Turn Off Spelling and Grammar Checking in Word Options

Disable Word's native proofing features through the application settings so Grammarly becomes your sole proofreading tool.

By disabling the built-in proofing tools, you eliminate the overlapping red and blue underlines from Microsoft Editor, allowing Grammarly's suggestions to display cleanly.

Open Microsoft Word. Click on the 'File' tab in the top-left corner of the ribbon, then select 'Options' at the very bottom of the left-hand menu.

2
Navigate to Proofing Settings

In the Word Options dialog box that appears, select 'Proofing' from the categories listed on the left side.

3
Disable Automatic Checking

Scroll down to the section labeled 'When correcting spelling and grammar in Word'. Uncheck the boxes for 'Check spelling as you type' and 'Mark grammar errors as you type'.

4
Apply Changes

Click 'OK' at the bottom of the dialog box to save your preferences. Word will no longer display its default spelling and grammar suggestions.

Turn Off Spelling and Grammar Checking in Word Options
Settings Applied Globally: These changes will apply to all future documents opened in Microsoft Word. Grammarly will now handle all spelling and grammar suggestions exclusively.

Frequently Asked Questions

Why do I see double underlines when using Grammarly in Word?

Double underlines occur because both Microsoft Word's built-in Editor and the Grammarly add-in are actively scanning your text at the same time. Disabling Word's native 'Check spelling as you type' setting resolves this visual overlap.

Will turning off Word Editor delete my custom dictionary?

No, disabling the live spelling and grammar checks only hides the real-time suggestions. Your custom Microsoft Word dictionary remains saved and can be reactivated anytime by re-checking the proofing boxes.

Does Grammarly work automatically after disabling Word Editor?

Yes. As long as the Grammarly desktop application or Word add-in is installed and you are logged into your Grammarly account, it will automatically take over the proofing duties without interference.

How do I turn Microsoft Word Editor back on?

To restore Word's default proofing, simply navigate back to File > Options > Proofing, and re-check the boxes for 'Check spelling as you type' and 'Mark grammar errors as you type', then click OK.
