# Time: during
## 間
{間|あいだ} means "while" or "during". Used to express something that is done for the whole period of time.

## 間に
V (casual, non-past)
い-Adj
な-Adj + な

+ 間に
A first meaning is similar to {間|あいだ} (while), but with intentionality.

> 電車に{乗|の}った==間に==、本を読みました。
> While I was on the train, I read a book.
A second meaning is a statement of something that happened during a time period, independently of your actions.
Contrary to 間, it doesn't include the whole time period. So 間に means that at a point during the time period, something happened.

> {夜|よる}の==間に==、{隣|となり}の木が{落|お}ちていた。
> During the night, the tree next door fell.
## ながら
Means "while", "simultaneously". The difference with ついでに is that here the main action is the second one.
> [!info] Example
> {歩|ある}き==ながら=={電話|でん|わ}を見ています。
> While walking, I'm looking at my phone.
## ついでに
V (dictionary)
V (た)
N + の

Means "while", "at the same time". The difference with ながら is that here the main action is the first one.

## 中
{中|ちゅう}・{中|じゅう} means different things depending on its pronunciation:
* ちゅう is used when pointing a specific time: "during", "at some point".
* じゅう is used for the entire time or area: "through", "within", "before it ends".

## うちに
