A supermarket is a big store that sells a wide variety of food and other household items.
When we talk about supermarkets, we usually mean the places where people go to buy groceries, but they often sell a lot more than just food. You can find everything from fresh produce to cleaning supplies in one big building. Many cities have several supermarkets, so you might have a choice between different stores to shop at. Some people prefer to go to smaller specialty stores for certain items, like bakeries or fish markets, but supermarkets are great for getting a lot of things all in one place.
A large self-service store that sells groceries and, usually, medications, household goods and/or clothing.
Example: I went to the supermarket to buy some food.
