Foniks

When did the pronunciation of certain words change.
When I was growing up.
Coupon was pronounced Q-pon. Now it's pronounced Coopon (coopin if you'reRon White).
Same with mute. It used to be myoot, now it's moot.
Cafe was Caafay, now it's cufay with the emphasis on the first syllable.

And why don't these words rhyme?
What - That
Wash - Bash
Home - Come
Cafe - Safe.

And while we're on the English language.. One word should NOT have twopronunciations.For example:
Live, can be pronounced Liv or Lyve
Read, can be pronounced Reed or Red.

I know you have some more of these language pain in the butts..
What's your favorite?
