Burritos are often contrasted with similar dishes, such as tacos, in which a small hand-sized tortilla is folded beef and cheese burrito half around the ingredients rather than wrapped and sealed, or with enchiladas, which use corn masa tortillas, and are covered in a savory sauce, to be eaten with a fork and knife. The word burrito means “little donkey” in Spanish, the diminutive form of burro, or “donkey”. Before the development of the modern burrito, the Maya civilization of Mexico used corn tortillas as early as 1500 B. The precise origin of the modern burrito is not known.
