Microsoft Word Cuts Thesaurus Feature, Pushes AI Copilot Instead

  • Thread Author
In an unexpected, somewhat shocking turn of events, Microsoft has quietly removed the Thesaurus feature from Word, leaving writers, academics, and anyone with a penchant for expanding their vocabulary feeling flummoxed. And let’s face it, some of us are downright aghast.
As part of a larger effort to retire Smart Lookup on January 1, 2025, Microsoft Word bid farewell to its most unsung hero: the beloved built-in Thesaurus. In its place, Microsoft seems to be nudging users toward its AI-powered darling, Copilot in Word. While this transition reflects Microsoft's growing investment in artificial intelligence, the sudden departure of such a simple, yet vital, tool has left many long-time Word users bewildered.
Let’s unpack what’s going on and why this change matters more than you might initially think.

Bye-Bye Thesaurus: What Has Changed?​

For decades now, Microsoft Word’s Thesaurus feature operated like a trusty sidekick for wordsmiths everywhere. Just highlight a word, right-click, and voilà: you’d have a list of synonyms (and sometimes antonyms) faster than you could mutter, “Is there a better word for ‘bewildering’?” Thanks to Word’s Smart Lookup, this function was seamless—definitions and contextual suggestions were just a click away.
However, as of January 2025, attempting to invoke Smart Lookup results in a popup that coldly informs users the feature has been deprecated. There’s no immediate, overt replacement for the Thesaurus functionality in Word. Instead, users are expected to pivot to external solutions like web browsers or dig into Microsoft’s Copilot, assuming they’re paying for the additional AI-powered perks.
Basically, Microsoft just pulled off the software equivalent of taking your favorite slippers and handing you a pair of sneakers with built-in AI that say, "No, trust me, you'll thank me later."

Why Did Microsoft Remove the Thesaurus?​

The short- and sweet answer? Likely to boost adoption of Copilot in Word and underscore its value in Microsoft 365 subscriptions. This isn’t just speculation—the timing aligns suspiciously well with Microsoft raising the price of Microsoft 365 for the first time in over a decade. It also comes on the heels of Microsoft’s introduction of Copilot Credits, which lets you use its AI helper across Windows 11, Microsoft Office apps, and a few other services.
While Microsoft hasn’t outright blamed the price increase on Copilot, all signs point to their strategy of positioning AI as central to the software suite’s future. Retiring smaller features like Smart Lookup clears the road for Copilot and might even play a role in subtly nudging skeptical users toward believing that paying for AI features is worth it.
Let’s not forget: Microsoft has pumped enormous investment into AI after partnering with OpenAI (the creators of ChatGPT). With features like Copilot now integrated deeply into Microsoft Word & Excel, the removal of less flashy tools could be a way to shine a spotlight on what Microsoft views as their premium offering.
Simply put: if Thesaurus was the old jalopy, Copilot is Microsoft’s shiny Tesla, and they want to sell you that ticket to the future. But is it ready?

Why Writers Everywhere are Stunned (and Annoyed)​

It’s fair to say most casual Word users—students writing essays, for example, or professionals penning emails—may not immediately miss the Thesaurus. But for advanced users? This change strikes deep.
The standout feature of Word's built-in thesaurus wasn't just its simplicity; it was the fact that everything happened right where you were working. Want to swap out "huge" with "monumental"? You didn’t need to break your workflow to open a browser or fiddle with add-ons.
Here's what's problematic about the alternatives:
  • Copilot Usage: Yes, Copilot can suggest synonyms, rephrasing, and other enhancements, but it requires a Microsoft 365 subscription with AI access. Not everyone is on the premium plan.
  • Web Browsers: While Google or any online Thesaurus can handle the job, let’s not pretend jumping back and forth between Word and your browser doesn’t interrupt your momentum.
  • Third-Party Apps: Tools like Grammarly continue to encroach upon Microsoft’s turf, but some users simply don’t want third-party extensions in their workflow.
The change marks a subtle shift in how Word prioritizes advanced features. Removing these bread-and-butter tools clearly signals that Microsoft sees AI as the centerpiece of its suite going forward. But should they be counting on Copilot’s success to justify alienating a portion of their customers?

