Ultimate origin

Pronunciation

  • Classical: [ˈmɛ.rũː][1]
  • Ecclesiastical: [ˈmɛː.rum][1]

Forms

merum n (genitive merī); second declension[1]

Etymology

It is the neuter of merus (“pure, unmixed”), used as a noun.[2][1] De Vaan traces the adjective to Proto-Italic *mero- and Proto-Indo-European *merH-o- (“remaining, pure”), and follows Puhvel in comparing Hittite marri (“just so, gratuitously”); the old comparison with Ancient Greek μαρμαίρω (marmaírō, “to sparkle”), which the OLD keeps beside Old English āmerian (“to purify”), seems to him unnecessary.[3][2]

Earliest recorded meaning

Plautus, Curculio, of a man who would drown himself in neat wine (ingurgitāre sē in merum).[4] De Vaan records the related merobibus, “drinker of neat wine”, in Plautus.[3]

Semantic evolution

Merum is wine not mixed with water;[2][4] Lewis & Short note that the word is poetic and post-Augustan in prose.[2][4] It often implies heavy drinking: Propertius' Centaurs carried off Ischomache in the middle of their wine, and Quintilian says Cicero would reproach Antony with merum et vomitum, “neat wine and vomiting”.[2][4] Poets also use it for the juice inside the grape (Ovid, Martial).[2]

Church Latin glosses it “wine”.[5]
