Definitions for "Hackamore"
A halter consisting of a long leather or rope strap and headstall, -- used for leading or tieing a pack animal.
The word is thought to come from the Spanish word jáquima, meaning "head stall." It resembles a bridle and was often used as a halter for riding (with a pair of reins attached) and to handle and break broncos. Unlike the bridle, a hackamore does not use a bit in the horse's mouth for control; instead, pressure is applied to a rawhide noseband to control the horse.
A bitless bridle that controls a horse by pressure on its nose and jaw ( from Spanish jáquima bridle [1850])
