Ever notice how some everyday objects or sensations seem to lack a name? You use them, experience them, and see them all the time—yet you never stop to think about what they’re actually called. And when you have to talk about them, you end up using a bunch of words to describe them rather than the specific word. Well, prepare to be amazed: here are twelve things you never knew had their own official names!
Petrichor: The smell of rain

That amazing earthy smell after a fresh rainfall? It’s called petrichor. The scent is produced when rain interacts with dry soil, releasing aromatic compounds into the air.
The term was coined by Australian scientists in 1964, combining the Greek words petra (stone) and ichor (the fluid said to run through the veins of the gods). It’s so distinct that some companies have even tried to bottle it as a fragrance. Would you buy one?

Your kids or grandkids will love this fact—because they all love this little thing! Do you know that small plastic table in the center of a pizza box? It’s officially called a tent, and its job is to prevent the box lid from collapsing onto your delicious pizza.
Introduced in the 1980s, this small invention has saved countless pizzas from disaster, keeping the cheese intact for your enjoyment. Now, once it’s removed, that’s a kid’s toy for sure!
Columella Nasi: The space between your nostrils

That little strip of tissue separating your nostrils? It has a fancy name: columella nasi. It’s crucial for maintaining the shape of your nose and is often involved in rhinoplasty procedures.
The term originates from Latin, where columella means "little column"—which makes perfect sense since it's the little column keeping your nose upright!
Dysania: The struggle to get out of bed

If you find it nearly impossible to get out of bed in the morning (pretty much like everyone else), you might have dysania. While this is not strictly a medical condition, the term perfectly captures that all-too-familiar feeling of wanting to stay under the covers forever.
It comes from Greek, with dys- meaning "difficulty" and -ania referring to a state of mind or struggle. It really is a struggle sometimes!
Griffonage: Messy, illegible handwriting

If your handwriting looks like a doctor’s prescription, you might be guilty of griffonage.
This word refers to scrawled, unreadable handwriting—the kind that leaves people squinting and guessing. It comes from French, where griffonner means "to scribble." So… are you guilty of it?
Lunule: The white crescent on your nail

Look at your hand—your nails, specifically. Do you notice that little white, half-moon shape at the base of your nail? That part is called a lunule.
It’s actually part of the nail’s root and is most visible on the thumbs. The name comes from the Latin word luna, meaning "moon," because of its crescent shape. A healthy lunule is a sign of good nail growth!
Glabella: The space between your eyebrows

The smooth patch of skin between your eyebrows has a name: the glabella. It’s the area where frown lines often form and is a frequent target of Botox treatments.
The word comes from the Latin glabellus, meaning "smooth." Next time someone wrinkles their forehead, impress them by pointing out their glabella in action!
Punt: The dent at the bottom of a wine bottle

That deep indentation at the base of your wine bottle? It’s called a punt. While its exact purpose is debated, it’s believed to add structural integrity and aid in pouring.
Some say it also makes the bottle look more expensive! The origin of the word is uncertain, but it has been used in glassmaking for centuries. Pour that wine—now that you know all about it!
Lemniscate: The infinity symbol

The beautiful, never-ending figure-eight symbol that represents infinity is officially called a lemniscate.
It has been used in mathematics, philosophy, and even tattoos as a symbol of endless possibilities. The name comes from the Latin lemniscus, meaning "ribbon"—a perfect description of its flowing shape.
Collywobbles: That fluttery feeling in your stomach

Have you ever had "butterflies" in your stomach before a big event? You know, that nervous, fluttery sensation is actually called the collywobbles. It’s your body’s way of responding to excitement, anxiety, or nervous anticipation.
The term dates back to the 19th century and is believed to be a playful alteration of "colic," a word used for stomach pain—naturally.
Snellen Chart: The eye test chart

We’ve all been to the eye doctor, hoping we wouldn’t need glasses. Yet the eye test chart is right there, waiting to issue its verdict. That chart you stare at during an eye exam—with rows of letters that get progressively smaller—is called a Snellen chart.
It was developed in 1862 by Dutch ophthalmologist Dr. Herman Snellen and remains a standard tool for testing vision to this day.
Aphthongs: Silent letters in words

Ever wondered why "knight" has a silent ‘k’ or "what" has a silent ‘h’? Those unpronounced letters are called aphthongs. The word comes from Greek, where "aphthongos" means "voiceless" or "speechless." Quite accurate, right?
English is full of them, and they make spelling just a little trickier—especially if it’s not your first language!
