25 Words That Are Their Own Opposites

Here’s an ambiguous sentence for you: “Because of the agency’s oversight, the corporation’s behavior was sanctioned.” Does that mean, "Because the agency oversaw the company’s behavior, they imposed a penalty for some transgression," or does it mean, "Because the agency was inattentive, they overlooked the misbehavior and gave it their approval by default"? We’ve stumbled into the looking-glass world of contronyms—words that are their own antonyms.

1. Sanction (via French, from Latin sanctio(n-), from sancire ‘ratify,’) can mean "give official permission or approval for (an action)" or conversely, "impose a penalty on."

2. Oversight is the noun form of two verbs with contrary meanings, “oversee” and “overlook.” Oversee, from Old English ofersēon ("look at from above") means "supervise" (medieval Latin for the same thing: super-, "over" plus videre, "to see.") Overlook usually means the opposite: "to fail to see or observe; to pass over without noticing; to disregard, ignore."

3. Left can mean either remaining or departed. If the gentlemen have withdrawn to the drawing room for after-dinner cigars, who’s left? (The gentlemen have left and the ladies are left.)

4. Dust, along with the next two words, is a noun turned into a verb meaning either to add or to remove the thing in question. Only the context will tell you which it is. When you dust are you applying dust or removing it? It depends whether you’re dusting the crops or the furniture.

5. Seed can also go either way. If you seed the lawn you add seeds, but if you seed a tomato you remove them.

6. Stone is another verb to use with caution. You can stone some peaches, but please don’t stone your neighbor (even if he says he likes to get stoned).

7. Trim as a verb predates the noun, but it can also mean either adding or taking away. Arising from an Old English word meaning "to make firm or strong; to settle, arrange," trim came to mean "to prepare, make ready." Depending on who or what was being readied, it could mean either of two contradictory things: "to decorate something with ribbons, laces, or the like to give it a finished appearance" or "to cut off the outgrowths or irregularities of." And the context doesn’t always make it clear. If you’re trimming the tree are you using tinsel or a chain saw?

8. Cleave can be cleaved into two homographs, words with different origins that end up spelled the same. Cleave, meaning "to cling to or adhere," comes from an Old English word that took the forms cleofian, clifian, or clīfan. Cleave, with the contrary meaning "to split or sever (something)"—as you might do with a cleaver—comes from a different Old English word, clēofan. The past participle has taken various forms: cloven, which survives in the phrase “cloven hoof,” “cleft,” as in a “cleft palate” or “cleaved.”

9. Resign works as a contronym in writing. This time we have homographs, but not homophones. Resign, meaning "to quit," is spelled the same as resign, meaning "to sign up again," but it’s pronounced differently.

10. Fast can mean "moving rapidly," as in running fast, or "fixed, unmoving," as in holding fast. If colors are fast they will not run. The meaning "firm, steadfast" came first; the adverb took on the sense "strongly, vigorously," which evolved into "quickly," a meaning that spread to the adjective.

11. Off means "deactivated," as in to turn off, but also "activated," as in the alarm went off.

12. Weather can mean "to withstand or come safely through" (as in the company weathered the recession) or it can mean "to be worn away" (the rock was weathered).

13. Screen can mean to show (a movie) or to hide (an unsightly view).

14. Help means "assist," unless you can’t help doing something, when it means "prevent."

15. Clip can mean "to bind together" or "to separate." You clip sheets of paper to together or separate part of a page by clipping something out. Clip is a pair of homographs, words with different origins spelled the same. Old English clyppan, which means "to clasp with the arms, embrace, hug," led to our current meaning, "to hold together with a clasp." The other clip, "to cut or snip (a part) away," is from Old Norse klippa, which may come from the sound of a shears.

16. Continue usually means to persist in doing something, but as a legal term it means stop a proceeding temporarily.

17. Fight with can be interpreted three ways. “He fought with his mother-in-law” could mean "They argued," "They served together in the war," or "He used the old battle-ax as a weapon." (Thanks to linguistics professor Robert Hertz for this idea.)

18. Flog, meaning "to punish by caning or whipping," shows up in school slang of the 17th century, but now it can have the contrary meaning, "to promote persistently," as in “flogging a new book.” Perhaps that meaning arose from the sense "to urge (a horse, etc.) forward by whipping," which grew out of the earliest meaning.

19. Go means "to proceed," but also "give out or fail," i.e., “This car could really go until it started to go.”

20. Hold up can mean "to support" or "to hinder": “What a friend! When I’m struggling to get on my feet, he’s always there to hold me up.”

21. Out can mean "visible" or "invisible." For example, “It’s a good thing the full moon was out when the lights went out.”

22. Out of means "outside" or "inside": “I hardly get out of the house because I work out of my home.”

23. B**ch can derisively refer to a woman who is considered overly aggressive or domineering, or it can refer to someone passive or submissive.

24. Peer is a person of equal status (as in a jury of one’s peers), but some peers are more equal than others, like the members of the peerage, the British or Irish nobility.

