即座に
そくざに · sokuzani · JLPT N1 · adverb
immediately
⚡ 即 = at once + 座 = seat: act on the spot, without leaving your seat
Sounds like 'so quick, sit': when someone acts right away, they respond at once, right where they stand or sit.
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.
座 — 广 (shelter) + 坐 (to sit)
Originally written as 坐, meaning 'to sit' (two people 人人 sitting on the ground 土). The shelter radical 广 was added to specify the place where one sits — a seat, throne, or platform. 坐 remained the verb 'to sit,' while 座 became the noun 'seat.'
