There actually is a difference between a cellar and a basement. A basement is structurally part of the house, is built all or in part as the underground portion of the foundation. They usually have a cement floor and can be made habitable. A cellar is a hole dug under the house, not part of the foundation, and usually with a dirt floor. Mostly used only for storage and tended to be cool for storing roots, bulbs, canned goods, wine, at an even cool temperature. They are rarely built in order to be made habitable, e.g. plumbing, heating, drywall, etc.
