corn

The Old English corn comes from Proto-Germanic *kurną, meaning 'grain' or 'seed' — any grain, any seed. In medieval England, corn meant wheat. In Scotland, it meant oats. In Germany, Korn means rye. The word was a generic: whatever the local staple grain was, that was corn. The King James Bible refers to 'corn' in ancient Egypt and Palestine — it does not mean maize, which would not reach the Old World for another three thousand years.

When English colonists arrived in the Americas, they encountered maize — a crop domesticated in Mexico around 7000 BCE by indigenous peoples who bred a wild grass called teosinte into the large-eared grain we know today. The colonists called it 'Indian corn,' meaning 'the grain of the Indians.' Over time, the modifier 'Indian' was dropped, and 'corn' in American English came to mean exclusively maize. The generic word became specific.

This split causes confusion to this day. When an American reads about 'corn' in the Bible, they picture yellow cobs. When a British writer mentions 'corn laws,' they mean grain tariffs on wheat. The Corn Laws of 1815–1846 were about wheat prices, not maize. The word is the same in both dialects, but it points at different plants across the Atlantic.

Maize is now the most produced grain on earth — over a billion metric tons annually, surpassing wheat and rice. The United States alone produces about 350 million tons per year, most of it for animal feed, ethanol, and corn syrup. The generic Old English word for 'seed' became the American name for a specific Mexican crop that now dominates global agriculture. The word meant everything. Then it meant one thing.
