Solution 1Recommended

Disable or Update the Grammarly Add-in

Grammarly updates or add-in conflicts are a primary cause of automatic proofing issues in Word.

Third-party proofing tools often override Word's native spelling and grammar check settings. Temporarily disabling them helps isolate the problem.

1
Access Word Add-ins

Open Word, go to 'File' > 'Options', and select 'Add-ins' from the left menu panel.

2
Manage COM Add-ins

In the 'Manage' dropdown menu at the bottom of the window, select 'COM Add-ins' and click the 'Go' button.

3
Disable the Add-in

Uncheck the 'Grammarly' add-in (and any other third-party proofing add-ins) to disable it, then click 'OK'.

4
Restart and Test

Restart Microsoft Word and check if the proofing settings remain active. If disabling fixes the issue, consider checking for a Grammarly update before re-enabling it.

Frequently Asked Questions

Why does Word keep hiding spelling errors in my document?

This is often caused by third-party add-ins like Grammarly overriding Word's native settings, a corrupted Normal.dotm template, or a specific document being formatted with 'Do not check spelling or grammar' applied to its underlying text styles.

How do I permanently stop Word from ignoring grammar errors?

Go to File > Options > Proofing. Ensure 'Check spelling as you type' and 'Mark grammar errors as you type' are checked. Next, uncheck 'Hide spelling errors in this document only' and 'Hide grammar errors in this document only' under the Exceptions section at the bottom.

Will renaming Normal.dotm delete my existing documents?

No, renaming the Normal.dotm file only resets Word's default formatting, macros, and preferences for new blank documents. Your existing saved documents and files remain completely safe and untouched.

What does the winword /r command do in Windows?

Running winword /r forces Microsoft Word to run a background setup that re-registers Word in the Windows registry. This is an effective troubleshooting step for fixing issues where Word behaves erratically or fails to launch due to registry corruption.
