spell checker

A feature on many computer programs that you can use, it will automatically "spell check" and "grammar check" the text in your document. The spell checker suggests corrections along the way so you won't print letters or send e-mail messages with misspellings and punctuation errors. It is highly recommended to always use the spell checker with important documents. Even to the degree, for example, of copying and pasting your text from an online resume or college application, into a Word document to make corrections, and then copying and pasting it back to the Web site.
