Pronunciation

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

Forms

languēscō (present infinitive languēscere, perfect active langüī); third conjugation, no passive, no supine stem[1] Lucan scans the perfect languit as three syllables.[2]

Etymology

It is from Latin langueō (“to be weak, faint”) + -scō, an inchoative.[2][1] De Vaan derives langueō from an adjective “faint, weak”, from Proto-Italic *(s)lā̆ng-u-, perhaps Proto-Indo-European *sl̥-n-ǵ-u-, a nasalised form of the root of laxus (“loose”).[3] Cognate with Ancient Greek λαγαρός (lagarós, “slack, thin”) and Old English slæc (“weak, slack”).[3]

Earliest recorded meaning

De Vaan dates it from Lucretius;[3] Catullus has “not before death makes my eyes grow faint”.[2]

Semantic evolution

It means to grow weak or feeble, and to fall sick, as Suetonius' Nero, ill only three times in fourteen years.[2] Of mental powers it is to fail, as Cicero's fear that the orator grows weak with age.[2] Of plants it is to droop or wilt, as Virgil's flower cut by the plough, and of moving things to lose force, as Ovid's wave dying down after a strong wind;[2] Curtius uses it of water cooling.[2] Of people it is to lose resolve or calm down, and of efforts and passions to flag, both in Cicero.[2] Church Latin glosses it “become weak, faint, languid”.[4]
