Maize is another word for corn, the tall-growing grain that produces yellow kernels on long ears. A small farmer might grow several different types of maize.
Maize is more commonly used in Britain than in the United States to talk about corn, but most Americans recognize the word. Sweet maize is the variety that tastes the most delicious — other kinds of maize are grown as grain to feed animals. The word maize comes from the Spanish maíz, or corn, and both the word and the grain itself moved north from Central and South America into North America, where it became the continent's largest grain crop.
