Pronunciation

  • Classical: [maˈlɪŋ.nʊs][1]
  • Ecclesiastical: [maˈliɲ.ɲus][1]

Forms

malignus (feminine maligna, neuter malignum); first/second-declension adjective[1]

Etymology

It is from Latin male (“badly”) + -gnus (“born”), from the root of gignō (“to beget”), formed as the opposite of benignus (“kind, generous”);[1][2][3][4] compare prīvignus (“stepson”).[2] De Vaan lists it under both malus (“bad”) and ⟨gignō⟩, where he counts the compounds in ⟨-gnus⟩ “born” as the only inherited type, from Proto-Indo-European *-ǵnh₁-o-.[5] For ⟨malus⟩ he reports a possible Proto-Indo-European *mol-o- (“bad”), which he calls uncertain.[5]

Earliest recorded meaning

De Vaan dates it from Plautus,[5][4] in whom a man's character is tested, whether he is as he should be, “mean or generous”.[2]

Semantic evolution

Its first sense is ungenerous, grudging, from Plautus, Terence and Catullus on, and Virgil applies it to stingy soil and grudging hills.[2] Of things it is scanty, poor or narrow, as Virgil's narrow approaches.[2] From Horace on it is spiteful, ill-disposed: Horace scorns the spiteful crowd, and Virgil has ships watched with jealous eyes.[2] In Lucan and later poets it is harmful, unfavourable.[2] Lewis and Short call these senses mostly poetic and post-Augustan.[3]

Church Latin has it for malignant, evil, malicious, and as a noun an evildoer;[6] in Medieval Latin malignus as a noun is the Devil.[7] English malign (early 14th century) came from it through Old French maligne.[8]
