I was lying in my bed thinking "I really want some chips". Then I got thinking about how if I said that to American, they'd assume I meant these:
Because they're known as chips in America, if I'm not mistaken?
& what I know as chips, are fries in America, I believe, though perhaps not quite the fries they're used to.
I can't think of any more examples of words like this though, and I'm quite curious to see how many different words there are that are used by Brits and taken to mean something else by Americans & vice-versa.
