lesson.

phonetic

正 zhèng

upright; correct

Phonetic — 正 zhèng directly supplies the sound for 证 zhèng. 正 also contributes a strong semantic resonance: testimony must be 'upright / correct'. Together: 'words that are upright' = proof, evidence, certificate. The traditional form 證 used 登 instead, but the simplified borrows 正's neat sound match.
