hinge (hĭnj)
n.
A jointed or flexible device that allows the turning or pivoting of a part, such as a door or lid, on a stationary frame.
(Heb. tsir), that on which a door revolves. "Doors in the East turn rather on pivots than on what we term hinges. In Syria, and especially in the Hauran, there are many ancient doors, consisting of stone slabs with pivots carved out of the same piece inserted in sockets above and below, and fixed during the building of the house" (Prov. 26:14).
hinge on
Also, hinge upon. Depend or be contingent on, as in This plan hinges on her approval. This expression employs the verb hinge in the sense of "to hang," as a door would hang on a hinge, a usage dating from the early 1700s.
