Maize (Zea mays L. ssp. mays; principally known as corn) is a cereal grain that was domesticated in Mesoamerica and then spread throughout the American continents. Maize spread to the rest of the world after European contact with the Americas in the late 15th century and early 16th century. The term maize derives from the Spanish form (maíz) of the Arawak Native American term for the plant. However, it is commonly called corn in the United States, Canada and Australia. Corn is a shortened form of "Indian corn", i.e. the Indian grain. The English word "corn" originally referred to a granular particle, most commonly cereal grains. Hybrid maize is preferred by farmers over conventional varieties for its high grain yield, due to heterosis ("hybrid vigour"). Maize is the largest crop in all of the Americas (270 million metric tons annually in the U.S. alone). source: Wikipedia
