Haggard has its origins in falconry, the ancient sport of hunting with a trained bird of prey. The birds used in falconry were not bred in captivity until very recently; traditionally, falconers trained wild birds that were either taken from the nest when quite young or trapped as adults. A bird trapped as an adult is termed a haggard, from the synonymous Middle French word hagard. Such a bird being notoriously wild and difficult to train, haggard was easily extended to apply to a “wild” and intractable person. Eventually, the word came to express the way the human face looks when a person is exhausted, anxious, or terrified. Today, the most common meaning of haggard is “gaunt” or “worn.”
