Etymology

Origin of hinge

1250–1300; Middle English henge; cognate with Low German heng ( e ), Middle Dutch henge hinge; akin to hang

Explanation

A hinge is a type of joint that attaches two things together while allowing for limited movement. A door hinge fastens the door to the wall and lets the door swing open. A hinge is a joint that holds two pieces of something together while allowing one piece to move in a swinging motion. When used as a verb, hinge can mean "to attach a hinge." Hinge can also be used to indicate that one key event depends on another, as in “The athlete’s future with the team will hinge on his performance at tonight’s game” or “The success of this product hinges on how many units are sold this month.”
