Nothing disrupts the flow of writing quite like a spelling error. If you're using Microsoft Word on a Mac, you'll want to ensure your spell check is up and running to catch those pesky typos. This guide will walk you through how to turn on spell check in Word on your Mac. You'll be a spelling superhero in no time!
Getting Started with Spell Check in Word
Before diving into the settings, let's get familiar with how spell check works in Word. Essentially, Word reviews the text in your document, highlighting misspelled words and suggesting corrections. This feature is a lifesaver when you're typing fast and don't have time to manually proofread every line.
Spell check can work in two ways: automatically as you type, or manually when you run a review. Both methods have their benefits. Automatic spell check is great for catching mistakes on the fly. Manual review is thorough, ensuring you don't miss anything. So, how do you activate these tools on your Mac? Let's take a look.
Enabling Automatic Spell Check
Automatic spell check is a feature that highlights spelling errors as you type. Here's how you can turn it on:
- Open Microsoft Word on your Mac and navigate to a new or existing document.
- Click on the Word menu in the top left corner next to the Apple icon.
- Select Preferences from the dropdown menu. This will open a new window.
- In the Preferences window, click on Spelling & Grammar.
- Ensure that Check spelling as you type is checked. If it's not, click to enable it.
- Close the Preferences window. Your changes will automatically save.
Now, as you type, Word will underline misspelled words with a red squiggly line, making it easy to spot and correct mistakes as they happen.
Running a Manual Spell Check
While automatic spell check is convenient, sometimes you need a more thorough review. This is where manual spell check comes in. Here's how to activate it:
- In your document, go to the Tools menu in the top toolbar.
- Select Spelling and Grammar from the dropdown.
- This will open a new pane on the right, showing the first misspelled word in your document.
- Word will suggest corrections in the pane. Select the correct word, and click Change to fix the error.
- Continue through your document until you've reviewed all errors.
Manual spell check is perfect for those final proofreads before sending important documents. It ensures nothing slips through the cracks.

Customizing Your Spell Check Experience
Did you know you can customize how Word handles spell check? Depending on your needs, you might want to adjust a few settings:
- Ignore Uppercase Words: If your document includes a lot of acronyms or proper nouns, consider enabling this setting to prevent unnecessary corrections.
- Ignore Words with Numbers: Useful for technical documents where numbers and letters might appear together.
- Ignore Internet and File Addresses: This prevents Word from flagging URLs or file paths as errors.
These options are found in the same Spelling & Grammar section in Preferences. Tweak them according to your document's needs to streamline your spell check process.
Adding Words to Your Custom Dictionary
Ever get tired of Word flagging your company name or industry-specific terms as misspelled? You can add these words to a custom dictionary so they're recognized as correct in future documents.
- When Word flags a word, right-click on it.
- Select Add to Dictionary from the context menu.
That's all there is to it! Word will remember these words, saving you time and frustration in the future.
Using Grammar Check Alongside Spell Check
While spell check is fantastic for spotting typos, grammar check takes it a step further by highlighting grammatical issues. To ensure your document is polished, enable grammar check:
- Head back to Preferences under the Word menu.
- Select Spelling & Grammar.
- Ensure Check grammar as you type is checked.
Now, Word will underline grammar issues with a blue squiggly line. With both spell and grammar check activated, your writing will be error-free and clear.
Dealing with False Positives
Sometimes, Word might flag a word that's actually correct. This is common with names, technical terms, or foreign words. Here's what you can do:
- Ignore Once: Right-click the word and select Ignore Once if it appears rarely in your document.
- Add to Dictionary: For frequently used terms, add them to your custom dictionary as described earlier.
This ensures Word doesn't repeatedly flag the same words, simplifying your editing process.
Spell Check Doesn't Work? Troubleshooting Tips
If spell check isn't working, don't panic. Here are some steps to troubleshoot:
- Ensure spell check is enabled by revisiting the Spelling & Grammar settings.
- Check your Mac's language and region settings, as these can affect spell check.
- Restart Word, or even your Mac, to refresh the system.
If it still doesn't work, consider updating Word or reaching out to Microsoft support for further assistance.
