Can you say this 85-letter word? English’s extreme mouthfuls

In casual conversation, you’d probably never use most English words that go past 15 or 20 letters. They are usually scientific or medical terms built by stacking smaller words together. Yet, exploring these linguistic giants is a fun way to learn how our language handles specialized vocabulary. Let’s take a look at some of the longest words in the English-speaking world, starting with one so ridiculously big it stretches the definition of what a word can be. Can you guess what it is?

To kick off the list, we have to look at a number that looks like a typo, but is entirely accurate: 189,819 letters. This is the full chemical name for the human muscle protein known commonly as titin.

Because proteins are complex chains of amino acids, their formal chemical names must list every single component in order. This particular sequence starts with methionylthreonylthreonylglutaminylarginyl… and keeps going for thousands of syllables. If you wanted to print it out, it would easily fill more than 50 pages. Want to try reading it out loud? You might want to clear your schedule, because it would take more than three hours.

The longest place name in English belongs to a 1,001-foot-high hill located in Hawke's Bay, New Zealand. It boasts a staggering 85 letters: Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu.

Derived from the Māori language, this long title translates to a poetic statement: "the place where Tamatea, the man who had big knees, the climber of mountains, the slider, the land-swallower that traveled about, played the nose flute that he had to the loved ones". Unsurprisingly, locals and tourists alike usually save their breath and refer to it simply as "Taumata".

Not to be outdone, the United States has its own geographical giant sitting in Massachusetts. With a total of 49 letters, Lake Chargoggagoggmanchauggauggagoggchaubunagungamaugg is the longest official place name in America.

While the name originates from the language of the Nipmuc people, this huge version is believed to be a humorous invention by a local newspaper editor in the early 20th century. Along with the long spelling, the editor popularized a fake translation: "You fish on your side; I fish on my side; nobody fishes in the middle." Today, it’s also known as Webster Lake by anyone trying to type it into a GPS.

The longest word entered in most standard English dictionaries is Pneumonoultramicroscopicsilicovolcanoconiosis, which is 45 characters long. Found in specialized volumes like Merriam-Webster’s Medical Dictionary, it refers to a severe lung disease caused by the chronic inhalation of fine silicate or quartz dust, typically associated with volcanic activity. Ironically, medical professionals don’t actually use this word in daily practice; they simply call the condition silicosis.

Pseudopseudohypoparathyroidism, at 30 letters, is a rare medical condition that mimics the physical skeletal traits of another disorder called pseudohypoparathyroidism. Aside from its impressive physical length, it holds a unique distinction in lexicography: it’s the only word in the dictionary that features a repeating consecutive "pseudo".

There’s a unique category of words that almost never appear in real sentences. Because they lack everyday utility, dictionaries acknowledge their existence but choose not to give them formal entries.

This group includes antidisestablishmentarianism (28 letters), which refers to a 19th-century political movement in Britain. Also, the classic floccinaucinihilipilification (29 letters), a mashup of Latin roots that means the act or habit of judging something to be completely worthless. Finally, the most beloved of this group is supercalifragilisticexpialidocious (34 letters), the iconic nonsense phrase made famous by Walt Disney’s Mary Poppins.

In the medical world, knowing a term like methylenedioxymethamphetamine (29 letters) is essential. While that mouthful might look unfamiliar at first glance, it refers to a synthetic amphetamine known for its hallucinogenic properties. Because nobody wants to write or say all 29 letters in a casual conversation, people have opted to use its much shorter street name, ecstasy, or its concise chemical acronym, MDMA.

In the context of a research lab, some specialized technical terms fall into the twenty-to-thirty-letter sweet spot. Some of them are: Electroencephalographically (doing something by means of an electroencephalograph, a medical machine used to read and record brain wave patterns); radioimmunoelectrophoresis (a laboratory technique that uses radioactive labels to analyze specific proteins); laryngotracheobronchitis (a medical condition involving severe inflammation in the larynx, trachea, and bronchial tubes); and hydrochlorofluorocarbon (a type of greenhouse gas).

These are long but feel more recognizable. At 22 letters, we can find terms like counterrevolutionaries (individuals who fight to overthrow a newly established revolutionary government), deinstitutionalization (the social and political process of moving patients out of asylum institutions), and otorhinolaryngological (anything relating to the medical specialty of the ear, nose, and throat).

If you’re looking for everyday 21-letter words, terms like incomprehensibilities (things that are impossible to understand) will do the trick. Also, this tier features medical terms like pseudohermaphroditism (a condition involving ambiguous external genitalia) and psychoneuroimmunology (the branch of medicine that studies how a person’s emotional state impacts their immune system).

