There's a few, but tonight I for some reason could not spell 'disengage' - I wanted to add an extra 'n' to be 'disengange'. Can't explain my reasoning behind that either, it just kept coming out that way when I typed fast.
mississipi? or misissippi? or mississippi? or misisippi? lol
I always browse out the right spelling before writting, but the next second I forgot already hahaha
