11 common objects that are never called by their proper names

While we typically go about life describing the end of our shoelaces as ‘the end of the shoelace’ or the whites of the egg as ‘egg whites’, these things, and many more, have names of their own, even if they are not always widely known or used. Let’s have a look at 11 common things that have proper names, even if no one uses them.

The little plastic or metal tip at the end of shoelaces or drawstrings is there to prevent the fibres from fraying, and to make it easier to pass the lace or drawstring through a hole. Its proper name is ‘aglet’, from the French aguillette, meaning ‘needle’, a reference to its use in helping to thread the string through the hole.

Erasers at the end of wooden pencils are not usually glued together, but they are instead held together by a little metal band. This band is called a ‘ferrule’—from Medieval Latin viriola or ‘little bracelet’—and the term can be used for any metal band that strengthens or fastens a joint, such as those used in handles, to hold brush bristles, or to secure a connection between two cables.

The ‘little plastic table on the pizza’ is quite a long name for something aptly named ‘pizza saver’, but no one seems to really care. It was invented in 1974 by an Argentine pizza maker, who named it SEPI or separador de pizza (‘pizza separator’). In America, it was patented as a ‘package saver’ in 1985, though it was later renamed ‘pizza saver’.

Most mathematical symbols have proper names that are not regularly used, and the division sign is no exception. It was officially introduced into mathematics as a symbol of division in 1659 by the Swiss mathematician Johann Rahn in his influential work Teutsche Algebra. This sign is called an ‘obelus’, from the Greek obelos, meaning ‘sharpened stick’ or ‘skewer’, as it was initially used as a pointer for questionable passages in a text.

Paper cups and their corresponding cardboard sleeves to protect our hands from the heat or the cold are relatively new, but their proper names are not—at least, the name for the cardboard sleeve. This holder is called a ‘zarf’, an Arabic (zuruuf) and Turkish (zarflar) word used for ornamented cup holders, usually made from metal. The materials and the details of the zarf have changed, but the purpose still remains.

Do we need a more technical term than ‘armhole’ for a hole meant for an arm to go through? Maybe not, but the technical term still exists. An ‘armscye’ (pronounced arm-sigh) is the proper term used in sewing and patterns to describe the opening on a garment where the sleeve is attached. The word is a compound of ‘arm’ + scye, a Scots word meaning ‘opening’. So, in the end, ‘armscye’ just means ‘armhole’.

We often use the words ‘railing’ or ‘handrail’ when talking about a staircase, but these terms only describe the top portion of it, not the pillars that support the handrail. The pillars and the rail altogether are called a ‘banister’, a corruption of the word baluster, derived from the Italian balaustro. The term originally was used for the pillars, but eventually came to mean the entire structure.

Not all beverage foams are equal. The foam on top of alcoholic beverages, in particular, is called ‘barm’, a term derived from Old English beorma, meaning ‘yeast’ or ‘leaven’, and it's mainly used for the effervescence of fermented liquors such as beer, ale, or wine.

Did you know that the white (or clear) part of the egg is called the ‘albumen’? The term entered English as a loan from Latin, where _albumen_—from albus, ‘white’—was used in the same way. Though it is not widely used in everyday life, it’s still the correct term for that part of the egg.

As a rule of thumb, you should always assume that all marks, symbols, and strokes in calligraphy have a proper name, even if it's not often used. When it comes to the lowercase letters ‘j’ and ‘i ’, the little dot on top is not a dot, but a ‘tittle’. This name comes from the Latin _titulus_—meaning ‘title’, ‘inscription’, or ‘small mark’—and was initially used by scribes to distinguish these letters in their cramped writing.

If you ever got lost in the mall or the museum, you must have come across a map that marked your location using an arrow or a pointer, usually accompanied by the phrase ‘you are here’. Well, that pointer is called an ‘ideolocator’, a combination of the Greek idea, a ‘mental image, concept, or visual representation’ (in this case, the pointer), and the Latin locatus, meaning ‘to place’ (the specific location on the map). For the sake of convenience, we will keep calling it the ‘you are here’ sign.

The 12 longest-living animals on Earth (and how they cheat time)

Nature doesn’t just create beauty, it crafts survival miracles. While most animals have short lives, a rare few have mastered the art of staying alive for centuries, even millennia. These aren’t just long-lived creatures; they’re nature’s ultimate time travelers. From the frozen depths of the oceans to the darkest corners underground, they’ve developed bizarre, brilliant strategies to cheat death. Get ready to meet 12 animals whose lifespans will absolutely blow your mind.

Record age: up to 15,000 years

This unassuming sea sponge thrives in the freezing waters of Antarctica, where temperatures hover around 28.6 °F—so cold that biological processes hit the brakes. In such icy conditions, metabolism slows to a crawl, allowing these sponges to live for thousands of years.

