[Maxful]

Hi, I would like to know how to use this verb "しまいます" as "put things in their proper place"? I find it confusing because "まとめる" and "片付ける" can also be used when referring to tidy things up and put things together.

I do know that "しまいます" can be use like the following sentences, too.


宿題はもうやってしまった。
I have finished my homework.

財布をなくしてしまった。
I lost my wallet.
