As I’ve said before everything I’ve learned about the King’s English I’ve learned from watching the BBC here in America. Something I’ve noticed is that Brits tends to, I don’t know if there’s a word for it, but they tend to ‘reconfirm’ everything. In other words they say things like:
She didn’t do that, did she?
or
That’s not what happened, is it?
or
I didn’t do that, did I?
IOW they add a confirmation at the end of any declaration. We certainly do that in the US, but it seems like Brits do it much more consistently.
Is this a regional thing? Or a British thing? Or am I just crazy, aren’t I?
The thread right above this one is talking about exactly this, in another form. Americans say, “right?”, “you know what I mean?”, “yeah?” or apparently some (mainly youth) just inflect their voice up as if seeking confirmation on every single sentence.
