How would "No English Zone" or "No English Allowed" be translated? My roommate and I are trying to force ourselves to practice more speaking and want to essentially but a ban on the use of English a little at a time. We want to make a simple sign to that we can hang in a random room for a week at a time. That room, whenever we are in it, would be where we cannot speak English before completely banning it from the house. But every time I try to do a literal translation, it seems odd. How would this be translated to this context more naturally in Korean?
