Cornfield → The word is formed from "corn" (from Old English *corn*, meaning grain or seed) and "field" (from Old English *feld*, meaning open land or field). A cornfield is an area of open land where grain, specifically corn, is cultivated.
Think of 'grain' ('corn') growing in an 'open land' ('field') — that's what a cornfield is.
