Latin aeger

Pronunciation

  • Classical: [ae̯ˈɡreːs.koː][1]
  • Ecclesiastical: [eˈɡrɛs.ko][1]

Forms

aegrēscō (present infinitive aegrēscere); third conjugation, no passive, no perfect or supine stems[1]

Etymology

It is an inchoative, from Latin aegreō (“to be sick”) + -scō,[2][1][3] and that verb is derived from aeger (“sick”).[4][5] The grammarian Charisius already gave it as an inchoative made from the adjective, noting that such verbs from nouns have no perfect.[4] De Vaan traces the adjective to Proto-Italic *aigro- and Proto-Indo-European *h2eig-ro-.[5]

Earliest recorded meaning

It is found from Lucretius on,[5] who uses it of falling ill (morbīs aegrēscimus īsdem, “we fall sick of the same diseases”) and of the mind falling sick.[2][3]

Semantic evolution

Pliny the Elder writes that ravens fall sick for sixty days.[2] Virgil uses it of a state of mind that grows worse: Turnus' violence is aggravated by the attempt to heal it (aegrēscitque medendō).[2][6] Statius uses it of mental distress and of fretting at good fortune,[2] and Tacitus of someone made ill by long anxiety.[2][3]

In Late Latin it was used of the soul (Lactantius), of plants and fruit trees, and often by Ennodius and Macrobius of patients.[4]
