Introduction: A Day for Word Lovers Everywhere
If you’ve ever spent a few extra minutes finding the perfect word—not just any word, but one that fits like a glove—then National Thesaurus Day is your time to shine. Celebrated every year on January 18, this playful yet profound holiday honors the art of language, the joy of synonyms, and our collective love for expression.
Whether you’re a writer, teacher, student, or office communicator, Thesaurus Day is more than a nod to Roget’s classic invention—it’s an opportunity to rediscover words, explore nuance, and celebrate creativity in communication.
At Riya’s Blogs, we believe every holiday is a chance to connect meaningfully—and Thesaurus Day is no exception. From thesaurus day messages that make your team chuckle to wordplay puns and synonym challenge captions, this is the one day you’re officially allowed (and encouraged!) to be a little verbose.
The Story Behind Thesaurus Day
National Thesaurus Day is celebrated on January 18, the birthday of Peter Mark Roget, the brilliant British physician and lexicographer who published Roget’s Thesaurus of English Words and Phrases in 1852.
Roget believed that language had the power to clarify thought. His thesaurus wasn’t merely a collection of synonyms—it was an organized reflection of how ideas relate to one another.
So when you celebrate Thesaurus Day, you’re not just celebrating words; you’re honoring the legacy of understanding, creativity, and expression.
Why Celebrate National Thesaurus Day?
Because words matter.
Because communication is an art.
Because every synonym is a small miracle that keeps language alive and evolving.
Here’s why it’s worth celebrating:
- For Writers & Copywriters: A reminder that words are your tools—and your playground.
- For Students: A fun way to expand vocabulary beyond “nice,” “good,” or “bad.”
- For Offices: A chance to turn language into laughter with office word games or group ecard word challenges.
- For Teachers: The perfect day for an interactive word-of-the-day template or classroom synonym race.
So yes, Thesaurus Day isn’t just for word nerds—it’s for everyone who believes words have power.

Office Word Game Ideas for Thesaurus Day
Turn your workplace into a word carnival with these fun, easy-to-run office word games:
1. Synonym Scramble
Each person gets a simple word (like happy, strong, or teamwork). Everyone lists as many synonyms as possible in one minute. The person with the most accurate synonyms wins.
2. Word Ladder
Start with one word and change one letter at a time to create a new one (e.g., word → ward → warm → worm). Great for group brainstorming!
3. Copywriter Appreciation Corner
Ask team members to share their favorite well-written line or ad copy. Discuss how word choice changes tone and emotion.
4. Guess the Word (Slack Version)
Post a definition or a series of synonyms in Slack and ask the team to guess the original word. For example:
“Hint: joyful, jubilant, content. What’s the word?”
(Answer: happy).
5. Office Pun Contest
Challenge your team to come up with the best wordplay puns. From “I’m reading a book on anti-gravity—it’s impossible to put down” to “I’m thesaurus-ly excited!”
For Schools and Classrooms
In schools, Thesaurus Day can be a gateway to loving language.
Activity Ideas:
- Synonym Scavenger Hunt: Give students a list of words and have them find three synonyms each.
- Word-of-the-Day Board: Every class contributes a new word and uses it in a sentence.
- Creative Writing Corner: Students rewrite short stories using different synonyms to see how tone changes.
Tone for Schools:
Keep it playful and educational. Focus on curiosity, discovery, and the magic of words.
For Offices and Teams
At work, language defines culture—emails, greetings, meeting notes, even inside jokes.
Ways to Celebrate:
- Start the morning with a “Word of the Day” on your company Slack.
- Host a copywriter appreciation shout-out for your content team.

These mini-celebrations are low-cost, high-fun ways to make the day unforgettable.
Create Your Own Word-of-the-Day Template
A Word-of-the-Day Template is an easy yet powerful way to extend the celebration throughout January.
