Definition: A "taxiway" is a special road at an airport where airplanes move slowly to get from one place to another, usually to or from the runway, where they take off and land.
In aviation or airport planning discussions, you might hear phrases like: - "The taxiway must be clear for the safe movement of aircraft." - "The airport has several taxiways that connect different runways."
In summary, a "taxiway" is a vital part of an airport where planes move on the ground.
