Separated by a common language...

Food is one of those areas where English and American often use different words. We say aubergine, they say eggplant.  We say courgette, they say zucchini and so on. But the one which can really cause confusion and end up getting you something other than what you thought you were going to get is "chips".  In America, these are the deep-fried wafer thin slices of potato which we know as crisps. Our chips, as in fish and chips, are french fries to them.  Why - who knows?  But I would argue that our words have the better derivation.  Both originate from the Latin.  Chip comes from cippus which means a small pillar, which of course is (sort of) the shape of a (British) chip.  Crisp on the other hand comes from crispus which means curled or wrinkled, which accurately describes our crisps.  So I think this is one of the areas where we can claim the linguistic high ground!
