We all slip up from time to time, but it turns out that some errors are more common than others, especially when it comes to reading and writing. Of course, there is no "unique" way to use language, but even if we've spoken English since childhood, there are still common "mistakes" that native speakers tend to make. Read on to see if you make any of these too!

1

There/their/they're

Ever received a message that reads, "I love they're new house"? Homophones are words that sound the same (or very, very similar), and this is the case with "there," "their," and "they're," which is why many native speakers tend to confuse them.

However, these three words have quite different meanings and functions. "There" can be used with the verb to be, as in "There's a problem with your order," or as an adverb to indicate place: "I found the cat; it's there!" On the other hand, "their" functions as a possessive, indicating ownership, as in "I love their new house." Finally, "they're" is a contraction of "they are," as in "They're a lovely couple."

2

Your/you're

You've probably written or read something like "I think your right about that" or "I'd love to meet you're parents." These usages are considered incorrect, but don't worry—you’re not alone! Like the words in the previous entry, "your" and "you're" are homophones, meaning they sound identical when spoken.

To understand them better, remember that "you're" is a contraction of "you are" (pronoun + verb), as in "You're the best friend I ever had." Meanwhile, "your" is a possessive adjective, which indicates that something belongs to "you."

3

Fewer/less

This case is different from the previous ones. The common confusion between "fewer" and "less" has nothing to do with pronunciation but rather with meaning, as both are quantifiers used for comparisons and indicate a smaller quantity.

The key is knowing which type of noun each word should be used with. "Fewer" is used with countable nouns (things you can count individually), as in "He made fewer mistakes this time." On the other hand, "less" is used with uncountable nouns (things you can't count individually, as they are considered a whole), such as in "You drank less water today than yesterday."

4

Affect/effect

Another case of commonly confused words is "affect" and "effect." In addition to their similar pronunciation, these two terms also have related meanings, making it even more challenging to distinguish between them.

"To affect" is a verb meaning "to cause a change" or "to influence." For example, you can say, "Cold weather affects my mood." On the other hand, "effect" is a noun that indicates the consequence of an action or change, as in "The storm had a devastating effect on the city." To simplify: "affect" is the action, while "effect" is the result.

5

Me/I

Many times, we tend to say things like, "The teacher gave an assignment to Lily and I." While that's quite common, it's actually a grammatical error.

We know it’s difficult to tell them apart: both are pronouns used to refer to oneself. However, each has a different function. "I" is used as the subject of the sentence (the one performing the action), as in "Sarah and I went to the store." "Me," on the other hand, is used as the object of the sentence (the one receiving the action), as in, "The doctor told Lucas and me to drink more water."

6

Lose/loose

Image: Jozsef Hocza

Another pair of very, very similar words: lose and loose. The key to distinguishing them is understanding what kind of word each one is.

"Lose" is a verb, meaning it always indicates an action (and can be expressed in the past, present, or future tense). For example: "I don't want to lose my keys" or "Joan lost the remote control." On the other hand, "loose" is an adjective, meaning it describes the characteristics, state, or condition of something, as in "I prefer loose pants; tight ones make me uncomfortable."

7

Well/good

Image: René Porter

"I slept well last night" or "I slept good last night"? (Spoiler: it's the first one!) But why? While both "well" and "good" are used to describe something positively, they are different types of words.

"Well" is an adverb, meaning it describes the verb. In the sentence "She sings well," the adverb modifies the verb "sings." Meanwhile, "good" is an adjective, so it describes a noun, as in "She's a really good singer!"

8

Could have/Could of

Image: Ben Mullins

The confusion between "could have" and "could of" is so widespread that many of us sometimes don’t even notice it. This error usually occurs because of the way they sound when pronounced.

When said quickly in conversation, "could have" can sound like "could of." But there's only one correct form: "could have" ("could of" has no grammatical meaning). For example, "I could have done better on the test" is correct, while "I could of done better on the test" is not.

9

Lay/lie

Image: Vladislav Muslakov

Ok, homophones really can cause chaos, and this is the case with the words "lay" and "lie," which also have similar meanings. We must warn you: If you say, "I need to lay down," you're officially guilty!

While both words have to do with position, "lay" requires a direct object (something being placed), whereas "lie" does not. In other words, "lay" means to put something down (it needs an object), while "lie" means to recline or rest (no object needed).

10

Literally

Image: Randy Tarampi

Finally, we have a word that has often been used incorrectly or exaggeratedly in recent times: "literally" — or just "lit" if you're really cool.

According to the dictionary, "literally" means something happened exactly as stated, without exaggeration. However, in modern slang, it's often used to emphasize or dramatize a situation. For example, you might hear someone say, "I literally died laughing." Of course, if they're saying it, then luckily, they didn't literally die!


The truth about your brain

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


Published on March 16, 2025

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!

1

Myth: We only use 10% of our brain

Image: Natasha Connell

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!

2

The brain itself can’t feel pain

Image: Aarón Blanco Tejedor

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.

3

Headaches are actually chemical reactions

Image: Usman Yousaf

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.

4

Dreams: Your brain’s midnight movie theater

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.

5

Your short-term memory lasts less than 30 seconds

Image: Brett Jordan

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!

6

Brain freeze is your body’s warning signal

Image: BUDDHI Kumar SHRESTHA

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!

7

Your brain thinks a lot!

Image: Josh Riemer

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.

8

Your brain uses 20% of your body’s oxygen and blood

Image: Terry Vlisidis

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!

Seeing stars? That’s your brain processing vision!

Image: Alexander Andrews

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.

10

Your brain can power a light bulb!

Image: Rodion Kutsaiev

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.

11

Your brain is mostly fat

Image: Robina Weermeijer

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!

12

Your brain shrinks as you age

Image: Robina Weermeijer

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!

13

Cholesterol plays a big role in memory

Image: Lisa Yount

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!
