Fin

A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilise motion while traveling in water, air, or other fluid media. Fins are also used to increase surface areas for heat transfer purposes, or simply as an ornamentation.

Famous quotes containing the word fin:

“Since the fin has come a little early this siecle and anomie is all the rage, wry, dry tenderness is a suspect commodity.”
—Angela Carter (1940–1992)
