As you type and when you open an existing document, Word examines content and will mark text with the following indicators

  • Red wavy underline: potential spelling error.

  • Green wavy underline: potential grammar error.

  • Blue wavy underline (Word 2002 and Word 2003): formatting inconsistency.

  • Red dotted underline (Word 2002 and Word 2003): smart tag.

Important notes about these indicators:

  • To find out why a word or phrase is marked, right-click it. The shortcut menu will provide options for you to correct a potential error or leverage a smart tag feature.

  • Please, if a word is marked as misspelled and you know it is correctly spelled, add it to your dictionary! Right-click the word and choose Add.

  • The markings do not print. So you can, if you choose, ignore them.

  • The markings can interfere with your work. For example, if you are trying to format text, but that text is marked with a wavy underline as a potential error, the right-click menu will display commands related to correcting the potential error. You will not be able to access the normal shortcut menu until after you make a selection regarding the potential error. So maybe you can't ignore them all the time.

  • The markings will reappear. If you choose to Ignore a marked error, the next time you open the document, Word will again scan the document, identify the potential error, and mark it accordingly.

  • The markings will reappear (again). If you add a word to your custom dictionary, the red wavy underline will disappear. When another user opens the document, their dictionary may not contain that word and so the word will be marked again.
