I need to improve my spelling. I need a list of words that are "difficult" but useful. I struggle with ence/ance and double letters.
I have collected a list of spellings that I know I have trouble with but need more. So far I am learning:
necessary/success
discrete/discreet (thanks pedants)
embarrass/embarrassment
sentence
separate
definite (pedants again)
religious
Until someone pointed out definite and discrete/discreet I did not even know I was getting them wrong, 
so there are bound to be a lot more that I have no idea I am getting wrong.
Help please!
