Pronunciation

  • Classical: [eː.ɫaŋˈɡʷeːs.koː][1]
  • Ecclesiastical: [e.laŋˈɡʷɛs.ko][1]

Forms

ēlanguēscō (present infinitive ēlanguēscere, perfect active ēlangŭī); third conjugation, no passive, no supine stem[1] Valerius Flaccus scans the perfect elangŭit with a short ⟨u⟩.[2][3]

Etymology

It is from Latin ē- + languēscō (“to grow weak”).[2][3][1] The base is the inchoative of langueō (“to be faint”),[4] which de Vaan traces to Proto-Italic *(s)lā̆ng-u-, an adjective meaning “faint, weak”, a nasalised variant of the root of laxus (“loose”).[4] His Indo-European reconstruction, Proto-Indo-European *sl-n-ǵ-u- (“weak, faint”), carries a question mark.[4]

Earliest recorded meaning

The TLL's earliest instance is a fragment of Varro, quoted by Nonius, in which the common good of a state grows weak through the discord of its citizens.[3]

Semantic evolution

Livy uses it of people who lose their vigour and of an undertaking that slackens through delay: differendo … elanguit res, “by putting it off, the matter lost its force”.[2][3] Velleius uses it of an enemy's strength, Tacitus of soldiers worn out by expense and idleness, and Celsus of the pulse.[2][3] Florus and the De viris illustribus say that Hannibal grew slack.[3]

In the Vulgate all the inhabitants of the land “grow faint”, and Gregory the Great uses it of the prophet Daniel's illness.[3] Ecclesiastical Latin keeps the sense “grow weak or faint”.[5]
