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!

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

Treasured guest

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Code Adam

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

Code Blue

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Dr. Firestone

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

Code 10

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

Code Bravo

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

7

Code Alpha

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

10-33

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Signal 70

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Echo, Echo, Echo

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
