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.

Who doesn't like a good mystery? And if the mystery isn’t a work of fiction but the result of a true story, even better! The great unsolved enigmas of history are absolutely fascinating. Some have been solved over time, but there are still many old secrets for which neither scientists nor historians have found an explanation—yet. Time-travel with us as we uncover 10 of the biggest historical mysteries that will probably never be cracked!

Bermeja Island is mentioned in navigation texts written by European travelers and appears in cartography from the 16th to 19th centuries. Old maps place it off the north coast of the Yucatán Peninsula; however, multiple searches over the years have yielded no concrete evidence of its existence.

So, what happened to Isla Bermeja? Was it a cartographic error? Did it sink due to a tidal wave? Because of its geopolitical significance, some have even suggested that it was blown up by the CIA! A 2009 study by the Autonomous University of Mexico concluded that Isla Bermeja does not exist today, nor were any traces found at its supposed coordinates. Yet, it will forever remain a mystery that will surely keep many entertained.

In 1977, Ohio State University’s Big Ear radio telescope, used in the search for extraterrestrial intelligence, detected a signal now known as the Wow! signal. While reviewing the data, astronomer Jerry R. Ehman noticed a sequence represented as "6EQUJ5." Baffled by the anomaly, he circled it and wrote "Wow!" in the margins.

The signal lasted 72 seconds and, unfortunately, has never been repeated. To this day, no one can fully explain the phenomenon, although some suggest it may have come from a man-made source. Still, the Wow! signal remains one of the strongest candidates for potential extraterrestrial contact ever detected.

How is it possible for an entire village to vanish without a trace? Believe it or not, this is said to have happened nearly a century ago. According to lore, a small Inuit village in Canada was well known among fur trappers who visited regularly to trade. But in 1930, something very strange supposedly occurred.

A hunter named Joe Labelle claimed he visited the village one day and couldn’t find a single person. Reports said there were guns and food left behind, and even claims that the graves in the cemetery were empty. A thorough investigation, however, found no conclusive evidence of what happened to the villagers. Some witnesses from nearby towns even reported seeing a huge green light. Theories ranged from mass migration to extraterrestrial abductions. The Royal Canadian Mounted Police has since dismissed the case as an urban legend. Some still believe the story to be true.

We know thousands of shipwreck stories, but this one is quite unique. The MV Joyita, designed to be nearly unsinkable, was found adrift in the South Pacific, practically unharmed, but the crew had disappeared completely.

In October 1955, the American merchant vessel left the port of Apia in Samoa with 16 crew members and 9 passengers bound for the Tokelau Islands. After days without news, a rescue mission was launched. Five weeks later, the Joyita was spotted more than 600 miles west of its intended route. The vessel was partially submerged, and there was no sign of the passengers or crew. Four tons of cargo and all three life rafts were missing. They were never seen again.

Do you know where one of the best-preserved mummies was found? Hint: not in Egypt. Xin Zhui, the Marquise of Dai during the Western Han Dynasty in China, was discovered in her tomb at Mawangdui 2,000 years after her death, along with hundreds of valuable documents and artifacts.

What makes this mummy so extraordinary is how well-preserved her body is. Her organs and veins remain intact, and she still has hair and even eyelashes. Scientists analyzed the fluid present in the coffin and discovered it was acidic and contained salt and magnesium. They believe this mysterious liquid may have been responsible for preserving Xin Zhui so well. What they don’t know is whether it was intentionally poured into the coffin or came from the body itself.

The United States has its fair share of presidents who died while in office, but none of our 45 presidents have ever disappeared without a trace. Did you know that this actually happened in The Land Down Under?

Harold Edward Holt was the Prime Minister of Australia from 1966 until his presumed death in 1967. He loved the ocean and spearfishing. During a weekend trip with friends, Holt visited the remote Cheviot Beach to take a swim. Rough sea conditions that day caused him to be swept away by the waves, and he never reappeared. Despite an intensive search, his body was never found, which has given rise to numerous conspiracy theories. Ironically, Australians built the Harold Holt Memorial Swimming Centre in Melbourne in his honor.

Many famous criminals have managed to remain unidentified for decades, but the D.B. Cooper case is something else entirely. In 1971, Cooper boarded a flight from Portland to Seattle. Shortly after takeoff, he showed a flight attendant a device he claimed was a bomb and demanded four parachutes and $200,000 in cash.

The crew landed to meet Cooper’s demands in exchange for the passengers and then took off again. As the plane flew over southwestern Washington, Cooper jumped into the cold, rainy night carrying his haul. His whereabouts and true identity were never discovered, although it is likely he didn’t survive the jump. In 1980, some of the ransom money was found near the Columbia River. Although the FBI officially closed the case in 2016, amateur sleuths continue to try to crack it.

Can you imagine an epidemic where the main symptom is uncontrollable dancing? Sounds like science fiction, doesn’t it? Yet this really happened during the Middle Ages. In 1518, a dancing plague struck Strasbourg, Alsace, in what is now France. This strange condition affected up to 400 people, making them dance frantically for weeks. It is said that some even died of heart attacks, exhaustion, or strokes.

Doctors and authorities tried all kinds of measures to stop the spread. They even banned music for a while! To this day, scientists are not certain what caused this bizarre condition: it may have been food poisoning from toxins in the ergot fungus, or perhaps a case of stress-induced mass hysteria.

The Voynich manuscript is a codex written roughly 500 years ago in an unknown language and writing system by an anonymous author. Known as Voynichese, the manuscript was named after Wilfrid Voynich, a Polish bibliophile and antiquarian who purchased it in 1912.

Radiocarbon testing has shown that it dates to the early 15th century. Many cryptographers and codebreakers have attempted to decipher its roughly 240 pages without success. The manuscript contains diagrams and illustrations of unknown plants and astrological symbols. Some believe it may be a made-up language, a secret code, a work of fiction, or even a hoax. If you think you can solve this mystery, the Voynich manuscript is available for viewing at Yale University’s Beinecke Rare Book and Manuscript Library.

Similar to the Voynich manuscript, the Phaistos Disc is a fired clay disc believed to have been created during the Bronze Age. It was discovered by an Italian archaeologist in the basement of a palace in Crete, Greece, in 1908.

What makes this disc fascinating is that it contains a mysterious message. Stamped into the clay is a set of signs, forming a text that many scientists have tried to decipher—without success. It is considered an early attempt at printing, a technological innovation that would not become widespread for several centuries. While enthusiasts still hope the enigma can be solved, this is unlikely unless other documents are discovered to provide context.
