  • Ecclesiastical: [ˈlum.bus][1]

Forms

lumbus m (genitive lumbī); second declension[1]

Etymology

It is inherited from Proto-Italic *londwo- (“loins”), inherited from Proto-Indo-European *londʰ-u-o-.[2] De Vaan compares Sanskrit रन्ध्र (rándhra-, “loin of animals; weak spot on the body; cavity”), and the OLD and the TLL compare Old High German lentī, Old English lendenu and Old Norse lendir.[2][3][4] Gotō links these words with the Germanic word for land through a verb meaning to sink, a view LIV adopts.[2] Isidore says the loins were named from lust.[4]

Earliest recorded meaning

De Vaan dates it from Plautus and notes that it is usually plural.[2][5] In the OLD's earliest quotation Plautus has loins aching from sitting.[3]

Semantic evolution

It is the loins, the part of the body about the hips, and the phrase ⟨lumbōrum dolor⟩ is lumbago.[3] Cicero's Aratea has ⟨lumbōrum tenus⟩, as far as the loins.[6] The loins are also the seat of sexual excitement, as in Propertius, and an animal's loin as meat: in Laberius a cook who burns a loin is flogged.[3] Columella uses it of the lower part of a vine stem.[3] Wiktionary gives the plural sense genitals.[1] Niermeyer records medieval senses: a chine of pork, an egg yolk, a lance shaft, the top of a hill and an appurtenance.[7] English loin comes from a Vulgar Latin derivative through Old French, from the early 14th century.[8]
