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."

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

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!


Facts you didn't know you needed

Is the day longer for your pet? Mind-blowing facts you need to know

Adults often assume they already understand the world, but there’s always something new to surprise us! Did you know that clouds actually have weight? Or that the day is longer for some animals? And that’s just the beginning. From hidden functions of your organs to the true color of the universe, today you’ll learn 10 fascinating facts you probably never thought to ask, but will make you sound impressively smart in your next conversation!

1

Slower time

Unlike humans, animals don’t experience a shared "present" in quite the same way. Instead, their sense of time is tied to the rhythms of their own bodies. For very small animals with fast metabolisms like parrots, hamsters, or guinea pigs, time actually seems to pass more slowly. In a sense, they live in slow motion because their faster-working nervous systems allow them to process sensory information at a fast speed.

Identical twins, but…

What if someone commits a crime and tries to blame their identical twin? Have you ever wondered about that? It’s a valid question; after all, identical twins not only look alike, they also share the same DNA. But here’s the surprising part: if investigators check fingerprints, the innocent twin could be cleared. That’s because, despite their nearly identical DNA, twins have unique fingerprints, shaped by subtle genetic and environmental factors in the womb.

3

Heavy clouds

You’ve probably spent time lying on the grass, watching clouds drift across the sky. They look light, fluffy, almost like cotton candy, and it’s hard to imagine them as heavy objects. But the truth is surprising: clouds are incredibly heavy. An average cumulus cloud can weigh around 1 million pounds! That impressive weight comes from the billions of tiny water droplets suspended in the air. So, how do they float? It’s because each droplet is extremely small and falls very slowly, while rising warm air currents help keep the cloud suspended above us.

Don’t believe everything you see

Most of us have a rough image of the world map in our minds. But we have something to tell you: most maps aren’t completely accurate. Because the Earth is a sphere, cartographers have to distort some areas to represent it on a flat surface. On Mercator projection maps, countries near the poles appear much larger than they really are, while countries near the equator look smaller in comparison. For example, Alaska looks about the same size as Brazil, but in reality, Brazil is nearly five times larger!

5

The Universe's color

Most people don’t realize that there’s actually a name for the color of the universe. Strange, right? But it’s true! Astronomers who studied the light from thousands of galaxies discovered that if you blend all the colors from the observable universe, the result is a soft, beige-ish white shade, famously named "Cosmic Latte" in 2002.

6

No Qs

With 50 states, there’s no shortage of variety in their names. Almost every letter of the English alphabet appears at least once, except for one: Q, which is completely absent. In addition to this, there’s another surprisingly rare letter: J. While it isn’t entirely missing like Q, it only appears in one state, New Jersey.

7

Earth’s rotation is slowing

Image: Carl Wang

Although we don’t notice it, indeed, the Earth’s rotation is gradually slowing. This happens because tidal friction, caused by the Moon’s gravitational pull on our oceans, creates a subtle drag on the planet’s spin. As a result, days are getting longer, but very gradually: by only about 1.7 milliseconds per century.

8

Dreams in sign language

Do you remember your last dream? Whether good or bad, dreams are a constant part of sleep, but not everyone experiences them in the same way. Deaf people who use sign language in their daily lives often communicate through signs in their dreams, too. Meanwhile, blind people tend to have dreams rich in sounds, smells, and tactile sensations, using these other senses to experience the dream world.

9

Walking underwater

Image: Wade Lambert

We’re used to seeing hippos covered in mud, splashing in water, or barely peeking above the surface. But here’s a surprise: hippos can’t actually swim! That’s right. Because of their huge, heavy bodies, they don’t float or paddle like most animals. Instead, they walk or run along the riverbed.

10

Is your brain hungry?

Image: BUDDHI Kumar SHRESTHA

Can your brain really "eat" itself? Well, close, but not exactly. There’s a process called phagocytosis, carried out by specialized immune cells in the brain known as microglia. These cells engulf and remove debris, dead cells, and other unwanted material. But don’t worry; it’s safe! The mechanisms exist to protect, repair, and maintain your brain.
