Will that be an  ER or an RE for your Theatre sir..??
    Isn't the English language great, full of tricky werds to spell and lots of different pro nun c a shons...
  RE is the correct way. it may be different in the States Neil.  Like color  and colour,  colour being the English spelling  ...for example
 - Etymology  is the study of the history of words 
 -Every word in the dictionary can be found in the alphabet 
 -The difference between a good speller and a bad speller is knowing when the spelled the werd wrong.....or something that...I cant remember.
     just part of a perspective .......
