I almost put in "週ますはコスプレをしまつ".
Only accepting half the word in kanji is stupid. You should accept 週末.
I've gotten counted wrong for doing that on here in the past. Duo seriously lacks consistency...
Doesn't matter and has zero effect on the sentence. The particle after "weekend" is usually dropped anyway.
That's what I thought as well. I was looking for に.
And how do you "cosplay"?
Cosplaying means to dress up and act like a character. The employees at Disney World, for example, cosplay for work.
Should the a wo(を,) after コスプレイ?
