I. a cake, pancake of meal, made with milk or oil, and spread with honey, Cato, R. R. 75: rustica liba, Ov. F. 3, 670: adorea liba per herbam Subiciunt epulis, Verg. A. 7, 109; Ov.

Origins

Disputed. * According to De Vaan, from either Proto-Italic *leiβom or *loiβom, from Proto-Indo-European *h₂leybʰ-o-m or *h₂loybʰ-o-m respectively, from *h₂leybʰ- (“(anointing) grease”). If this theory were accepted, then the term would be cognate with Ancient Greek ἀλείφω (aleíphō, “to anoint”), ἄλειφᾰρ (áleiphăr, “unguent”). * The linguist Roman Garnier alternatively suggests that it is deverbal from lībō.
