I'm not actually a language learner myself, I'm actually an English language teacher, but I want to put together some information for my students regarding some of the difficulties they often face.
I've been looking into the usage of "ever" and have noticed something:
It seems "ever" can be used quite naturally in close-ended questions (Have you ever...; do you ever...; did you ever...) and yet not in open-ended ones (What cities have you ever lived in? What kind of food have you ever eaten?).
Admittedly I have been living abroad for over a decade so maybe my radar has gone off, but would you agree that it doesn't sound as natural to use "ever" in open-ended questions? If so, is there any way to account for this?
Any and all replies are appreciated, thank you!
