Corn vs. Maize
“Corn” and “maize” overlap in the crop sense, especially across US and UK usage, but they are not interchangeable in every sense. US “corn” commonly means maize; UK “corn” can be a broader cereal-grain term, so regional and sense context matters.
In US English, “corn” commonly names maize. In UK English, “maize” is the specific crop term while “corn” can refer more broadly to cereal grain, so match the word to region and sense.
