当即
dāng jí · HSK 7
on the spot
⚡ dang! ji-ust like that — it happened at once
当 (dang) sounds like an exclamation of surprise, 即 (ji) sounds like 'just.' When something happens so fast you can only say 'dang, just like that!' — thats at once, on the spot.
当 — small ⺌ + crown 冖 + hand 彐 (simplified from 當: 尚 + 田)
Originally written 當, combining 田 'field' with 尚 as a phonetic. The early sense was 'to match' or 'face' a field of equal value, extended to 'correspond to', 'ought to', and 'serve as'. The simplified form 当 streamlines the upper 尚 component.
即 — 皀 (food vessel) + 卩 (kneeling person)
Originally a pictograph showing a person kneeling beside a food vessel, about to eat. The original sense was 'to approach (the meal)' or 'to draw near.' From this came extended meanings like 'immediately,' 'at once,' and 'namely,' since approaching something happens right away.
