Microsoft Word offers users the ability to check for punctuation errors when creating documents. The program can detect errors when the user selects the appropriate grammar settings to personalize the program to his specific preferences.
To automatically check for common punctuation errors, click the Options tab in Word, and then click on Proofing. Under Settings, display the Grammar settings box, and then modify the settings according to the errors Microsoft Word should check. For example, to require a comma before the last item in a list, check the box to indicate Always or Never, or leave the box unchecked to make the program skip detecting this common punctuation error. Other errors Word checks for if customized to do so include punctuation required with quotes and number of spaces required between sentences.
