About nomad:
is a person with no settled home, who moves from place to place as a way of obtaining food, finding pasture for livestock, or otherwise making a living. The word nomad comes from a Greek word that means one who wanders for pasture. Most nomadic groups follow a fixed annual or seasonal pattern of movements and settlements. Nomadic peoples traditionally travel by animal or canoe or on foot. Today, some nomads travel by motor vehicle. Most nomads live in tents or other portable shelters.
