A cellar seems mainly for storage, whereas a basement is multi-purpose: storage, washer/dryer, tools, desk, etc. Basements also sometimes get renovated int an additional bedroom or even an entertainment room; I've never heard of anyone doing that to a cellar. :-)

Hi Mody. A cellar is a room under the ground floor, usually for storage, whereas basement is a part of building that is completely or partially below the ground level, it could be an apartment, a kitchen, or rooms. A lot of people also store things in their basement or have their washing machine and dryer down there.

A basement is for random junk, a cellar is for wine.