The truth about your brain

You won’t believe what happens in your brain while you sleep

Your brain is one of the most powerful and mysterious organs in your body. It controls everything from your thoughts to your emotions and even processes information at lightning speed. But how much do you really know about it? Some long-believed myths about the brain have been debunked, while other surprising facts reveal just how incredible this organ truly is. Get ready to be amazed by these fascinating brain facts!

You’ve probably heard this one before, but it’s completely false! While it’s true that not all parts of the brain fire at the same time, imaging studies show that most regions are active throughout the day, even when we sleep.

Your brain is constantly working, controlling bodily functions and emotions, and processing information. So next time someone says you’re only using 10% of your brain, you can confidently tell them that’s just a myth!

Here’s a weird fact: While your brain processes pain signals from the rest of your body, it has no pain receptors of its own. This is why surgeons can perform brain surgery on conscious patients without causing them pain.

However, the membranes and tissues surrounding the brain do have pain receptors, which is why headaches and brain injuries can be so excruciating.

How come we have headaches if the brain has no pain receptors? Well, that’s because headaches are triggered by chemical activity in the brain, changes in nerves and blood vessels, and even fluctuating serotonin levels.

In some cases, hormones like estrogen can also play a role, which explains why migraines are more common in women.

Dreams are proof that your brain never rests! (Warning: this fact can make you feel exhausted.) While you sleep, your limbic system, that is, the part of the brain that deals with emotions, becomes especially active, which is why dreams often feel so intense.

On average, humans experience four to seven dreams per night, even if we don’t always remember them. And what about that scary nightmare about falling? Well, you can thank your amygdala, the brain’s fear center, for that one.

Have you ever walked into a room and instantly forgotten what you were after? That’s because short-term memory only lasts about 20-30 seconds! That’s not enough!

Your brain holds a limited amount of information in its active state before deciding whether to store it or discard it. Ironically, we can’t really choose what makes the cut, but we do hope these facts stay with you!

That sharp, icy pain when you eat something too cold? It’s your brain’s way of telling you to slow down! Officially called sphenopalatine ganglioneuralgia, a brain freeze happens when cold food or drinks rapidly chill the blood vessels in your throat, causing them to constrict and then rapidly expand. This sends pain signals to your brain, warning you of the sudden temperature shift. It’s annoying, but it’s actually your body trying to protect itself!

You didn’t need us to tell you, but let’s look at the details: The average person has between 12,000 and 60,000 thoughts per day. What’s even more interesting? 95% of those thoughts are the same ones you had yesterday. Is that not surprising enough? Hear this out: 80% of them tend to be negative. That’s because our brains are wired for survival, constantly analyzing risks and potential dangers.

Even though it only makes up about 2% of your body weight, your brain employs a major quantity of energy! It consumes 20% of your oxygen and blood supply, making it one of the most demanding organs in your body.

If your brain goes without oxygen for just five minutes, brain cells start dying, leading to irreversible damage. This is why deep breathing and cardiovascular exercise are great for brain health!

Do you know that feeling when you hit the back of your head and see stars? That’s because your occipital lobe, which controls vision, is located at the back of your brain. If you get hit there, your brain momentarily misfires, causing flashes of light.

Interestingly, your brain processes vision on the opposite side; while your right brain controls your left eye, your left brain controls your right eye. It’s one of the many ways the brain operates in a complex way.

Believe it or not, your brain generates between 12 and 25 watts of electricity when you’re awake. If you can’t really grasp how powerful that is, check this out: It’s enough to power a small light bulb! Your brain’s electrical activity is what allows neurons to send signals at speeds of up to 260 miles per hour.

Your brain may be the fattiest organ in your body, consisting of at least 60% fat! This is why consuming healthy fats, like omega-3s and omega-6s present in fish, for example, is essential for brain health.

Healthy fats stabilize brain cell walls, reduce inflammation, and support cognitive function. So go ahead and enjoy that avocado toast, it’s food for your brain!

It’s not just your memory that fades over time; the brain itself physically shrinks as one gets older. It continues developing until your late 40s, but after that, it slowly decreases in size.

Now, size doesn’t equal intelligence, so a smaller brain doesn’t necessarily mean a less capable one. Staying mentally active, exercising, and eating brain-boosting foods can help keep it in top shape!

We often think of cholesterol as bad, but your brain actually depends on it! In fact, 25% of your body’s cholesterol is stored in your brain, where it helps with learning and memory. However, unlike other organs, the brain can’t absorb cholesterol from the blood, it has to produce its own. So, while too much cholesterol in the body can be harmful, the right amount is vital for brain function. At least you can use that as an excuse to get that burger!
