In response to an earlier BBC article on British idiom invading America, I was intrigued by this follow-up of Britishisms reported by American readers. Gobsmacked amused me. I remember that phrase appearing from out of nowhere and sweeping England at the end of the 1980s. Or my bits of it, anyway. I was living in Birmingham at the time.
From my point of view the key learning point is to avoid any of these phrases if, like me, you’re a Brit who often writes in American English. I would like to think I recognize all these examples as Britishisms, but my editor, James, did spot a naughty use of ‘holiday’ in my last novel.
