Misspelling refers to spelling a word incorrectly. Misspelling is distinguished from other errors in writing, such as grammatical errors, incorrect capitalization or misuse of punctuation. A misspelled word can be a series of letters that represents no correctly-spelt word at all (such as "liek" for "like") or a correct spelling of another word (such as writing "here" when one means "hear", or "now" when one means "know"). Misspellings of the latter type can easily make their way into printed material, because they cannot be caught by computerized spell-checkers.
