confirm
✅ 证实 = 证 (prove/certify) + 实 (real/solid) — prove it real
证 carries the 言 speech radical (a formal statement/testimony); 实 means real or substantive. Together: take a claim and back it with evidence so it stands as real — confirm or verify.
证 — speech radical 讠 + 正 (correct/upright)
证 is a semantic-phonetic compound. The speech radical 讠 (言) signals it relates to words or testimony, while 正 (zhèng, 'upright/correct') gives the sound and hints at 'verifying truth.' Originally written 證, it meant to testify or prove; today it means evidence, certificate, or to prove.
