>>8118113"Corn" originally meant wheat or other cereal grains generally (hence "barleycorn," "broomcorn," "corn dollies" made of straw, etc.). It still commonly means either wheat or barley in England and Wales (though "corn flour" there means cornstarch). In Scots and Irish English it typically means oats. "Corn" exclusively meaning maize ("Indian corn") is an Americanism which eventually spread to Australia and New Zealand.
