I love all those regional variations in UK-English pronunciation
I've always found them fascinating and fun, for some reason. Haha, about the "posh" theme, when we just came to NZ we got friendly with an English family. I was talking the the mum/wife about our house or something, and I mentioned the garage, pronouncing it as "gaRAHGE' , because that's how everyone pronounced in in South Africa (as opposed to "GARrage"). She laughed and said I sounded all posh!
She's from up north (I think from Hull...). At the time I had no idea at the time about thoes North/South variations.... interesting
And it's interesting how some people would say FI-nance and some would say fi-NANCE... or DE-tail and de-TAIL... and the funny thing is that I say "eye-ther" for either but "nee-ther" for neither - so inconsistent
By the way, I suppose I'm closer to "parse" than "pas" (grin)
I always thought English was a very cool language
