Researchers from the universities of Portsmouth and Cambridge found that differing pronunciations of words such as strut and farm will soon merge into the south-eastern version.

1. Out or nowt?
Well, do you want 'out or nowt' from bar? In other words, do you want anthing?

Buzz is obviously the right way to pronounce bus.
Barm or tay cake for this, please. It's not a bread roll, we're not down south, you know.
