Oh gosh so many... Being dyslexic just kills me with a ton of words, I mostly changed what words I use when typing to avoid those haha.
For some examples, stuff with c's and s's mess me up. Concession, incessant (literally had to look that up because even autocorrect couldn't tell what I was getting at), stuff like that, Had to learn to spell "chiaroscuro" consistently for a story I was writing and that was a hassle.
