to inform
📢 tōng (through) + bào (report) = a report that goes through to everyone
Think of it as a broadcast report — information that passes through channels to reach all recipients. Used for official circulars and formal notifications.
通 — 辵 (辶) walk + 甬 yǒng (phonetic)
通 is a semantic-phonetic compound. The 辶 (chuò) component means 'walk' or 'movement', giving the meaning of going through or passing. 甬 (yǒng), originally depicting a hanging bell or a path, supplies the sound. Together they convey 'to pass through, communicate, connect'.
报 — hand 扌 (报) + 卩 seal/kneeling figure
Originally 報 depicted a hand pressing a kneeling criminal under a manacle (幸 + 卩 + 又), meaning 'to judge' or 'requite a crime.' From 'repay/requite' it broadened to 'respond, report, announce.' The simplified form 报 keeps the hand 扌 and 卩 but drops the manacle element.
