I had a Plant and Soil Science class with an 80-something-year-old Irishman who would often get onto random tangents, not to mention he was adorable and pronounced ‘potato’ as ‘buh-day-doe’. Anyway,one of his tangents involved the different naming conventions for corn in the US and the UK. He told us that they call it ‘maize’ in the UK and wheat is called ‘corn’. I guess the British have a history of referring to cereal grains as ‘corn’.
