An improved method for correcting spelling errors in text wherein candidate expressions for replacing a misspelled word are assigned probability functions. The misspelled word can be replaced automatically with the candidate expression having the highest probability function or candidate expressions can be displayed to a user in rank order of their probability functions for the user to make a choice. The probability function for a candidate expression is based on (1) the probability of occurrence of the candidate expression appearing in text and/or (2) the probability of occurrence of the particular typographical modification needed to convert the candidate expression into the misspelled word.
