An airfield is an area of land or water used for takeoff and landing by aircraft. It's like a big park for planes.
You often hear about airfields when talking about travel or transportation. For example, if you're going on a trip to another country, you might arrive at a busy airport with lots of flights coming and going from different airfields around the world. But not all airfields are airports – some are smaller places where pilots can stop for fuel or maintenance on their way somewhere else. In that case, it's like a little pit stop for planes!
An open field designated for the taking off and landing of aircraft, but which, unlike an airport, does not necessarily have terminals or paved runways.
