Looking to sound smarter? Here are 12 redundant words & how to avoid them

Some of these phrases belong to what is known as RAS (Redundant Acronym Syndrome), a linguistic phenomenon in which an acronym or initialism is used alongside one of the words it represents, such as "ATM machine." Others are simply redundancies that have become common through frequent use, like "free gift." Still, we all use a couple of these—at least. Which of these 12 do you use the most?

The phrase "ATM machine" is redundant because "ATM" already stands for "Automated Teller Machine," so adding "machine" repeats the word unnecessarily. It’s like saying "Automated Teller Machine machine."

This phrase is not the only example of RAS on the list, as we will see in the following entries.

An expression commonly found in advertising and marketing, "free gift," is redundant because a gift already means something given without payment. Adding "free" simply repeats what the word "gift" already implies.

Though often used in advertising to emphasize that there’s no cost, "free gift" technically restates the same idea twice.

Saying "PIN number" is redundant because "PIN" already stands for "Personal Identification Number," so adding "number" repeats the word unnecessarily.

While common in casual speech, this expression is best avoided in formal or precise writing.

Another redundant phrase, "end result" falls into this category because "result" already means the outcome of something. Adding "end" repeats an idea that’s already implied in the word.

Saying "end result" is like saying "final outcome outcome." Simply using "result" is clear and complete on its own. Though stylistically the phrase is still widely used for emphasis in both spoken and written English.

"Added bonus" is redundant because a bonus already means something extra or beyond what’s expected. Saying "added" simply repeats the idea unnecessarily. Since "bonus" already implies an addition, the word "added" doesn’t contribute any new meaning. It’s a clear example of redundancy in language.

Like "free gift," this phrase is very common and often used for emphasis in everyday speech or marketing.

"Close proximity" is redundant because "proximity" already means closeness or nearness. Adding "close" simply repeats the same idea.

Not unlike the previously mentioned "PIN number," where "number" is already part of the acronym. In both cases, one word unnecessarily duplicates the meaning of the other.

The expression "advance warning" is redundant because a warning already implies something given ahead of time. Adding "advance" simply repeats the idea of "beforehand."

Since "warning" means prior notice of danger or trouble, saying "advance warning" is like saying "beforehand warning," which adds no new meaning. However, it’s worth noting that this phrase is very common and often considered idiomatic, especially in formal or technical contexts.

This one should be obvious, but we’ve all seen it from time to time. "Unexpected surprise" is redundant because a surprise is, by nature, not expected.

Saying "unexpected" adds no new meaning—unless, of course, the person was already expecting a surprise and received a different one, which effectively surprised them.

Saying that something is "completely destroyed" is redundant because "destroyed" already means total ruin. Adding "completely" simply repeats the idea without adding any new meaning.

When something is destroyed, it’s already beyond repair or use. Saying "destroyed" alone is clear and sufficient.

A much-used phrase in the age of fake news, "true fact" is redundant because a fact is, by definition, something that is true or can be proven. Adding "true" just repeats what’s already implied.

It’s like saying "frozen ice" or "past history"—the second word adds no new meaning. While "true fact" may be used for emphasis, it’s unnecessary and best avoided in formal writing.

Since all plans are, by nature, in the future, the expression "future plans" is redundant. Adding "future" repeats what is already understood.

Unless you have a time machine, you can’t make plans for the past, so the word "future" adds nothing. Simply saying "plans" is clear and more concise.

Another expression used for added drama, "unsolved mystery" is redundant because a mystery already implies something unexplained or unresolved. Adding "unsolved" repeats what’s inherently part of the word.

A mystery is, by definition, something not yet understood, so saying "mystery" alone is clear and more concise.

Codewords decoded: How many did you know?

In situations where clear communication is paramount, especially when lives are at stake, professionals often rely on standardized codewords and phonetic alphabets designed to prevent confusion. Either from movies or from personal experience, it's probable that you've heard at least some of these before, and many have found their way into everyday conversation. Let's find out how many of these code expressions you can recognize.

