Cream is the part of milk that's especially rich, creamy, and fatty. Many people like to add cream to their coffee.
Heavy cream can be whipped until it's thick, and light cream might be added to a soup or sauce to add richness. Another kind of cream is a thick lotion, like a skin cream or a night cream. When you cream ingredients together, you mix them until they're fluffy. Calling someone "the cream of the crop," means they're the very best at what they do, and when you cream someone in a game of tennis, you win easily.
