Why is it that most English speaking people EASILY pronounce the letters "as" in Douglas, Christmas, Nicholas, Lucas, Banderas, Thomas, and all other such names or words with the same ending correctly but seem unable to pronounce the "as" or" "az" in Dias or the "az" in Diaz correctly? Do the same to the above names and the reason for correct pronunciation should be obvious! It comes across as ridicule.
Example:
The lady on Comcast who is advertising Cameron Diaz' latest film has a
Field day with the name's possessive form.