Mayday is the international distress call used when the sender is in immediate, life-threatening danger. Pilots and mariners use it to signal that they require urgent assistance due to situations such as engine failure, fire, flooding, or medical emergencies.

The word was introduced in 1923 by British radio officer Frederick Stanley Mockford, who based it on the French phrase m'aider, meaning "help me," in an attempt to make it internationally recognizable. Hearing this transmission immediately alerts emergency responders that every second counts.

Not every emergency is severe enough to warrant a mayday call. When a crew faces a problem that is urgent but not immediately life-threatening, the appropriate codeword is Pan-Pan.

Like mayday, it comes from French: it derives from panne, meaning a breakdown or mechanical failure. A Pan-Pan call might be used if an aircraft loses an engine but can still fly safely, or if a ship experiences equipment problems while remaining under control. It tells responders that assistance is needed, but that the situation has not yet become critical.

Few emergency signals are as universally recognizable as SOS. Contrary to popular belief, the letters do not officially stand for "Save Our Ship" or "Save Our Souls." It was adopted in 1906 because SOS is an extremely simple, easy-to-transmit, and unmistakable pattern in Morse code.

SOS remains one of the world's most enduring distress signals, and it's still recognized by rescue organizations all around the globe.

In the NATO phonetic alphabet, each letter is assigned a unique word to eliminate confusion when radio transmissions are distorted by noise or poor reception. If you've ever heard someone spell a name as "Mike Alpha Romeo Yankee," you've encountered the NATO phonetic alphabet.

The system was officially adopted by NATO in the 1950s and is now widely used by militaries, airlines, emergency responders, and many police departments worldwide. Using it greatly reduces the chance of misunderstanding important information over radio.

Roger dates back to the early days of radio communication, when the letter R stood for "received." Before the adoption of the NATO alphabet, the US military used Roger instead of Romeo to represent that letter_._

Although modern communications systems have changed and the US military has fully embraced the use of the NATO alphabet, Roger remains standard aviation terminology, and it's one of the best-known radio acknowledgments in the world. It conveys a very simple but important meaning: "I have received and understood your message."

Although many people assume Roger and Wilco mean the same thing, they actually convey different messages. Wilco is short for "will comply." In other words, it tells the sender not only that the message was received and understood, but that the instruction will be carried out.

Saying both Roger and Wilco is technically redundant in proper radio communication, since complying necessarily implies understanding, but the combination is often heard in movies and television.

In the NATO phonetic alphabet, Tango simply represents the letter T. However, US military personnel have also adopted it as a shorthand when referring to a target or a hostile.

This secondary meaning became widely known through military operations in the twentieth century and has since appeared in countless books, films, and video games in phrases like "We've got one Tango moving north."

Oscar Mike, NATO for the letters O and M, is military shorthand for "On the Move." It's a quick way of reporting that a unit has begun moving toward its objective.

The expression is especially common in the US military and has become more familiar to the general public through documentaries, memoirs, and films. It's finding its way into civilian life, meaning simply "I'm heading out."

Ten-codes were developed during the 1930s to allow for brevity and standardization of message traffic in radio communications. They were widely adopted by US public safety departments and by radio enthusiasts.

While the system is being slowly phased out in favor of plain language communications, many local police, fire, and sheriff departments keep using it, and it is still strongly associated with radio culture by the general public. One of the most famous ten-codes is 10-4, meaning "received and understood."

Hospitals around the world use color-coded announcements to communicate emergencies without causing unnecessary panic among patients and visitors. Perhaps the best known is Code Blue, indicating that a patient is experiencing cardiac or respiratory arrest and requires immediate medical assistance.

While some hospitals use their own custom color codes, Code Blue has become so widely recognized that it now appears frequently in television dramas and everyday conversation whenever someone refers to a life-threatening medical emergency.
