Pronunciation

  • Classical: [mas.kʊˈliː.nʊs][1]
  • Ecclesiastical: [mas.kuˈliː.nus][1]

Forms

masculīnus (feminine masculīna, neuter masculīnum, comparative masculīnior, superlative masculīnissimus, adverb masculīnē or masculīniter); first/second-declension adjective[1]

Etymology

It is from Latin masculus (“male”) + -īnus.[2][3][1] The TLL compares fēminīnus (“female”),[3] and Etymonline suggests the diminutive base may have been chosen to pair with it.[4] The base is a diminutive of mās (“male”),[1][4] which de Vaan traces to Proto-Italic *mās- and Proto-Indo-European *meh2-(ō̆)s.[5]

Earliest recorded meaning

De Vaan and the OLD first record it in Varro, quoted by Augustine: the earth has a twofold power, masculine because it produces seed and feminine because it receives and nourishes it.[5][2]

Semantic evolution

Lewis & Short note that it is not in Cicero and perhaps not before Augustus.[6] It was used of the male sex in people, animals and plants (Pliny the Elder has round turnips “of the male sex”),[6] of male genitals in Phaedrus,[3][6] and in grammar of the masculine gender, as in Quintilian and in Caesellius Vindex, quoted by Gellius, who says that Ennius made cor masculine.[2][6] A variant reading in Quintilian gives it the sense “manly”.[6]

In Late Latin the Vulgate has imāginēs masculīnās, images of males,[3] and Pomponius, in the Digest, speaks of children of the masculine and feminine sex.[3] English took it through Old French as masculine, first for the grammatical gender.[4]
