Pronunciation

  • Classical: [ˈliː.bũː][1]
  • Ecclesiastical: [ˈliː.bum][1]

Forms

lībum n (genitive lībī); second declension[1] Nigidius has a masculine lībus (accusative plural lībos).[2][3]

Etymology

It is inherited from Proto-Italic *leifo- (“sacrificial cake”), inherited from Proto-Indo-European *h₂le/oibʰ-o-, from a root meaning grease for anointing; it may equally go back to *loifo-.[4][1] De Vaan, after Steinbauer, takes lībō (“to pour a libation”) to be a verb made from this noun, “to make a sacrificial cake”, and connects dēlibūtus (“smeared”).[4] Cognate with Ancient Greek ἀλείφω (aleíphō, “to anoint”) and ἄλειφαρ (áleiphar, “unguent”).[4][1]

The ancients had other ideas: Varro derived it from lībō, Ovid from Liber, the god of wine, and Isidore from libet (“it pleases”).[5]

Earliest recorded meaning

De Vaan and Köbler date it from Ennius.[4][6]

Semantic evolution

It is a kind of cake, usually used in sacrifices;[2][3] Cato gives a recipe for one, and Lewis & Short describe it as a cake of meal made with milk or oil and spread with honey.[2][3] Virgil has cakes of spelt placed under the food on the grass, Ovid rustic cakes, and Juvenal a house full of cakes for sale.[3] Wiktionary notes that such cakes were offered especially on birthdays.[1] Church Latin glosses it offering, cake offering.[7]
