Quick Question: What word can you never spell correctly?

There are some words that I can never spell right – no matter how many times I look them up or learn the “rules”. I’ve tried visualising them and learning little rhymes. I’ve even checked out some memory aids. But nothing. Some words just stick when I go to write them in a sentence.  So here goes. The words I always get wrong (except for now because I just  looked them up)…

disappear

separate

definitely
