Etymology and origin of the Latin word ilia

Confidence
Unknown
First attested
81/79–52/50 BC, Catullus

Forms

īlia n pl (genitive īlium); third declension[1][2] Lewis & Short list it under a singular īle.[3] Singular forms are rare and partly conjectural.[1]

Etymology

De Vaan finds no etymology: the Germanic words that Walde and Hofmann compared have a short vowel, and the Greek ἴλια (ília) “female parts”, a gloss of Hesychius, may be a borrowing from Latin.[2][1] Köbler cites Pokorny's Proto-Indo-European *īli-.[4]

Earliest recorded meaning

De Vaan and Köbler date it from Catullus,[2][4] who has a lover bursting the loins of all.[1]

Semantic evolution

It is the side of the body from the hips to the groin, the flanks.[1][2] In medicine Celsus places it between the hips and the pubes at the bottom of the belly.[1] It is used especially of the groin or private parts, as in Catullus.[1] As a cut of meat it is the flank: Horace has the untasted flanks of a turbot and Martial those of a boar.[1] It is also the guts: Horace exclaims at the tough guts of reapers.[1]

Timeline

  • 81/79–52/50 BC – Catullus of a lover's loins.[1][2][4]
  • 65–8 BC – Horace of a turbot's flanks and of reapers' guts.[1][4]
  • 14–37 AD – Celsus in medicine.[1][4]

Noun

  1. (plural) The side of the body from the hips to the groin, the flanks; the groin.[1][2]
  2. The flank as a cut of meat.[1]

Usage notes

Īlia is also a poetic name of the mother of Romulus and Remus, Rhea Silvia, from Ennius on.[1][3]
