You know that feeling when you're trying to describe something incredibly specific but the right word just doesn't exist? Well, honestly, it probably does. You just haven't met it yet. We've all been there—staring at a sunset or trying to explain that weirdly pleasant smell after a rainstorm—and falling back on "nice" or "refreshing" because our vocabulary hit a brick wall. Most people stick to a safe, narrow lane of about 20,000 to 35,000 words. It's functional. It gets the groceries bought. But it's also kinda boring.
English is a sprawling, messy, beautiful disaster of a language. It’s got over 170,000 words in current use, plus another 47,000 that are technically obsolete but still hanging around the edges like ghosts at a party. Some of the most fascinating obscure words are the ones that capture human experiences we thought were unnameable.
Language shapes how we think. This isn't just some artsy theory; it’s a concept known as linguistic relativity. If you don't have a word for a specific emotion, it’s harder to process it. By expanding your mental dictionary, you're basically upgrading your brain's operating system.
The Science of Rare Vocabulary and Brain Health
Why do we even care about learning obscure words anyway? Is it just to look smart at dinner parties? Maybe a little. But researchers like those at the University of Santiago de Compostela have found that a rich vocabulary is actually a protective factor against cognitive decline. It’s called "cognitive reserve." Think of it like building a bigger, more complex web in your head; if one strand breaks, the whole thing stays up because there are so many other connections.
It’s not just about memory. It’s about nuance. When you use a word like petrichor instead of "rain smell," you aren't just being fancy. You’re being precise. Precision reduces misunderstanding.
Why Some Words Disappear
Languages evolve. They're alive. Words die out because the things they describe no longer exist—like snollygoster, a 19th-century term for a shrewd, unprincipled politician (actually, maybe we should bring that one back). Other times, they just get replaced by shorter, punchier versions. But sometimes, the best words get lost in the shuffle of history simply because they’re a bit too specific for the average person's daily grind.

Take the word apricity. It describes the warmth of the sun in winter. Everyone has felt it. You’re standing in the freezing cold, but the sun hits your face and for a second, it feels like July. It’s a distinct sensation. Yet, for some reason, we stopped using the word in the mid-1600s. We traded a beautiful, singular noun for a clunky sentence. That feels like a loss.
Obscure Words That Explain Your Daily Life
Let's look at some gems that really should be more common. These aren't just "SAT words" meant to torture high schoolers. These are tools for better living.
1. Sonder
This one has gained some traction online lately, largely thanks to John Koenig’s The Dictionary of Obscure Sorrows. It’s the profound realization that every random passerby is living a life as vivid and complex as your own. They have their own heartaches, their own weird internal monologues, and their own laundry lists. It’s a cure for main-character syndrome.
2. Dysania
Ever had one of those mornings where the bed feels like a magnetic field you can't escape? That's dysania. It’s not just being tired; it’s a genuine struggle to get out of bed. It’s often used in medical contexts regarding chronic fatigue or depression, but honestly, on a rainy Monday, most of us have felt a touch of it.
3. Tsundoku
This one is a loanword from Japanese, but it fits the English-speaking world perfectly. It refers to the act of buying books and letting them pile up without reading them. It’s a specific kind of optimistic hoarding. You aren't just buying paper; you’re buying the idea of the person who would read that book.

4. Alexithymia
This is a more clinical term, but it’s incredibly useful. It describes an inability to identify and describe emotions in oneself. If someone asks "How do you feel?" and your brain just gives you a 404 Error, you might be experiencing alexithymia. Understanding the word can actually be the first step toward fixing the problem.
The Problem With Modern "Slang"
We’re in a weird spot right now. Social media is churning out new words at a breakneck pace—think rizz or gyatt—but these are often fleeting. They’re "vibes," not precision instruments. While slang is great for social bonding, it often lacks the depth of older, obscure words that were forged over centuries to describe the human condition.
How to Actually Remember New Words
Learning a list is easy. Keeping it in your head is the hard part.
You’ve gotta use them. That’s the secret. The "Use It or Lose It" rule is real. If you learn the word lethologica (the inability to remember a word), use it the next time you're stuck. Say, "Sorry, I’m having a bit of lethologica right now." It’s meta. It’s funny. It sticks.
Spaced repetition is the gold standard here. Don't cram twenty words in one night. Learn one. Use it three times in a day. Then revisit it in three days. Then a week. This moves the information from your short-term "scratchpad" memory into your long-term storage.

A Note on Being "That Person"
There is a danger here. Nobody likes a pedant. If you start dropping floccinaucinihilipilification (the act of deciding something is worthless) into every casual chat at the bar, you’re going to lose friends. Fast.
The goal isn't to sound superior. The goal is to be more expressive. Use rare words when they fit the moment perfectly, not just to show off. A well-placed rare word is like a spice; it enhances the dish. If you dump the whole jar of cumin in the soup, it’s ruined.
Bringing It All Together
Language is a playground. Most people stay on the swings, but there’s a whole jungle gym out there if you’re willing to climb. Using obscure words isn't about being an elitist; it's about finding the right key for the lock. It’s about looking at a complex world and having the right tools to describe it.
When you start noticing the psithurism (the sound of wind in the trees) or recognizing your own clinomania (the excessive desire to stay in bed), the world gets a little bit more colorful. It becomes a place with more edges, more textures, and more meaning.
Practical Steps to Expand Your Vocabulary
If you actually want to change how you speak and think, you need a system. Passive reading isn't enough.
- Audit your go-to words. We all have verbal crutches. Maybe you use the word "amazing" for everything from a good sandwich to a life-changing miracle. Find three alternatives for your most-used adjective.
- Read outside your bubble. If you only read news, read a 19th-century novel. If you only read fiction, pick up a technical manual for a hobby you don’t have. Different fields use different "dialects" of English.
- Keep a "Word Graveyard" in your phone notes. When you see a word you don't know, don't just look it up and forget it. Screen-grab it or jot it down. Review that list once a week while you're waiting for coffee.
- Focus on feelings. The most impactful rare words are usually the ones that describe internal states. Search for "untranslatable words for emotions" and see which ones resonate with your own life experiences.
Stop settling for "fine" or "okay." The English language is a massive, overstocked toolbox. Go find the weirdest wrench in the drawer and see what you can build with it. You'll find that once you have the words for things, the things themselves start to make a whole lot more sense.
Actionable Insight: Start small. Pick exactly one word from this article—maybe apricity if it's cold out, or tsundoku if you have a messy nightstand—and use it in a text message or conversation today. Don't explain it unless asked. Just let it exist in your vocabulary. Once you've used it naturally three times, it belongs to you forever. After that, go find another one. Your brain will thank you for the extra "cognitive reserve" later on.
