-- Most words that have a C before an IE (because that rhyme about I before E, except after C is only true sometimes.) Worse yet, this is what my misspells look like:
conceieve, receieve, etc.
-- Melchizedek! (Well, I couldn't spell his name right for three months anyway. lol)
-- There, they're and their. I know what each means and how to spell them, but I tend to mentally choose the wrong one more often than I choose the right one.
-- embarrass or harrass, but mostly if I spell one right and then need to spell the other soon after. (How come one has two R's and two S's, but the other one doesn't?)
-- Moyamensing and Schuylkill (both spelled right there.) Not a big deal, unless you live a few houses away from Moyamensing Street, and the Schuylkill River divides the city you live in and is also an expressway to travel north-south through that city.
Worse yet, I have aphasia, so at any moment I can use a word that sounds like another word, but has nothing to do with the other word. If you watch carefully, you can sometimes see me write Why, when I meant While, Divide, when I meant Dive, or Operations, when I meant Options. lol
