The cereal ambiguity of ‘corn’

‘Wha, wha?’ said my husband in a slack-jawed way, throwing over a copy of the Guardian, as though it was my fault. ‘“Today,” it said, “just three crops – rice, wheat and corn – provide nearly half of the world’s calories.”’ I saw the problem. It was obvious, from a process of elimination, that by corn it meant ‘maize’.

Elsewhere ambiguities abound. Since the Ukraine war began, discussion of wheat and maize has increased no end, but it is often impossible to tell whether wheat or maize is meant by corn.

I thought we had agreed to differ with America on this. ‘As a general term the word corn includes all the cereals, wheat, rye, barley, oats, maize, rice, etc,’ the Oxford English Dictionary remarks chattily in an entry not fully updated since 1893. ‘Locally, the word, when not otherwise qualified, is often understood to denote that kind of cereal which is the leading crop of the district; hence in the greater part of England corn = wheat, in North Britain and Ireland = oats; in the United States the word, as short for Indian corn, is restricted to maize.’

They began early with the ‘maize’ meaning. In 1608, Captain John Smith, fresh from killing Turks and escaping their slavery, found himself in charge of the colony of Virginia. ‘It pleased God (in our extremity),’ he recorded, ‘to move the Indians to bring us Corne, ere it was halfe ripe, to refresh us, when we rather expected they would destroy us.’

Corn moved happily from ‘wheat’ to ‘maize’ because at bottom it meant ‘grain’. Indeed it is grain that Americans today call the variety of cereals. In deep history, the words corn and grain come from the same origin.
