If you’ve ever been told to “take your time” when you actually are taking your time, or called “Sherlock” after stating the obvious, you’ve encountered sarcasm — a form of speech that can feel uncomfortable and cutting.
The word “sarcasm” has violent roots. It comes from the Greek sarx, meaning “flesh,” and sarkasmos, literally “tearing flesh.” By the second century A.D., Greek grammarists had shifted sarkasmos into a metaphor for a biting remark, according to Armand D’Angour, a professor of classical languages and literature at Oxford. One early definition, from the grammarist Tryphon, described sarcasm as “showing one’s teeth while smiling.” D’Angour notes that metaphors were necessary to describe verbal attack because terms like “assault” and “tear” were typically physical.
The term moved into Latin as sarcasmus. In the first century A.D., the Roman rhetorician Quintilian described sarcasmus as a kind of irony that pretends kindness while wounding. English adopted the word by dropping the Latin -us ending, as often happens with classical-language nouns. Written uses likely appeared after the spoken term, and the word’s history doesn’t follow a single line; it overlaps with irony and mocking.
Today, sarcasm is commonly understood as saying the opposite of what you mean with the intent to insult. A passenger who says “way to go” after a driver makes the wrong turn is using sarcasm; the remark, while brief, can leave the recipient feeling puzzled or hurt, says Delphine Dahan, who runs a psycholinguistics lab at the University of Pennsylvania.
Dahan explains why sarcasm can be hard to receive: “You’re in a bind. You cannot really be angry at the person … because they can say ‘I didn’t really mean it. I was pretending.'” Roger Kreuz, a psycholinguistics researcher and associate dean at the University of Memphis, adds that sarcasm is useful in American culture because it’s often considered impolite to be directly negative. “So by saying the opposite, you’re just brilliant,” he says.
Some people proudly describe sarcasm as part of their humor, but that may conflate sarcasm with irony. Sarcasm and irony are related: both can involve saying the opposite of what one means, but irony often carries a lighter intent. For instance, after a season of storms someone might wryly observe, “What a mild winter we’re having” — an ironic remark that isn’t aimed at insulting anyone. Thus, sarcastic remarks can be ironic, but irony is not necessarily sarcastic.
Sarcasm can also serve to exclude. When two people use sarcastic comments as an inside joke about a third person, it creates an air of exclusivity and can be critical of the outsider. Kreuz says that while the target’s flesh isn’t literally torn, the effect can still be wounding.
