Everybody makes mistakes

“Decimate” doesn’t mean what you think: Words often used incorrectly

Surely, we’ve all made grammatical mistakes that still haunt us. But that doesn’t mean our eyes are safe from twitching when we hear words like "irregardless." A dozen popular mistakes have spread and infiltrated the vocabulary of many, much to the dismay of word lovers. Let’s explore some of these and hope we aren’t among the ones committing them!

Careful: If you say you are nauseous, that means you are causing someone else nausea. You probably don’t mean that you stink, but that you are feeling sick yourself.

When stepping off a rollercoaster, you don’t feel nauseous: You might feel nauseated, which is the correct term.

When did people start using "infamous" interchangeably with "famous"? It’s hard to know, but this mistake is heard often. Remember, "infamous" and "notorious" are adjectives that imply the subject has a bad reputation.

Maybe the confusion comes from "famous" being right there in the word, but keep in mind: infamous isn’t the kind of fame you want.

If you’re bemused, you’re scratching your head, not laughing. "Bemused" gets thrown around as a fancier way to say "amused," but it actually means "confused" or "bewildered." One often isn’t bemused by a funny meme, but a complex set of instructions could leave you bemused.

People often use "decimate" to mean "destroy entirely," but its original meaning is "reduce by one-tenth." It derives from a Roman practice of punishing armies.

For example, you could announce that a crop was decimated by pests but that some survived. The confusion is likely because "one-tenth" doesn’t sound dramatic enough. Ironically, modern misuse has decimated the word’s original meaning.

Some people wrongly state that they have perused a magazine when what they did was flip through it lightly. To "peruse" means to read thoroughly and carefully.

You could peruse a contract document before signing it, for example. Remember, the verb shouldn’t be used as a fancy synonym for "skim."

"Irregardless" gets thrown around, but mostly as the less-preferred form of the word "regardless." Adding "ir-" to it makes it a nonstandard double negative. The word "regard-less" already means "without regard."

Why do people use the wrong form, then? Maybe inventing a prefix feels extra emphatic, but really, it’s like putting a hat on a hat.

"Supposably" is often (and incorrectly) used instead of "supposedly." While the former does exist, it means "as could be imagined or believed". "Supposedly" means "according to what is assumed or believed".

So, which adverb should be used? It depends on whether the reality described is supposed to be true (supposedly) or possible to be true (supposably).

Irony isn’t just a coincidence or bad luck; it’s when there’s a contradiction between expectation and reality. It would be ironic, for example, that a fire station should burn down.

If you simply ran into someone you know, however, that would not be ironic. It would simply be a funny coincidence.

"Literally" means something is true exactly as is stated. It is often misused for exaggerations to add emphasis.

People have grown used to inserting that word into any hyperbolic sentence, such as "I’m literally dying of laughter". The word does have its correct place in some phrases, though. For example, you could literally trip over your own shoelaces.

You cannot feel jealous of someone who enjoys something that you’ve never had. That’s because, strictly speaking, "jealousy" involves the fear of losing something.

"Envy" would be the correct term for referring to the desire to have what someone else does. For example, envying a gold medal when you only achieved the silver one.

Sometimes students claim to be failing a class because they are "disinterested" in the subject, which is an incorrect statement. "Disinterested" means "impartial", or "unbiased". What they mean is that they are not interested, or "uninterested".

"Affect" is a verb, meaning "to influence," while "effect" is a noun, meaning "a result." These two are spotted in the wrong sentence way too often. A speech can have an effect on an audience, but it cannot "effect" the audience. It can only "affect" it.

The space between the words (or lack thereof) does affect the meaning! "Everyday" is an adjective meaning ordinary, while "every day" means "each day." Ask yourself carefully which of the two you are using.

Remember, every day we can find everyday words used incorrectly!

Letters with meaning

Think you know what "PIN" stands for? Let’s test that!

You probably rattle off "PIN," "USB," or "Mrs." without hesitating, but do you actually know what those letters stand for? Some abbreviations come from Latin, some from long-lost measurements, and a few make absolutely no sense at first glance. So let’s dive into the interesting roots of 12 common abbreviations you’ve been using for years.

Why "No." for "number" when there’s no "O" in the word? You can blame Latin on that one.

The abbreviation comes from numero, meaning "number," which was originally abbreviated as an "N" with a small "o" above it (Nº). That old symbol eventually morphed into the familiar No. we still use today.

The abbreviation "lb" actually comes from libra pondo, Latin for "a pound by weight." The pondo gave us the English word "pound," while the libra stuck around as "lb."

It’s also why the British pound symbol (£) looks like a fancy "L." How interesting is that?

"Ounce" and "oz" don’t match up phonetically, but historically, they’re connected. The word comes from the Latin uncia, meaning one-twelfth of a Roman pound.

It passed through Italian as onza, which is how we ended up with the abbreviation oz. Now it makes a little more sense, don’t you think?

Most of us know whether it’s morning or night without translating Latin, right? But there’s some history behind these time markers. A.M. stands for ante meridiem (before noon) and P.M. for post meridiem (after noon).

You’ve probably seen "post" in other words like "post-op" or "postwar"—now you know why it shows up in time too!

"PIN" stands for "personal identification number"— so saying "PIN number" is technically redundant.

Scottish engineer James Goodfellow created the PIN system in 1966 when he patented an early cash machine. Now it’s second nature, and we don’t even think twice about typing it in.

Bonus fact: "ATM" stands for "automated teller machine," so saying "ATM machine" is also a redundancy.

"CC" stands for "carbon copy," from the days when people used carbon paper to make duplicates of typed letters. You’d slip a sheet between two papers, type your note, and you had two copies.

The email version took off in the 1980s, and we’ve been CC-ing ever since.

"BCC"? That’s "blind carbon copy," meaning the recipient is hidden from others. How about that, huh?

"Universal Serial Bus" might sound like a fancy Greyhound line, but it’s actually the system that helps gadgets talk to each other.

In computer terms, a "bus" is a communication channel, like a digital highway. The USB was created in the mid-1990s to simplify connecting devices.

You’ve probably seen "et al." on academic papers or research articles. It’s short for et alia, Latin for "and others."

Only the "al" is abbreviated, which is why it gets the period. The word alia is also the root of "alias," a name used by someone else. But you already knew that one, didn’t you?

CV stands for curriculum vitae, Latin for "course of life." It’s a fancier version of a résumé and is often used in academia or overseas job applications.

The phrase popped up in the early 1900s and adds a bit of sobriety to your work history. Who said job hunting couldn’t be sophisticated?

"MO" stands for modus operandi, Latin for "method of operating." Originally, it described the signature behavior of criminals, but these days it’s more broadly used to mean someone’s usual way of doing things.

If your uncle always steals the last slice of pie, that’s just his MO. Sneaky, but predictable, you know.

The SIM in your phone stands for "Subscriber Identity Module." It’s what tells the network who you are and lets you make calls, send texts, and use data.

First rolled out in 1991, SIM cards act like your phone’s ID badge—without one, your phone’s just a fancy calculator.

"Mrs." looks like it should rhyme with "mars," but we say it "missus." That’s because it originally stood for "mistress." Don’t worry— not the scandalous kind, just the lady of the house.

Over time, mistress took on new meanings, but the "R" stayed behind in the abbreviation. Go figure.
