However, you could use prefixes like:
* Ortho- (meaning "correct" or "straight") to indicate correct spelling: Orthography is the study of spelling and the rules governing it.
* Mis- to indicate incorrect spelling: Misspelling is a common mistake.
* Pseudo- (meaning "false" or "fake") to indicate a fake or incorrect spelling: Pseudonym is a false name.
It depends on the specific context of how you want to use the prefix!
