Apart from apart, one of the most commonly misspelled words is misspelled. Also is also often misspelled, though not as often as often.
Mispronounced is rarely mispronounced, but is usually spelled incorrectly. Obviously, spelling mispronounced as “incorrectly” is the incorrect way to spell mispronounced–but IS the correct way of spelling incorrectly, both literally and figuratively.
“Literally” is spelled literally–literally. “Figuratively,” oddly, is spelled figuratively, literally. But that’s ok.
And, for the record, the way OK is spelled? Is usually ok.
