で marks the **context of an active action**, as opposed to に's fixed point. Three dominant uses: place where it happens, means used, material it's made of.

**で (de)**: Action frame, means, material

## Use 1: place where an action unfolds

With an **action verb** (eat, study, sleep, play), the place where the action happens is marked by `で`. The place isn't a destination, it's the **setting** of the action.

> カフェで勉強する。
>
> カフェ de べんきょう する。
>
> Study in a café.

## Use 2: means or instrument

**With what you perform the action**: transport, tool, language.

> 電車で行く。
>
> でんしゃ de いく。
>
> Go by train.

> 箸で食べる。
>
> はし de たべる。
>
> Eat with chopsticks.

> 日本語で話す。
>
> にほんご de はなす。
>
> Speak in Japanese.

## Use 3: material

**What something is made of.**

> 木で作る。
>
> き de つくる。
>
> Make out of wood.

## Memory trick: で vs に

- **Existence → に**: `公園に犬がいる` (こうえん に いぬ が いる): "there's a dog in the park". **Existence** verb (`いる`), so に.
- **Action → で**: `公園で犬と遊ぶ` (こうえん で いぬ と あそぶ): "play with the dog in the park". **Action** verb (`遊ぶ`, あそぶ), so で.

> **Remember** With an **existence** verb (`ある`/`いる`), always **に**. With an **action** verb, always **で** (unless it's a destination, then に).
