Americans have "corn maze" which is a big FAIL compared to the beauty of "maize maze". To Americans corn=maize, to us corn=some general unidentified cereal, or wheat. The other stuff is, of course, sweetcorn.
A word that is particularly confusing is "momentarily", which to us means "for a short while" or "briefly" but to them means "in a short while", where we'd say "shortly" or "presently".
