说干就干

Talk to dry
🗣️⚡ 说 say + 干 do + 就 then + 干 do = say it then do it, no delay
Four chars literally read say-do-then-do. The doubled 干 (do) bracketing 就 (then) signals zero gap between deciding and acting: no sooner said than done. Note 干 here means do or act, not dry.
说 — speech radical 讠(言) + 兑
说 combines the speech radical 讠(言, 'words') with 兑, which acts as the phonetic component. The character originally meant 'to explain' or 'to speak,' and broadened to mean 'say' or 'talk.' The same graph is also read 'yuè' meaning 'pleased,' a sense later written 悦.
干 — pictograph of a forked weapon/shield
干 originally depicted a forked wooden weapon or shield used in ancient warfare, giving the early sense of 'to offend' or 'to oppose.' Over time it took on extended meanings like 'to concern' and 'trunk/stem.' In modern simplified Chinese it also absorbed 乾 (dry) and 幹 (to do; trunk), so one character now covers several unrelated words.
就 — 京 (capital) + 尤 (especially)
Originally a compound suggesting going to a high place (京 depicts a tall building) to settle or accomplish something. Over time the meaning shifted from 'approach a high place' to 'go to,' then broadened to 'accomplish,' and finally to the modern grammatical senses 'then,' 'just,' or 'precisely.'
