🧠 认 (recognize) + 知 (know) = cognition: to recognize and know
认 — speech radical 讠 + 忍 rěn (phonetic)
认 is a semantic-phonetic compound: the speech radical 讠 (simplified from 言) signals meaning related to words or speaking, while 忍 rěn provides the sound. The traditional form 認 carried senses of 'acknowledge' or 'recognize through speech,' which extended to today's meanings of recognizing, identifying, and admitting.
