Well, there's certainly nothing wrong with that, so it must be
something else's understanding that is wrong... <wink>

Are you sure you aren't forgetting case-sensitivity?  I still
don't really understand your code, but I get a sense from the
above that you are expecting "AWORD" to equal "aword", which 
is not the case (no pun intended).

If this is true, try using word[0].upper() == firstword[i].upper().
