Each of these forms differs from the correct spelling by one small edit: a doubled letter, a dropped silent letter, or a substituted vowel. It also participates in 3 confusable-pair relationships, "príncipe", "princípio", "principado", where similar look or sound leads writers to substitute one word for another in context.
