Corn, Maize: the conventions of naming - The term "maize" comes from the Spanish form of Maiz, a Taino word for the original plant. This was the term used in the UK and Ireland, where he is now usually called "sweet corn", the most common type of plant known to the people there. Sweet corn is harvested earlier and eaten as a vegetable instead of a grain.
Outside the British Isles, another common term for corn is 'maize'. It was originally the term for other cereals. In North America, its meaning has been restricted since the 19th century for corn, and was reduced to "corn". Corn term now refers specifically to the colorful "corn" (corn Flint) cultivars.
