This isn't a spelling but a typo, but I keep mistyping "immortal" as "immportal" more than half the time.
As for actual misspellings, I can't think of any, but as a kid, I did not know how "restaurant" was properly spelled for a long time, because I kept spelling it as "restraunt" and every spellchecker ever only has the suggestion "restraint".
Fun fact: I actually thought "baloney" was actually "bologna", another misspelling I had for a long time because it is a correct spelling of the wrong word and thus the spellchecker could not correct it.

Banned entirely for telling FE that he was being rude and not contributing to the discussion.
