to inform
📢 告 (tell) + げる (verb ending): to tell someone news, to inform
告 means announce or tell, as in 報告 (report). Tsugeru is the verb 'to inform' someone formally of something. Think 'tell the news' to link the kanji's meaning.
告 — ox 牛 (top) + mouth 口
Originally a pictograph showing an ox with something on its head, possibly a yoke or sacrificial marker, combined with 口 (mouth) to suggest announcing or reporting. The character came to mean 'to tell' or 'to announce,' as in making a formal declaration. Today it commonly appears in words like 告诉 (to tell) and 报告 (report).