25. Toss out could be either "to suggest" or "to discard": “I decided to toss out the idea.”

The contronym (also spelled “contranym”) goes by many names, including auto-antonym, antagonym, enantiodrome, self-antonym, antilogy and Janus word (from the Roman god of beginnings and endings, often depicted with two faces looking in opposite directions). Can’t get enough of them? The folks at Daily Writing Tips have rounded up even more.

14 Facts About International Talk Like A Pirate Day

Ahoy, me hearties! As many of you know, September 19 is International Talk Like A Pirate Day, an annual phenomenon that’s taken the world by storm, having been observed by every continent, the International Space Station, and even the Oval Office since it first made headlines back in 2002. So let’s hoist the Jolly Roger, break out the rum, and take a look back at the holiday’s timber-shivering history.

1. Talk Like a Pirate Day was originally conceived of on D-Day.

Talk Like a Pirate Day creators John Baur and Mark Summer (who’ve since acquired the nicknames “Ol’ Chumbucket” and “Cap’n Slappy,” respectively) created the holiday while playing racquetball on June 6, 1995—the 51st anniversary of the invasion of Normandy. Out of respect to the battle’s veterans, a new observance date was quickly sought.

2. September 19th also happens to be the birthday of the ex-wife of the holiday's co-creator.

“[September 19th was] the only date we could readily recall that wasn’t already taken up with Christmas or the Super Bowl or something,” the pair later claimed. Summers claims to harbor no ill will toward his former spouse, who has since stated, “I’ve never been prouder to be his ex-wife!

3. Pulitzer Prize-winning humorist Dave Barry is largely responsible for popularizing the holiday.

Dave Barry was so smitten with the holiday after having been introduced to it via email in early 2002 that he dedicated an entire column to its publicity that September, turning an inside joke into a global sensation. He later went on to make a cameo appearance in one of Baur and Summers’s buccaneer-themed music videos in 2011 (look for him in the video above at the 3:25 mark).

4. Real pirates spoke in a wide variety of dialects.

Despite some extensive “English-to-Pirate” dictionaries that have cropped up all over the Internet the idea that all pirates shared a common accent regardless of national origin is historically absurd, as National Geographic pointed out in 2011.

5. Actor Robert Newton is hailed as the "patron saint" of Talk Like a Pirate Day.

So where did the modern “pirate dialect” come from? Summers and Baur credit actor Robert Newton's performance in Treasure Island (1950) and have accordingly dubbed him the “patron saint” of their holiday. Tasked with breathing life into the scheming buccaneer, Newton simply exaggerated his native West Country accent and the rest is history.

6. John Baur's family was featured on a pirate-themed episode of Wife Swap.

The reality show’s highly-anticipated 2006 season premiere pitted the Baurs (in full pillaging regalia) against a family which, according to John’s wife Tori (a.k.a. “Mad Sally”), “behaved as though ‘fun’ was something that had to be pre-packaged for their protection.”

7. John Baur was also on Jeopardy!

Baur was described to the audience as “a writer and pirate from Oregon” in his 2008 appearance. “I didn’t win,” Baur said, “but the introduction made Alex blink.”

8. International Talk Like a Pirate Day has become a cornerstone of the Pastafarian movement.

Bobby Henderson, founder of the Church of the Flying Spaghetti Monster, cited Earth’s dwindling pirate population as the clear source of global warming in his 2005 open letter to the Kansas school board which established the religion. Since then, Talk Like A Pirate Day has been observed by devout Pastafarians worldwide. 

9. A Florida mayor once ignited a local controversy for making an official Talk Like a Pirate Day proclamation.

In 2012, Lake Worth, Florida Mayor Pam Triolo lightheartedly urged her constituents to embrace the holiday last year, writing, “The City … is known to possess a spirit of independence, high spirits, and swashbuckling, all traits of a good pirate.” Her actions were criticized by the city’s former commissioner, Jo-Ann Golden, who took offense to the association with murderous seamen.

10. Day of the Ninja was created in response to Talk Like a Pirate Day.

Not to be outdone by their hated rivals, the pro-ninja community was quick to execute the first annual Day of the Ninja on December 5, 2002. For Summers and Baur’s take on the warring factions, see the clip above.

11. Astronauts once celebrated Talk Like a Pirate Day aboard the International Space Station.

In a 2012 interview, Summers recalled being “informed that the astronauts on the International Space Station were awakened to ‘A Pirate’s Life For Me' and joined in the pirate talk from space.”

12. President Obama once celebrated with a costumed buccaneer in the Oval Office.

In 2012, Barack Obama tweeted this image on Talk Like a Pirate Day with the caption “Arr you in?”

13. A congressman later used the holiday to slam President Obama's tax plan.

In 2011, Florida’s 12th congressional district representative Dennis Ross used the festivity as a political punchline after Obama made a speech detailing his tax plan, tweeting, “It is TALK like a pirate day … not ACT like one. Watch ye purses and bury yr loot, the taxman cometh.”

14. It's an official holiday in the state of Michigan.

On June 4, 2013, state senator Roger Kahn’s proposal to grant International Talk Like A Pirate Day official acknowledgement from the Michigan government was formally adopted, to the chagrin of some dissenting landlubbers.
