zebra. The African cross between a horse and ass could be named for the wind god Zephyrus, because of the animal’s swiftness, but zebra most likely comes from the Abyssinian word zebra, for “the striped beast.” Referees in several sports, including football and basketball, wear black-and-white striped shirts while officiating games. Because of these colors, fans have been calling them zebras since about 1975. In medical jar- gon zebra means an unlikely or obscure diagnosis, a shortening of the old advice to doctors: “If you hear horses’ hoofbeats go- ing by, don’t look for zebras.” |
