Enable Built-in Proofing and Grammar Settings

Although Word 2021 lacks the full Microsoft Editor found in Microsoft 365, you can still enable robust built-in spelling, grammar, and refinement checks.

Word 2021 relies on classic Proofing tools rather than the newer Microsoft Editor pane. By adjusting your Proofing options, you can force the application to check for spelling, grammar, and stylistic issues like double spacing as you type.

1
Open Word Options

Launch Word 2021, click on 'File' in the top ribbon, and select 'Options' at the bottom left of the screen.

2
Navigate to Proofing

In the Word Options dialog box, click on 'Proofing' in the left-hand menu pane.

3
Enable As-You-Type Checks

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

4
Configure Writing Style

Change the 'Writing Style' dropdown menu to 'Grammar & Refinements', then click the 'Settings' button next to it.

5
Enable Specific Rules

In the Grammar Settings window, scroll to find specific rules like 'Spacing' under the Punctuation Conventions section. Check the boxes you need, and click 'OK' to apply the changes.

Frequently Asked Questions

Why is the Microsoft Editor tab missing in Word 2021?

The Microsoft Editor pane is a premium feature exclusive to Microsoft 365 subscription plans. Because Word 2021 is a one-time purchase product, it only includes the classic Proofing tools found in File > Options, not the dedicated Editor interface.

How do I fix unwanted double spaces in Word 2021?

Go to File > Options > Proofing. Under Writing Style, choose 'Grammar & Refinements' and click the 'Settings' button. Scroll down to find the 'Spacing' option under Punctuation Conventions and enable it. Unwanted spaces will now be marked with a blue double underline in your document.

Can I get Microsoft Editor for free?

Yes, the basic version of Microsoft Editor is available for free if you use Word for the web (Word Online) or by installing the free Microsoft Editor browser extension for Microsoft Edge or Google Chrome.

Why aren't my spelling errors getting red underlines?

Your background spelling check setting might be disabled. To fix this, navigate to File > Options > Proofing, and ensure the checkbox for 'Check spelling as you type' is ticked.
