JLPT N5 · Particles
で (de)
～で — place, means and cause
In short · A particle on a noun that shows where an action takes place, what means or tool is used, and sometimes the cause. It answers どこで (where) and 何で (by what).
Pattern
-
場所＋で＋動作place + で + action (図書館で勉強します) -
手段・道具＋でmeans or tool + で (電車で行きます)
Place of an action
It marks the place where an action happens, such as studying, playing or eating. In 図書館で勉強します the library is where the studying happens.
Means and tools
It also shows the way something is done: a vehicle, a tool, a language (電車で, はしで, 日本語で).
Difference from に
The place where something exists is marked by に (机の上に本があります). The place where an action happens is marked by で. Learners often mix these up.
Examples

Common mistakes
- For the place of ある or いる, use に, not で.
- で marks where an action happens. The destination of 行く takes へ or に.
