Flügel

Flügel is a German noun meaning wing. It can refer to the wing of a bird or insect, a wing of a building, or by extension to a subunit or offshoot within an organization, such as a political party’s left or right wing.

In architecture, Flügel denotes a lateral section of a structure that is often mirrored across a central axis. Buildings may be described as having Hauptflügel (main wing) and Nebenflügel (side wing), with wings arranged to form courtyards, divisions of function, or ceremonial spaces.

In music, Flügel is the German term for a grand piano. A concert grand is specifically called a Konzertflügel, distinguishing it from other piano types such as upright pianos.

Flügel also functions as a surname in German-speaking regions, and individuals bearing the name appear in various historical and contemporary contexts.

Etymology and usage derive from the core sense of wing, reflecting how the word describes projections, extensions, and divisions in both natural and man-made forms.
