Etymology tree
Forms
languor m (genitive languōris); third declension[1]
Etymology
It is from Latin langueō (“to be faint, weary”) + -or.[2][3][1] De Vaan takes the basis to be an adjective ⟨*lang-u(o)-⟩ faint, a nasalized variant of the root of laxus (“loose”), from Proto-Italic *(s)lā̆ng-u- and perhaps Proto-Indo-European *sl-n-ǵ-u- (“weak, faint”).[4] Cognate with Ancient Greek λαγαρός (lagarós, “slack, thin”) and Old English slæc (“weak”).[4]
Earliest recorded meaning
Köbler dates it from Plautus,[5] whose Asinaria speaks of a man whose toughness often wore out eight strong lictors.[2][6]
Semantic evolution
It is faintness, exhaustion or weariness, as Terence's “this walk has tired me”, and specifically sickness, as Horace's watery languor in a pale body.[2][6] Of the sea it is stillness, as in Seneca, and of gems a dullness of colour in Pliny the Elder.[2] Cicero uses it of inactivity and sloth, as minds softened by shade, pleasures, leisure and idleness, and of apathy and of the feeble style of the older writers.[2]
In Church Latin it is feebleness, sickness and infirmity.[7] In medieval Latin it is illness that excuses a party from appearing in court, and moral weakness or sin.[8] English borrowed languor about 1300, first in the senses disease and distress.[9]
