Gibbet

n. [Fr. gibet, L. Lat. gibetum, gibetus, It. giubbetto, giubbetta, diminutive of giubba; Prov. It. gibba, an under waistcoat, doublet, mane; so that it probably originally signified a halter, a rope round the neck of malefactors; or it is, perhaps, derived from Lat. gibbus, hunched, humped, crook-backed, convex.]

1Sense 1. A kind of gallows; an upright post with an arm projecting from the top, on which, formerly, notorious malefactors were hanged in chains, and on which their bodies were suffered to remain as spectacles. Swift.

2Sense 2. The projecting beam of a crane, on which the pulley is fixed. Brande.
