What does glider mean?
A glider is most commonly a light aircraft that flies by catching air currents in its wings, usually without an engine. In recreational and competitive gliding, pilots use rising air currents known as thermals to gain altitude and remain aloft. The word can also describe a person or object that moves smoothly through the air, such as a bird, a paper model, or a device designed for gliding. In aviation, a glider is valued for the quiet, efficient, and environmentally gentle nature of its flight, although some gliders include an engine for takeoff or emergency use. The related verb glider is less common and means to move in a smooth, gliding manner. Overall, the word evokes controlled, effortless-looking movement, both in the air and across surfaces.

Etymology of glider

Glide descends from Old English glidan and is related to cognate forms in languages such as German gleiten and Dutch glijden; the exact ultimate origin of the shared root is uncertain. The same family includes the noun gliding and the term glideway, a route or slope used for gliding.
