“I haven’t known”
A friend and I were having a discussion. The question asked was: what is the meaning of “I haven’t known?” If it’s even correct to say such a thing, which I suspect it is. I have a vague notion in older English usage of “I have known various women” and the negative of that, etc.
My friend was trying to ask me if it’s possible with that statement to indicate that something was not known at a point in the past, but is known in the present.
The example: Person A: Did you hear that Henry’s car is broken? Person B: I haven’t known.
Does such a thing make sense? Why or why not?
Any help in the explanation of this would be appreciated.
