An awning is a piece of fabric or other material stretched over a frame that sticks out from a building to provide shade and shelter. You've probably seen awnings over shop windows, restaurant patios, or the front doors of houses. They work like permanent umbrellas attached to buildings, keeping sun and rain off the space below.

Awnings became popular in the 1800s when store owners discovered they could protect their window displays from fading in the sun while also creating comfortable shaded areas where customers could browse. Classic awnings often have bright stripes and a store's name printed on them, turning practical shade into cheerful advertising.

Modern awnings might be made from canvas, metal, or plastic, and some can roll up when you don't need them. On a hot summer day, an awning can make the difference between a pleasant outdoor lunch and an uncomfortably sunny one. They also keep rain from dripping directly onto doorways, so you can fumble for your keys without getting soaked.