Some have reached impressive sizes of over 3 feet tall and have been around since mammoths were still thundering across the tundra. They don’t move, they don’t stress, and they barely change, just quietly existing while centuries pass them by. Their secret to extreme longevity? Glacial patience, deep-sea stillness, and a lifestyle that redefines "low-maintenance".

Age: technically… infinite

This tiny jellyfish, no bigger than a fingernail—less than 0.2 inches—is like the ocean’s very own Benjamin Button. What makes it truly extraordinary is its ability to rewind its life story, flipping back to a youthful, juvenile stage whenever it wants. While it’s not completely invincible (predators and other threats are still very real), if left undisturbed, it can keep hitting the reset button on aging indefinitely, making it one of the most fascinating "time-benders" in nature.

Record age: 507 years

In 2006, a special clam was discovered buried deep in the seabeds of the North Atlantic. Scientists were able to determine that it had been there since at least 1499—that’s centuries before the United States was even a thought! This ancient marvel, nicknamed "Ming", was able to perfect a slow-and-steady approach to life. Growing at a snail’s pace and barely budging, Ming’s sedentary lifestyle turned out to be a brilliant strategy for beating the clock. Who knew doing almost nothing could be the ultimate secret to longevity?

Record age: estimated 392 years

These sharks aren’t your average ocean cruisers—they can stretch over 20 feet long and weigh up to 2,200 pounds. But what’s really mindblowing is how slowly they move, like they’re in a permanent state of deep relaxation. Living in the icy Arctic waters, these giants don’t hit adulthood until they’re about 150 years old, and some can glide through the depths for nearly 400 years. Imagine that! These ancient swimmers were already around before America declared independence... and they are still out there, silently roaming the seas!

Record age: over 211 years

This whale is a true ocean giant, stretching up to 60 feet long and weighing a staggering 200,000 pounds. But what makes it stand out isn’t just its size but its age. Some of these majestic creatures carry harpoons from the 1800s still lodged in their skin, like walking history books. Just picture living so long that you’re literally carrying outdated technology embedded in your body—talk about being a time traveler of the seas!

Record age: 200 years

Spanning the chilly Pacific coastline from California all the way up to Alaska, this spiky little ball—about 7 inches across—is full of surprises. It munches on algae and calls the deep, dark ocean its home, thriving at depths of up to 300 feet. Don’t let its size fool you: this prickly creature is a true elder of the cold seas, quietly outliving many ocean neighbors while keeping a low profile. A tough, slow-living veteran wrapped in spikes!

Record age: 226 years

Meet Hanako, a legendary Japanese koi who swam through life for an astonishing 226 years. Scientists discovered how old she was by studying the rings on her scales, much like counting the growth rings of a tree. These colorful, ornamental fish aren’t just symbols of good fortune; they’re also secret long-lifers with the potential to celebrate over two centuries of birthdays, as long as they get the right care and a peaceful pond to call home.

Record age: 190 years

Jonathan is a male tortoise living on the remote island of Saint Helena in the South Atlantic Ocean. He was born back in 1832, and he’s still happily chomping lettuce and soaking up the sun today. Weighing in at more than 400 pounds and measuring around 3 feet long, Jonathan holds the title of the oldest known living land animal on the planet. If he could share tales, they’d span nearly two centuries of history. Imagine that!

Record age: 152 years

This ancient-looking fish, with its whisker-like barbels, looking like a tiny underwater submarine, prowls the lakes of North America. It can reach an impressive length of up to 7 feet and weigh around 200 pounds. These slow-living creatures don’t rush into adulthood—they start breeding only around age 20—and then take their time cruising through life at a leisurely pace. Believe it or not, one legendary catch in Wisconsin was estimated to be over 150 years old!

Record age: over 90 years

This chunky, night-loving parrot from New Zealand is a true oddball—it can’t fly, snores like a grumpy grandpa, and smells like fresh flowers. Despite its quirks, this bird boasts an impressively long lifespan. Sadly, it teeters on the edge of extinction. The oldest known kakapo, affectionately named Richard Henry, lived 90 years, earning him the title of the charmingly eccentric elder statesman of the avian world.

Record age: 37 years

This tiny, kooky rodent—barely 3 inches long and just over an ounce in weight—could’ve been cast straight from a sci-fi apocalypse flick. Dwelling in vast underground colonies across Africa, it’s practically invincible to cancer, pain, and the usual effects of aging. Scientists are fascinated by this little marvel, even if it’s not winning beauty contests anytime soon. Its superpowers make it a star in longevity research!

Record age: estimated 100+ years

Lobsters have a totally different rulebook than us when it comes to aging. They don’t really grow old; they just keep getting bigger and bigger. Some giant lobsters weigh over 40 pounds and stretch beyond 3 feet long. Their biggest threats? Not old age, but predators or the risky process of shedding their shells. In theory, they could live forever if left alone—but let’s be honest, not many get to enjoy a peaceful, lobster-sized retirement!
