Practice JLPTHow to tell them apart
において is a formal written-style compound particle used for the setting of an event, state, or time, while で is the everyday particle for the location where an action happens. Swapping them is unnatural because において sounds stiff in casual speech and で feels too plain in academic or official contexts. The core test is register: 会議において (formal) vs 会議で (casual/general).
- において/おける Use において/おける when you need a formal, written-style expression for the place or time of an event or state.
- で Use で for everyday statements about where an action takes place or a general contextual setting.
