How to Find Spell Check in Microsoft Word (Every Version)

Spell check is one of Word's most relied-upon features — and also one of the most frequently misplaced, especially after a software update or when switching between versions. Whether it's gone quiet on you or you've never pinpointed exactly where it lives, here's a clear map of where to find it, how it works, and what controls its behavior.

Where Spell Check Lives in Microsoft Word

In most modern versions of Word, spell check operates in two ways simultaneously: automatically in the background as you type, and on demand when you run a manual check.

The Review Tab: Your Starting Point

The most direct route to spell check is the Review tab in the top ribbon. Click it, and you'll see a "Spelling & Grammar" button on the far left of the toolbar. Clicking this launches a full document check — Word scans from the cursor's current position and flags each potential error in a task pane or dialog box (depending on your version).

Keyboard shortcut: Press F7 at any time to launch the spell checker instantly, regardless of which tab you're on. This works across nearly all desktop versions of Word and is the fastest path when you're mid-document.

The Automatic Underline System

The red squiggly underline beneath a word is Word's real-time spell check in action. Right-clicking any underlined word produces a context menu with:

• Suggested corrections
• "Ignore" or "Ignore All" options
• "Add to Dictionary" (to stop flagging a correctly spelled term Word doesn't recognize)

The blue or green underlines you might also see are separate — those indicate grammar or style suggestions, not spelling errors. Word has increasingly blended spelling and grammar into a unified proofing system, particularly in Microsoft 365.

How to Access Spell Check Settings

Finding where to turn on spell check, customize it, or troubleshoot it requires going deeper than the Review tab.

Through Word Options

Go to File → Options → Proofing. This is the control center for everything related to spelling and grammar. From here you can:

• Toggle "Check spelling as you type" (the red underline behavior)
• Enable or disable "Mark grammar errors as you type"
• Set exceptions for specific documents
• Manage your custom dictionary — the list of words you've added manually
• Choose the writing style (Grammar Only vs. Grammar & Refinements in Microsoft 365)

If spell check has stopped working in a document, this is the first place to check. A common culprit is the "Hide spelling errors in this document only" checkbox — it's a per-document setting that can be enabled accidentally.

Language Settings Matter More Than You'd Think

Word's spell check is tightly linked to proofing language. If text is formatted with a language that doesn't match your installed proofing tools — or is set to "Do not check spelling" — Word will silently skip it. 🔍

To check this: highlight the text in question, go to Review → Language → Set Proofing Language, and confirm it's set to the correct language with spell check enabled.

Spell Check Across Different Versions of Word

The feature works consistently across versions, but its visual location and behavior shift slightly depending on what you're running.

The shift to the Editor pane in Microsoft 365 is worth noting. What used to be a simple spell-check dialog has expanded into a broader writing assistant that scores your document, flags spelling, grammar, clarity, conciseness, and more — all in one panel. If you're looking for the old-style experience, it's still accessible via the same F7 shortcut or the Review tab, but the interface is now panel-based rather than a pop-up window.

When Spell Check Isn't Working

A few situations reliably cause spell check to go silent: ✏️

• Text is formatted as a non-installed language — Word won't check what it doesn't have proofing tools for
• The document has spell check exceptions enabled — check File → Options → Proofing
• Custom dictionary conflicts — a word added incorrectly to your dictionary won't be flagged
• Office installation is missing proofing tools — especially common with volume-licensed or stripped-down installations
• The text box or object isn't checked — spell check in Word doesn't automatically cover text inside shapes or certain embedded objects

For persistent issues, running Office Repair (via Control Panel → Programs on Windows) often resolves proofing tool problems that settings alone can't fix.

What Controls Your Experience

How useful Word's spell check actually is depends on several variables that differ from user to user:

• Which version of Word you're running — Microsoft 365 subscribers get continuous updates to the Editor's grammar and style engine; perpetual license users (2019, 2021) have a fixed feature set
• Your installed proofing languages — multilingual users may need to install additional language packs through Office settings
• Document origin — files shared from other users or created in older formats sometimes carry language or exception settings that override your defaults
• Whether AutoCorrect is involved — AutoCorrect and spell check are related but separate systems; AutoCorrect fixes errors silently as you type, while spell check flags them for your review

The depth of grammar checking also varies. Microsoft 365's Editor has grown into a much more opinionated writing tool than the basic grammar check in older standalone versions — which means it surfaces more suggestions, but also more noise depending on your writing style and document type.

How well any of these features serve you comes down to the specifics of your setup, the version you're on, and what kind of checking you actually need from the tool.
