difference between grocery store and supermarket

• Although in common usage the words are used as though they are the same, the distinction between them is size. Grocery store is a general term. While a supermarket is a grocery store, a grocery store is not always a supermarket. A supermarket is very large and usually has a variety of departments that wouldn't be found in a smaller grocery store; pharmacy, post office, fast food, walk-in clinic, etc.

• A grocery store is usually smaller than a supermarket

• Grocery stores are big or little. Supermarkets are only large.
