Definition
Defamatory describes a statement, publication, or communication that tends to injure the reputation of a person in the eyes of the community — exposing them to hatred, contempt, ridicule, or diminished esteem. The term functions primarily as an adjective qualifying statements, words, or publications that form the basis of a defamation claim.
A statement is defamatory if, on its face or by necessary implication, it would lower the subject's reputation in the estimation of right-thinking members of society. Whether a statement is defamatory is typically a threshold legal question: if the statement cannot reasonably be read as defamatory, the claim fails at the outset, regardless of falsity or harm.
Two important distinctions flow from this:
1. Defamatory per se: Some statements are so inherently damaging — accusations of serious crime, loathsome disease, professional incompetence, or sexual immorality — that harm to reputation is presumed without proof of actual damages.
2. Defamatory per quod: Other statements appear innocent on their face but become defamatory only through extrinsic facts or context (the innuendo). The plaintiff must plead and prove those additional facts to establish the defamatory character.

Common Language
Modern common usage (Wiktionary): Damaging to someone's reputation, especially if untrue.
Historical common usage (Webster's 1913): Containing defamation; injurious to reputation; calumnious; slanderous; as, defamatory words; defamatory writings.
The common and legal meanings are closely aligned, but the ordinary usage underweights a critical legal distinction. Everyday speech treats "defamatory" and "damaging to reputation" as near-synonyms and implies falsity as a defining feature. In law, defamatory describes the character of the statement — its capacity to harm reputation — which is analytically separate from falsity, publication, fault, and damages. A true statement can be defamatory in character; under the common law it simply was not actionable (truth being a complete defense). Researchers working with historical sources must keep these elements disaggregated.

Common Confusion
DEFAMATORY vs. DEFAMATION: Defamatory is the adjective describing the nature of a statement. Defamation is the tort — the actionable wrong that arises when a defamatory statement is falsely made, published to a third party, and causes cognizable harm. Historical dictionaries sometimes use the terms interchangeably in loose definitions; the distinction matters acutely in pleading and in understanding how courts analyze each element independently.
DEFAMATORY vs. MALICIOUS: Anderson notes explicitly that a defamatory publication "is not necessarily malicious." This diverges from lay intuition. Malice — in the sense of knowing falsity or reckless disregard for truth — became a constitutionally required element for certain plaintiffs (public officials, public figures) through twentieth-century First Amendment doctrine. In historical sources predating that development, malice often carried a different, presumed meaning. Do not read modern constitutional malice requirements back into pre-twentieth-century sources.

Why It Matters in Research
The word defamatory appears at two distinct levels in legal sources: as a term of art describing the threshold quality of a statement, and as shorthand for the broader tort. Researchers must identify which usage is operative in any given source.
Historical sources — including Anderson — treat the defamatory character of a statement as almost entirely a question of harm to reputation, with falsity assumed or treated as a separate element. Modern doctrine, reshaped by constitutional law since the mid-twentieth century, substantially reorganized this framework. Fault requirements, the public/private plaintiff distinction, and presumed versus actual damages all interact with what it means to call a statement defamatory. Corpus research that moves across this doctrinal shift without flagging it will produce misleading results.
The per se / per quod distinction is present in historical sources but inconsistently applied. Some jurisdictions collapsed it; others maintained it rigorously. When researching historical cases, do not assume that courts are using these categories in the same way across time or across states.
The relationship between defamatory and the medium of publication — libel (written) versus slander (spoken) — was treated as foundational in early authorities, including Anderson. Modern law retains this distinction but applies it differently, especially as broadcast media, digital publication, and social platforms have complicated the written/spoken divide. Historical dictionary support is thin on these modern applications.

Historical Dictionary Support
Anderson's Dictionary of Law offers a compact and reliable baseline. Anderson correctly identifies the core functional definition — words that produce "perceptible injury to the reputation" — and correctly disaggregates the concept across its forms: defamatory words are actionable if false; written and published false defamatory words constitute libel; spoken ones constitute slander. The note that a defamatory publication "is not necessarily malicious" is a meaningful doctrinal observation that tracks the common law's traditional treatment of malice as a separate or presumed element rather than a definitional one.
What Anderson and comparable historical dictionaries do not address — because they could not — is the constitutional overlay imposed by later First Amendment doctrine. The restructuring of defamation law to require actual malice for public-figure plaintiffs, and the broader recalibration of the relationship between defamatory character, falsity, and fault, falls outside the horizon of nineteenth-century legal dictionaries. Researchers should treat historical dictionary definitions as accurate for their era and incomplete for modern practice.

Jurisdictional Note
The per se categories — which statements are defamatory without proof of special damages — vary by jurisdiction and have been modified in some states by statute. The constitutional malice requirement applies uniformly to public officials and public figures under federal First Amendment doctrine, but states vary in how they treat private-figure plaintiffs and what fault standard applies to matters of private concern.
