A dotted underline in Microsoft Word typically indicates that the text contains a spelling or grammar error, or it is part of a tracked change. This visual cue helps users identify issues that need review before finalizing a document. You can resolve this by correcting the underlying errors, adjusting proofing settings, or reviewing tracked changes.
Understanding Spelling and Grammar Errors
The most common reason for a dotted red or blue underline is that Word’s built-in editor has flagged the word as incorrect. A wavy red line signifies a spelling mistake, while a wavy blue line indicates a grammatical issue. These underlines are not permanent formatting marks; they are dynamic indicators based on the dictionary and grammar rules loaded into your version of Word. To fix these, simply right-click the underlined text and select the correct suggestion from the context menu. If the word is actually correct, such as a proper noun or technical term, you can choose "Add to Dictionary" to prevent future flags.
It is important to distinguish between these automatic checks and manual formatting. If you have manually applied an underline style, it usually appears as a solid straight line, not a dotted or wavy one. However, some custom styles or themes might alter the appearance of standard underlines. If you suspect your underline is not a proofing mark, check the Font dialog box by pressing
Ctrl+U. If the underline style is set to a dotted pattern, changing it back to "Single" will remove the dots.
Reviewing Tracked Changes
Another frequent cause of dotted underlines is the Track Changes feature. When multiple users edit a document, Word may display deleted text with a dotted underline to indicate what was removed. This allows reviewers to see the history of edits without permanently deleting information until the changes are accepted. If you see dotted lines around text that looks like it was deleted, navigate to the Review tab on the ribbon. Look for the Tracking group and ensure that "All Markup" is selected in the Display for Review dropdown.
If you want to remove these indicators because you have already finalized the edits, you must accept all changes. Click the "Accept" button in the Review tab and select "Accept All Changes and Stop Tracking." This action will permanently incorporate the edits and remove the tracking marks, including any dotted underlines associated with deletions. Alternatively, if you wish to keep the changes but hide the visual clutter, you can switch the view to "No Markup," though this does not delete the change history.
Adjusting Proofing Settings
Sometimes, users inadvertently disable the spell-checker or grammar checker, which can lead to inconsistent underlining behavior. If you notice that new text is no longer being underlined despite containing obvious errors, your settings may have been altered. Go to File, then Options, and select Proofing. Here, you can verify that "Check spelling as you type" and "Mark grammar errors as you type" are both checked. Disabling these options stops Word from generating the dotted underlines automatically.
You might also encounter situations where specific languages are excluded from proofing. If you are writing in a language other than English, ensure that the correct language is selected for the text. Highlight the text, go to the Review tab, and click Language > Set Proofing Language. If the "Do not check spelling or grammar" box is checked, Word will ignore the text entirely, resulting in no underlines at all. Restoring the correct language setting will re-enable the appropriate proofing marks.
Customizing Underline Styles
While rare, some document templates or custom styles define underlines with dotted patterns for aesthetic purposes. This is distinct from the proofing underlines described earlier. To check if a style is causing this, open the Styles pane by pressing
Alt+Ctrl+Shift+S. Right-click the style applied to the underlined text (such as Normal or Heading 1) and select Modify. In the Format section, choose Font and look at the Underline style dropdown. If it is set to a dotted variant, change it to Single. This adjustment applies to all text using that style throughout the document.
For more granular control, you can use the Find and Replace feature to locate all instances of dotted underlines. Press
Ctrl+H to open the dialog, click More, and then click Format > Style. Select the style responsible for the dotted underlines. This method is useful for bulk corrections when multiple paragraphs are affected by a template issue.
If you frequently deal with documents that have excessive proofing marks, you might consider how other formatting features interact with your workflow. For instance, managing inline quotes or equation fitting can sometimes complicate layout views, but these are separate from the core proofing mechanics. Understanding the source of the underline ensures you apply the correct fix without disrupting other elements. See

Frequently Asked Questions
How do I remove all dotted underlines without fixing errors?
You can hide proofing marks by going to File > Options > Advanced and unchecking "Show readability statistics" or disabling "Check spelling as you type." However, this only hides the marks temporarily; the errors remain. To permanently remove them, you must either correct the errors or clear the document's revision history by accepting all tracked changes.
Why is my underline solid instead of dotted?
A solid underline is the default result of pressing
Ctrl+U or selecting the Underline button in the Home tab. Dotted underlines are specifically generated by the spell-checker, grammar checker, or Track Changes feature. If you want a dotted underline for design purposes, you must manually set the underline style to dotted in the Font dialog box, rather than relying on the shortcut key.
Can I customize the color of the dotted underlines?
Word does not allow direct customization of the spell-checker underline colors through standard settings. The red and blue colors are hardcoded to represent spelling and grammar errors respectively. To change the appearance, you would need to modify the theme colors of the document, but this affects all elements, not just the underlines. The most effective way to change the look is to turn off the proofing marks entirely.
What if the dotted underline persists after correcting the word?
If the underline remains after you have fixed the spelling or grammar, try restarting Word. Sometimes the application caches the proofing state and requires a refresh. Additionally, ensure that the text is not protected. If the document is marked as Final or has restricted editing enabled, Word may not update the proofing marks until the protection is removed.
Does this issue occur in other Microsoft Office apps?
Yes, similar proofing underlines appear in Excel and PowerPoint. In Excel, red wavy lines indicate spelling errors in cells, while blue lines may indicate grammar issues in notes. PowerPoint follows the same conventions as Word. The settings to enable or disable these checks are found in the Proofing section of the respective application's Options menu, maintaining consistency across the Office suite.
