Edit AutoCorrect Settings in Microsoft Word

Changing AutoCorrect settings in Microsoft Word lets you control which typing errors Word fixes automatically, add shortcuts for text you use often, and remove corrections that cause problems. The steps differ slightly between Windows, Mac, and Word for the web; you may need the desktop app to access the full set of options.

What You’ll Need

• Microsoft Word for Windows or Mac for the full AutoCorrect settings. Some options may vary by app version and language.
• A document is optional; you can change these preferences without opening a particular file.
• If you use a work or school device, your organization may manage some Office settings.

Step-by-Step

1. Open Word’s options on Windows. Open Word, select File, then Options. In the Word Options window, choose Proofing. Select AutoCorrect Options to open the settings dialog.
2. Open AutoCorrect settings on Mac. In Word, select Word in the menu bar, then choose Preferences or Settings, depending on your version. Open AutoCorrect. If you cannot find it, use Word’s Help or command search to locate AutoCorrect; menu labels can change between releases.
3. Review automatic replacements. In the AutoCorrect tab or window, look for the option to replace text as you type. The replacement list pairs a typed entry with the text Word inserts. To stop a specific replacement, select its entry and choose Delete. This removes that correction from the list; it does not disable every AutoCorrect feature.
4. Add a custom correction or shortcut. In the replacement fields, enter the text you want Word to recognize and the replacement text. For example, you might set a short, distinctive abbreviation to expand into a longer phrase. Select Add, then confirm with OK or close the settings window as prompted. Test the entry in a blank document by typing the shortcut followed by a space or punctuation mark.
5. Turn individual behaviors on or off. Review the checkboxes on the AutoCorrect tab. Depending on your Word version, they may include correcting two initial capitals, capitalizing the first letter of sentences, or replacing straight quotation marks with smart quotation marks. Clear only the checkbox for the behavior you want to stop. These settings are separate from the replacement list.
6. Adjust capitalization and formatting rules if needed. Other tabs in the dialog may control automatic capitalization, capitalization exceptions, or formatting as you type. Read each option before changing it: these features can affect lists, headings, ordinals, and other text without using a custom replacement. Make one change at a time so you can identify its effect.
7. Save and verify the change. Select OK or close the preferences window using its confirmation control. Type a test phrase in a new or disposable document. If you changed a capitalization rule, test a sentence; if you changed an entry, type it with the punctuation or space that normally triggers replacement.

Common Mistakes

• Confusing AutoCorrect with spellcheck. AutoCorrect changes text as you type. Spellcheck flags possible errors and may offer suggestions without changing them automatically. A red or blue underline is not necessarily an AutoCorrect entry.
• Disabling too much. Turning off the general replacement option can stop all text-pair corrections, including useful built-in fixes. If only one correction is troublesome, delete or edit that entry instead.
• Testing without a trigger. A replacement may happen only after a space or punctuation mark. Typing the entry and immediately stopping may make it seem as if the setting did not work.
• Using a common shortcut. A short word or letter sequence can be replaced unexpectedly inside regular writing. Choose a distinctive shortcut and test it in ordinary sentences before relying on it.
• Expecting settings to match across every app. Word for the web, desktop Word, mobile apps, and other devices may expose different controls or store preferences differently. Confirm the setting in the version where you type.

Tips

• Keep a note of custom entries that you depend on, especially if you use several devices or may need to rebuild your preferences.
• Use AutoCorrect for predictable, repeated changes such as expanding a unique abbreviation. For longer reusable passages, a document template or another text-insertion feature may be easier to maintain.
• When testing, use a blank document or undo immediately. This avoids changing important content while you check a new rule.
• If you work in multiple languages, check the proofing language of the text. Word’s correction behavior and available entries can depend on the language assigned to a passage.
• Change one option at a time. If Word starts capitalizing or formatting text unexpectedly, you can return to the same dialog and identify which setting caused it.

Troubleshooting

The AutoCorrect option is missing. Check that you are using the desktop app rather than Word for the web, then look under Word Options > Proofing on Windows or Word > Preferences/Settings on Mac. Search Word’s Help or command search for “AutoCorrect” if the menu layout differs. Some managed installations restrict settings.

A custom entry does not replace text. Confirm that the replacement feature is enabled and that the entry appears in the list with the correct spelling. Type the shortcut exactly, then add a space or punctuation mark. Also check that the document language and keyboard input are as expected.

Word keeps making an unwanted correction. Open the replacement list and look for the exact text Word changes. Delete that entry if present. If the change is capitalization or formatting, review the related checkboxes and exception lists instead. Close and reopen the dialog to verify the change was retained.

The same setting behaves differently elsewhere. Check whether the other device is using Word for the web, a mobile app, or another desktop installation. Sign-in and synchronization behavior can vary, so set and test the option in each version you use rather than assuming every app shares the same controls.

Changes will not stick. Confirm the dialog with OK or its save/close control, then test again. If settings revert, restart Word and check whether an organization policy or account configuration is restoring them. Contact your workplace or school support team if the device is managed.

Frequently Asked Questions

Can I turn off AutoCorrect completely?
In desktop Word, clear the main option to replace text as you type in AutoCorrect settings. This may stop replacement-list fixes, while separate capitalization or formatting options can remain active.

How do I stop Word changing one specific word?
Open the AutoCorrect replacement list, find the unwanted pair, select it, and choose Delete. If it is not listed, check capitalization and formatting settings.

Can I make Word automatically expand an abbreviation?
Yes. Add the abbreviation and its full replacement to the AutoCorrect list, then test it with a space or punctuation mark. Choose a shortcut that will not occur in normal text.

Do AutoCorrect changes affect existing documents?
They generally affect text as you type or edit; they do not automatically scan and rewrite every existing document. Existing text changes only if you edit it in a way that triggers a rule.

Are AutoCorrect settings the same in Word for the web?
Not necessarily. The web app may have fewer controls than desktop Word. If a setting is unavailable online, use the Windows or Mac desktop app and check the result in your usual workflow.

Why does Word still underline a word after I change AutoCorrect?
An underline is usually a proofing suggestion, not an automatic replacement. Check the document’s proofing language and spelling settings, or review the suggestion separately from AutoCorrect.
