I've mentioned on here before how much I love that word 'innit?'. (Used at the end of seemingly irrelevant statements, for example: "He looks cool in them trousers, innit?" I suppose it could be 'translated' as 'Is that not so?'.
Well, I've got to know a black chap who lives down my road with his white wife. He's of Caribbean origin but lived most of his life in West London, where I spent my childhood. (We discovered we'd been born in the same hospital in Hillingdon!) He uses 'innit' without let or hindrance, and has me in stitches! I think it's my favourite word, innit?
