How to Fix Word Spell Checker Not Working [4 Easy Ways]
Microsoft Word's built-in spell checker ensures that your documents are free of spelling and grammatical errors. If this feature ever stops working, errors in your document will not be flagged. This means you run the risk of ending up with documents that contain grammatical errors.
Several things can cause Word's spell checker to not work. You may have manually turned off spell check, an incorrect language may be specified in Word's settings, or your current document may have an exception for spell check.
Once you fix these issues, spell check will go back to work flagging all spelling and grammar issues.
