40 Words and Phrases 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.
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). Here are a few of them.
Sanction—which came to English via French, from Latin sanctio(n-) and sancire, “to ratify,”—can mean “give official permission or approval for (an action)” or conversely, “impose a penalty on.”
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,” according to the Oxford English Dictionary.
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 If the gentlemen have withdrawn to the drawing room for after-dinner cigars, who’s left?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.)
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.
Seed can also go either way. If you seed the lawn you add seeds, but if you seed a tomato you remove them.
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).
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,” according to the OED, trim came to mean “to prepare, make ready.” Depending on whom 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?
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.”
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.
Off means “deactivated,” as in to turn off, but also “activated,” as in the alarm went off.
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).
Screen can mean “to show” (a movie) or “to hide” (an unsightly view).
Help means “assist,” unless you can’t help doing something, when it means “prevent.”
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.
Continue usually means “to persist in doing something,” but as a legal term it means “to stop a proceeding temporarily.”
16. Fight With
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.)
Flog, meaning “to punish by caning or whipping,” showed 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.
Go means “to proceed,” but also “give out or fail,” i.e., “This car could really go until it started to go.”

The uproar was literally earth-shattering in 2013 when the editors of the Merriam-Webster Dictionary announced that literally could mean its opposite: figuratively. Well, remember: Dictionaries don’t legislate what words should mean; they just describe how speakers of a language use them. And, as the Oxford English Dictionary notes, literally has been used colloquially to mean figuratively for literally eons. As Frances Brooke wrote in 1769: “He is a fortunate man to be introduced to such a party of fine women at his arrival; it is literally to feed among the lilies.”
It’s not really an apology unless you say you’re sorry for something you did, right? But what if you’re not the least bit sorry and you make a reasoned defense of your actions or anything else you feel is misunderstood or unappreciated, like Philip Sidney’s An Apology for Poetry? Who’s sorry now?
