What is it called when a non-verb is used as a verb?
The phenomenon of turning a noun into a verb is very common. Some are more well known, like "shouldering the blame" or "tabling a discussion," while others are newer and less known. I just came across "when it storms." Is there a real name for this or is it just called "verbing?" If not, what was it called before the word "verbing" was coined?
