Out or out of which is it? [duplicate]
Solution 1:
In American English (and Ngrams shows British English is moving towards this usage as well, although they're several decades behind AmE) there is a difference between out the house and out the door. What out without an of means is out through.
So you can go out the door, because you were originally in the house, and you go out of the house through the door. But you can't go out the house, because you start in the house.
