Spell Check Issues with Uppercase Words in Microsoft Word

To get Microsoft Word’s spell check to recognize uppercase words, simply navigate to the ‘File’ tab, select ‘Options’, then ‘Proofing’. Under ‘When correcting spelling in Microsoft Office programs’, uncheck the box that reads ‘Ignore words in UPPERCASE’. Voila! Your all-caps words will now be scrutinized by the ever-vigilant spell check.

After completing this action, Microsoft Word will include uppercase words in its spell check, ensuring that all parts of your document are free of spelling errors, regardless of their case.


When it comes to typing up documents, Microsoft Word is the go-to for many. It’s trusted, user-friendly, and equipped with a handy spell check feature that keeps our writing error-free—or so we hope. But have you ever noticed that sometimes, words in uppercase slip through the spell check net? It’s not a glitch; it’s a default setting. The rationale behind this is simple: uppercase words are often acronyms or initialisms, like NASA or ASAP, which wouldn’t be found in a standard dictionary.

But what happens when you’re typing a title or a heading, and you need those uppercase words to be just as error-free as the rest of your text? Well, that’s where tweaking a few settings comes in handy. Whether you’re a student, a professional, or just someone who takes pride in their written word, knowing how to adjust these settings can make a big difference. Let’s dive in and get those uppercase words in check!

Finally, if you’re collaborating on a document, ensure that all parties are aware of these settings to maintain consistency across the board.
