Etymology

Origin of defamatory

First recorded in 1585–95; from Medieval Latin diffāmātōrius, equivalent to Latin diffāmā(re) ( defame ) + -tōrious -tory 1

Explanation

Defamatory is a word used to describe statements that are untrue, slanderous, or libelous. Defamatory language often consists of harmful lies. Defamatory words — that is, words which defame — are words that can cause real damage. If someone said you were a secret unicorn hunter, that would be a silly, not defamatory, lie. If someone said you were a thief or a traitor, and you weren't, that would be defamatory. Public figures, like celebrities and politicians, are especially sensitive to defamatory statements about them.
