公认

publicly known
📢 公认 = 公 (public) + 认 (recognize/acknowledge)
公 carries the sense of public or communal; 认 means to recognize or acknowledge. Together they mean something the public acknowledges — i.e. widely accepted or publicly known.
公 — eight 八 + private 厶
Originally an ideograph showing 八 (to divide) over 厶 (private/self), depicting the act of splitting away from selfish interest. The combination came to mean 'public' or 'fair,' the opposite of private. It later extended to senses like 'duke,' 'lord,' and 'grandfather.'
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.