What is Copilot, and Does it Fill the Void?​

If you’ve been living under an anti-tech rock, Copilot is Microsoft’s AI-infused personal assistant for Microsoft 365 apps. It uses natural language processing to help you perform complex tasks with just a prompt. Need a summary of a document? Copilot’s got you covered. Want your spreadsheet analyzed or that bullet-point list converted into professional prose? Enter Copilot again.
However, for Thesaurus replacement scenarios, its advantage sits squarely in its ability to contextualize. It doesn’t just toss bland synonyms into your lap—it attempts to interpret phrases with nuance. For example, where the previous Thesaurus might suggest “happy” could mean “joyful” or “content,” Copilot could infer that your sentence structure needs something like “elated” or “satisfied.”
While intuitive, this places an AI-based engine where a no-fuss dictionary once existed. And for folks who valued simplicity over smartness, this pivot will certainly leave gaps. Moreover, the requirement of subscription tiers complicates accessibility.

Broader Implications for Microsoft Word & Users​

Removing Word’s thesaurus doesn’t just mark the death of a feature—it highlights where the software industry is headed. AI-driven solutions are fast replacing traditional tools, whether users actively choose them or not.
The danger here, however, is that Microsoft risks losing the trust of loyal users who rely on stability rather than constant change. Tugging features away without consensus isn’t just inconvenient—it sets a precedent for similar removals in the future.
Windows aficionados might wonder: what’s next on the chopping block? Can we expect spell checkers to go obsolete because “Copilot can do it better”? When is simplicity no longer an option?

Here’s How to Keep Your Writing Sharp Without the Thesaurus​

For now, users who’ve relied on Word’s built-in thesaurus will need to make do with these practical alternatives:
  • Using Browser-Based Dictionaries & Thesauruses: Merriam-Webster and Thesaurus.com work like charm, albeit slightly less conveniently.
  • Keyboard Shortcuts for Search: Quickly search synonyms via Bing (Microsoft’s favorite) directly on Edge or your preferred browser.
  • Third-Party Apps: Grammarly, ProWritingAid, and Hemingway App are built for wordsmiths craving tools that elevate vocabulary and sentence structure.
  • Manual Techniques: Sometimes you can just crack open a paperback thesaurus. Shockingly, they still exist!

Final Thoughts: Goodbye, Old Friend​

With Word’s thesaurus gone, we’re left questioning whether all innovation is necessarily progress. For some users, Copilot will be a dream come true—a Swiss-army knife for productivity. For others, the removal of features like Smart Lookup scratches away the edges of loyalty bit by bit.
Is Microsoft overplaying its hand by focusing all-in on AI-powered products? Only time will tell... Until then, let’s keep our thesauruses near and dear. Or should we say invaluable, precious, or indispensable?
What do you think about this change? Are you excited to embrace Copilot, or are you lamenting the loss of a trusted feature? Let us know on the forums.

Where do we complain? This is making me want to switch to another word processor. I don’t want AI anything.
 

You’re not alone—this move by Microsoft has sparked quite a bit of frustration, especially among users who don’t want AI taking over basic, reliable tools. While Microsoft hasn’t set up a dedicated “complaint inbox” for the Thesaurus removal, you do have a few ways to make your voice heard:

1. Microsoft Feedback Hub​

If you’re using Windows, open the Feedback Hub (just search for it in the Start Menu). Submit your complaint under “Microsoft Word” or “Office” and clearly state you want the built-in Thesaurus (and Smart Lookup) restored. The more upvotes feedback gets, the more attention it draws.

2. Microsoft Word In-App Feedback​

In Word, go to Help → Feedback (or File → Feedback, depending on version). Choose "Send a suggestion" or "I don't like something" and explain why removing core features in favor of AI is a dealbreaker for you.

3. Microsoft Community and Support Forums​

Post about your frustration on the official Microsoft Community:

4. Social Media​

Tag @Microsoft, @Office, or @MicrosoftHelps on X (Twitter) or respond to relevant posts on LinkedIn or Facebook. Public feedback often gets attention quickly, especially if you’re concise and point out you might switch to other word processors.

5. Consider Alternative Word Processors​

If you’re seriously considering switching, solutions like LibreOffice, WPS Writer, or even Google Docs still include basic (non-AI) thesaurus tools. Sometimes the best protest is showing Microsoft you’ll take your business elsewhere.

You’re absolutely justified in wanting simple, no-nonsense tools that work. Don’t let Microsoft’s “AI-or-nothing” push go unchallenged—let them know how you feel, and don’t hesitate to move to software that respects your workflow. If you need recommendations for alternative word processors with a good, local thesaurus, just ask!
