Forms

diffāmātiō f (genitive diffāmātiōnis); third declension[1][2] Medieval texts also spell it defamatio.[3][4]

Etymology

It is formed from Latin diffāmō (“to spread abroad, publish”) + -tiō.[1][5][2] The verb is made of dis- and fāma (“report, rumour”) with a verbal suffix.[6]

Earliest recorded meaning

The first author to use it is Zeno of Verona, meaning the spreading or making public of something.[5]

Semantic evolution

In Late Latin it meant a publishing or spreading abroad: Augustine uses it of the reception and spreading of the Christian religion.[1][5][2] Medieval writers kept this neutral sense,[7] but the usual medieval meaning was the spreading of an evil report: defamation, slander.[7][4][8][9] British sources also use it for an accusation.[4]

English defamation comes from it, partly through Old French,[10] and so does Italian diffamazione.[11]
