Step 1: Open the ‘Review’ tab

Navigate to the ‘Review’ tab on the ribbon at the top of the Word document.

The ‘Review’ tab is where all the tools related to document proofing live. Not only will you find the spell check feature here, but you’ll also get access to the thesaurus, word count, and other useful features.

Step 2: Click on ‘Spelling & Grammar’

Select the ‘Spelling & Grammar’ option from the ‘Review’ tab.

This will initiate the spell check process. Word will begin scanning your document, highlighting potential errors as it goes along.

Step 3: Review suggestions and make corrections

Review the suggested corrections and choose to either accept or ignore them.

As Word detects errors, a sidebar will appear with suggestions. You can click on each suggestion to see more details and choose the action you want to take.

Step 4: Complete the spell check

Conclude the spell check by going through all suggestions until Word confirms that the check is complete.

Once you’ve gone through all the suggestions, Word will display a message indicating that the spell check is finished. You can then rest assured that your document is free of spelling errors.

Contextual LimitationsSometimes, Word may not understand the context and suggest incorrect replacements.
OverrelianceRelying too heavily on spell check might hinder your ability to spot errors independently.

Additional Information

While the spell check feature in Microsoft Word for Office 365 is robust, there are some additional tips and insights that can enhance your experience.

Additionally, you can set the language preference for spell check, which is useful for bilingual or multilingual documents. Another handy feature is the ‘Read Aloud’ tool, found in the same ‘Review’ tab, which reads your document out loud, helping you catch errors that you might have missed visually.
