What's the difference between brand new and new? Asking for a friend.
It's usually just a matter or emphasis -- "brand new" just emphasizes that something is new. But also sometimes "new" means "new to you". For example, you got rid of your car and then bought a used one. You could call this car "new" because it is new to you, though it is used. But if you wanted to say you bought a car that is absolutely new and has not been driven, then you could say "brand new".
There ya go just copied and pasted that from. Google for you
