Quick Summary

A hinge is a mechanical device that allows an object, such as a door or lid, to swing or pivot. It typically consists of two parts, called leaves, connected by a pin or a flexible joint. This connection enables the object to open and close smoothly.1

Hinges can also be described metaphorically as a determining factor or a turning point in a situation. The verb "to hinge" means to swing on a hinge or to be dependent on a specific consideration. For example, a case might hinge on crucial evidence. There are also specialized types, like an "H hinge," named for the shape its leaves form when open.123
