达成
dáchéng · HSK 5
reach (an agreement)
🤝 达 = reach/arrive + 成 = become/accomplish → reach-accomplish
达 carries the sense of arriving or attaining; 成 means to become or complete. Together they mean reaching a result — most often used with agreements, deals, or goals being finalized (达成协议 = reach an agreement).
成 — 戊 (halberd/weapon) + 丁 (nail/man)
Originally a pictograph of a halberd or axe-like weapon, suggesting the act of completing a task by force. Over time it shifted from 'to subdue' to the broader meaning 'to accomplish' or 'to become'. The 丁 element inside also hints at the chéng sound.
