backyard

A backyard is the open space at the back of someone's house where they often spend time and grow plants or flowers.

The word "backyard" usually refers to a specific area outside of your home that's just for you. You might think of it as a smaller version of the front yard, but instead, it's behind the house. It could be small enough for a few pieces of furniture and some greenery or large enough for a garden, pool, or even a tiny patio where you can sit with friends and family. The idea is that this space belongs to your home and is meant for relaxation or entertainment.
