How do we ask for a break?

[faya]

Hello, dear teachers!
Could you tell me how to ask my teacher (or even someone else) if I want to leave a classroom for a small break?
My English teacher told me that "come out" is for leaving a building.

Could you tell me how to ask my teacher (or even someone else) if I want to leave a classroom for a small short break?

You've pretty much asked it already! "Please may I leave [the room] for a short break?"

My English teacher told me that "come out" is for leaving a building.

They're right that "come out" would not work in the specific question you want to ask, but they're wrong to suggest that "come out" can be used only when referring to leaving a building.

I'm not sure how "Come out" came up, but I might say it if I might say it if I was outside and I was trying to get somebody to leave the building.

Ron: Bob, come out! Your ride is here.
Bob: OK.

("Come outside" is more likely.)

I think the OP had previously thought they might be able to say "Can I come out of the classroom for a small break" but their English teacher told them "come out" refers only to leaving a building. That's why I agreed it didn't work in this specific context but I disagreed that it refers only to leaving buildings.

You could tell someone to come out of the classroom. (Maybe the building is on fire. ) It doesn't work well as a request though.

I think there's a word missing after "tell". I agree entirely that you can come out of any room but, as you say, it doesn't work if you're the person asking to leave.

Yes, it's my phone's fault.

Then please tell your phone to use the Edit button to add the missing word!
