"I've said it before and I'll say it again. The correct form of any language is that which is spoken in the Capital City"
.,,.
Sorry, Bert; nice try!: but an untenable statement. The capital's own specific accent [Cockney in our case] is as 'regional' as any other. "The correct form of any language" is that accepted as such by the educated; & here in UK that is so-called RP ['Received Pronunciation'].

You might not like it, but such is the fact. Sorry. And please note that this is no sort of denigration of any dialectal variants, but simply a semantic comment on the only acceptable connotation of the word "correct" in the particular context of this dialogue.

I have no more to add to this thread, as we have been thru it all before, at least twice, within the past year or three; in such threads as my "Why 'mid-Atlantic'?", which drifted to make all the points now being made here.

Er ~~ Innit!
