Did you know that in British English pour and paw sound identical?
I can't quite figure out how to get my mouth around that.
For me, they rhyme with door and saw, it just doesn't work somehow.
Languages are the most peculiar things....
try this out, words with ough in them:
Say each of them aloud and listen to all the different sounds those 'ough's make.
a roughty toughty brutal sort of language.
