What Are Swear Words and What Are They Used For?

A swear word is a word or phrase that's generally considered blasphemous, obscene, vulgar, or otherwise offensive. Also known as swearing, bad word, obscene word, dirty word, and four-letter word.

"Swear words serve many different functions in different social contexts," notes Janet Holmes. "They may express annoyance, aggression and insult, for instance, or they may express solidarity and friendliness" (An Introduction to Sociolinguistics, 2013).

From Old English, "take an oath"

Examples and Observations

  • Spock: Your use of language has altered since our arrival. It is currently laced with, shall we say, more colorful metaphors, "double dumbass on you" and so forth.
    Captain Kirk: Oh, you mean the profanity?
    Spock: Yes.
    Captain Kirk: Well, that's simply the way they talk here. Nobody pays any attention to you unless you swear every other word. You'll find it in all the literature of the period.
    (Leonard Nimoy and William Shatner in Star Trek IV: The Voyage Home, 1986)
  • Uses of Swear Words
    "A final puzzle about swearing is the crazy range of circumstances in which we do it. There is cathartic swearing, as when we hit our thumb with a hammer or knock over a glass of beer. There are imprecations, as when we suggest a label or offer advice to someone who has cut us off in traffic. There are vulgar terms for everyday things and activities, as when Bess Truman was asked to get the president to say fertilizer instead of manure and she replied, 'You have no idea how long it took me to get him to say manure.' There are figures of speech that put obscene words to other uses, such as the barnyard epithet for insincerity, the army acronym snafu, and the gynecological-flagellative term for uxorial dominance. And then there are the adjective-like expletives that salt the speech and split the words of soldiers, teenagers, Australians, and others affecting a breezy speech style."

  • Social Swearing
    "Why do we swear? The answer to this question depends on the approach you take. As a linguist--not a psychologist, neurologist, speech pathologist or any other -ist--I see swearing as meaningfully patterned verbal behaviour that readily lends itself to a functional analysis. Pragmatically, swearing can be understood in terms of the meanings it is taken to have and what it achieves in any particular circumstance. . . .
    "Typically, a social swear word originates as one of the 'bad' words but becomes conventionalised in a recognisably social form. Using swear words as loose intensifiers contributes to the easy-going, imprecise nature of informal talk among in-group members. . . . In sum, this is jokey, cruisy, relaxing talk in which participants oil the wheels of their connection as much by how they talk as what they talk about."
    (Ruth Wajnryb, Language Most Foul. Allen & Unwin, 2005)
  • Secular Swearing
    "[I]t would appear that in Western society the major shifts in the focus of swearing have been from religious matters (more especially the breaching of the commandment against taking the Lord's name in vain) to sexual and bodily functions, and from opprobrious insults, such as coolie and kike. Both of these trends reflect the increasing secularization of Western society."
    (Geoffrey Hughes, Swearing: A Social History of Foul Language, Oaths and Profanity in English. Blackwell, 1991)
  • George Carlin on "Bad Words"
    "There are four hundred thousand words in the English language and there are seven of them you can't say on television. What a ratio that is! Three hundred ninety three thousand nine hundred and ninety three . . . to seven! They must really be bad. They'd have to be outrageous to be separated from a group that large. 'All of you over here . . . You seven, you bad words.'
    "That's what they told us, you remember? 'That's a bad word.' What? There are no bad words. Bad thoughts, bad intentions, but no bad words."
    (George Carlin with Tony Hendra, Last Words. Simon & Schuster, 2009)
  • David Cameron's "Jokey, Blokey Interview"
    "David Cameron's jokey, blokey interview . . . on Absolute Radio this morning is a good example of what can happen when politicians attempt to be down with the kids--or in this case, with the thirtysomethings. . . .
    "Asked why he didn't use the social networking website Twitter, the Tory leader said: 'The trouble with Twitter, the instantness of it--too many twits might make a twat.' . . .
    "[T]he Tory leader's aides were in defensive mode afterwards, pointing out that 'twat' was not a swear word under radio guidelines."

  • S***r W***s
    "[N]ever use asterisks, or such silliness as b-----, which are just a cop out, as Charlotte Brontë recognised: 'The practice of hinting by single letters those expletives with which profane and violent people are wont to garnish their discourse, strikes me as a proceeding which, however well meant, is weak and futile. I cannot tell what good it does--what feeling it spares--what horror it conceals.'"
    (David Marsh and Amelia Hodsdon, Guardian Style, 3rd ed. Guardian Books, 2010)
  • Supreme Court Rulings on Swear Words
    "The Supreme Court’s last major case concerning broadcast indecency, F.C.C. v. Pacifica Foundation in 1978, upheld the commission’s determination that George Carlin’s classic 'seven dirty words' monologue, with its deliberate, repetitive and creative use of vulgarities, was indecent. But the court left open the question of whether the use of 'an occasional expletive' could be punished.
    "The case decided Tuesday, Federal Communications Commission v. Fox Television Stations, No. 07-582, arose from two appearances by celebrities on the Billboard Music Awards.
    "Justice Scalia read the passages at issue from the bench, though he substituted suggestive shorthand for the dirty words.
    "The first involved Cher, who reflected on her career in accepting an award in 2002: 'I’ve also had critics for the last 40 years saying I was on my way out every year. Right. So F-em.' (In his opinion, Justice Scalia explained that Cher 'metaphorically suggested a sexual act as a means of expressing hostility to her critics.')
    "The second passage came in an exchange between Paris Hilton and Nicole Richie in 2003 in which Ms. Richie discussed in vulgar terms the difficulties in cleaning cow manure off a Prada purse.
    "Reversing its policy on such fleeting expletives, the commission said in 2006 that both broadcasts were indecent. It did not matter, the commission said, that some of the offensive words did not refer directly to sexual or excretory functions. Nor did it matter that the cursing was isolated and apparently impromptu. . . .
    "In reversing that decision, Justice Scalia said the change in policy was rational and therefore permissible. 'It was certainly reasonable,' he wrote, 'to determine that it made no sense to distinguish between literal and nonliteral uses of offensive words, requiring repetitive use to render only the latter indecent.'
    "Justice John Paul Stevens, dissenting, wrote that not every use of a swear word connoted the same thing. 'As any golfer who has watched his partner shank a short approach knows,' Justice Stevens wrote, 'it would be absurd to accept the suggestion that the resultant four-letter word uttered on the golf course describes sex or excrement and is therefore indecent.'
    "'It is ironic, to say the least,' Justice Stevens went on, 'that while the F.C.C. patrols the airwaves for words that have a tenuous relationship with sex or excrement, commercials broadcast during prime-time hours frequently ask viewers whether they are battling erectile dysfunction or are having trouble going to the bathroom.'"

  • The Lighter Side of Swear Words
    "'Tell me, son,' the anxious mother said, 'what did your father say when you told him you'd wrecked his new Corvette?'
    "'Shall I leave out the swear words?' the son asked.
    "'Of course.'
    "'He didn't say anything.'"
    (Steve Allen, Steve Allen's Private Joke File. Three Rivers Press, 2000)
