Defamation Meaning: When False Words Damage a Reputation

Law and societyNounLawUpdated 26 Oct 2026

The basic defamation meaning is harming a person's or a business's reputation by communicating a false statement of fact about them to other people. If you tell your neighbors that the local grocer sells rotten meat, knowing it is untrue, and customers stop coming, that is the kind of harm defamation law deals with.

Defamation is both an everyday word and a legal term. In law it has two main forms, libel and slander, and courts look at specific elements before deciding a case. This page gives a plain defamation definition, explains what usually has to be proven, lists common defenses, and notes how the US and India treat it.

Defamation meaning in law, piece by piece

Laws differ from place to place, but most systems built on the common law look for similar ingredients. To define defamation the way a court might, a claim usually needs:

  1. A statement of fact. Something presented as true, not clearly an opinion or a joke.
  2. Falsity. In most places, the statement has to be untrue. A true statement, however unkind, is generally not defamation.
  3. Publication. It was shared with at least one person other than the one it describes. Saying it only to the person's face is usually not enough.
  4. Identification. Listeners or readers could tell who it was about.
  5. Harm to reputation. It lowered the person in the eyes of others, or caused real loss, such as lost work.
  6. Fault. Depending on the system, the speaker was careless, or in some cases knew it was false or ignored obvious doubts.

Libel versus slander

LibelSlander
FormWritten, printed, posted or broadcastSpoken aloud
LastsLasting recordPassing words
ExampleA false online review claiming a dentist has no licenseTelling a crowd at a meeting that the treasurer steals funds, when it is untrue

Both are types of defamation. Many legal systems have traditionally treated libel as more serious because a written record spreads and lasts. Posts and comments online are usually treated as libel.

What is not defamation

  • True statements. Truth is a defense almost everywhere, though some laws also ask whether sharing it served a public purpose.
  • Clear opinion. "I thought the food was bland" is an opinion. "The chef uses spoiled food" is a claim of fact.
  • Obvious jokes and satire that no reasonable reader would take as fact. See our page on satire.
  • Privileged settings. Statements made in court, in parliament or in certain official reports are often protected.
  • Fair reporting of public records or proceedings, in many systems.
A customer writes, "The repair took three weeks and I felt the price was too high." That is a personal experience and an opinion. If she had written, "This shop steals parts from customers' cars," with no basis, she would be making a factual claim that could be defamatory.

How the US and India approach it

United States

Defamation is mainly a civil matter: the harmed person sues for money, not prison. Because free speech has strong protection, public officials and public figures face a higher bar. Since a 1964 Supreme Court ruling, they generally must show the speaker knew the statement was false or acted with reckless disregard for the truth, a standard called actual malice. Private people usually need to show only carelessness.

India

Defamation can be both a civil wrong and a crime. The criminal offense is now set out in Section 356 of the Bharatiya Nyaya Sanhita, which replaced Sections 499 and 500 of the Indian Penal Code. It can be punished with simple imprisonment of up to two years, a fine, both, or community service. The law lists exceptions, such as true statements made for the public good and good faith opinions on public conduct.

Consider this a broad overview. Rules differ by country and state and turn on the facts, so anyone who believes they were defamed, or who faces such a claim, should have a qualified lawyer look at the details.

Using defame and defamatory

The verb is defame: He claimed the article defamed him. The adjective is defamatory: a defamatory post, defamatory remarks. People also speak of a defamation suit, defamation case or claim for defamation.

  • The council member filed a defamation suit over a leaflet that falsely accused her of taking bribes.
  • The newspaper printed a correction after the restaurant owner said the story was defamatory.
  • Be careful in group chats; repeating a false rumor about a colleague can still be defamation.
  • The judge ruled that the review was honest opinion and not defamatory.

Word history

Defamation traveled from Latin into Old French and on to Middle English, starting from diffamare, to spread an evil report about someone. It is built from dis-, which here suggests spreading or undoing, and fama, report or reputation, the same root as English fame. So to defame is, quite literally, to undo someone's fame.

Courtroom and rights vocabulary has a home of its own under law, politics and society, for example malice, affidavit and doxxing.
