See, I think of a basement being accessed from a stairwell within the house, while a cellar can only be accessed from an outside source (like those mostly-horizontal outside doors you see on old farmhouses).
If it can be accessed from both, it is still a basement.

That’s how I define it (I have a cellar, as defined here). A REAL cellar will ideally have a dirt floor, but mine has a cement floor.
