I often see questions asking "Is ____ idiomatic?" I learned a while ago when answering a question like this for the first time that there are two possible meanings - "Is _____ an idiom?" or "Does ____ sound natural to native English speakers?" Most of the time it is the latter, but the questions would be so much clearer from the start without this word. Is there anything that can be done to discourage use of this word when the intended meaning is not otherwise specified? Or what is the best way to handle questions like this when it is unclear?
Also, before anyone downvotes thinking that "idiomatic" is never used to describe idioms, it is in the US. I have had that debate before so I'd rather avoid it here.
