Also there are pronounciation differences, for example, Herbs. That's not a silent H for us, but I think it is in America. I also noticed that some car manufacturer names were pronounced different when I went on holiday to America. Hyundai was pronounced Hun-day whereas here it is Hi-yun-die, and Nissan was pronounced Nee-saan whereas here it is Nis-ann. There could be more but they are all the ones I remember off the top of my head.
