Questions & Answers about aratta uwagi o hangaa ni kaketa mama heya ni oite oita.

How should this sentence be broken into chunks?

A helpful way to read it is:

• 洗った上着を = the washed jacket / the jacket that was washed
• ハンガーにかけたまま = while still hanging on a hanger / in the state of having been hung on a hanger
• 部屋に = in the room
• 置いておいた = left there / put there and left there intentionally

So the grammar flow is:

[washed jacket] + [still on a hanger] + [in the room] + [left it there]

What does 洗った上着 mean exactly?

洗った modifies 上着.

In Japanese, a verb in plain form can directly describe a noun:

• 洗った上着 = the jacket that was washed
• more naturally in English: the washed jacket

This is a very common pattern in Japanese. English often uses that/which or a participle like washed, but Japanese just places the verb before the noun.

Why is there no word like that or which between 洗った and 上着?

Because Japanese relative clauses do not use a relative pronoun.

English:

• the jacket that I washed

Japanese:

• 私が洗った上着
• or simply 洗った上着 if the subject is obvious or not important

So Japanese does not need a separate word for that/which in this kind of structure.

Why is attached to , even though comes after it?
