Pronunciation

  • Classical: [ˈwɛ.ɡɛ.tʊs][1]
  • Ecclesiastical: [ˈvɛː.d͡ʒe.tus][1]

Forms

vegetus (feminine vegeta, neuter vegetum); first/second-declension adjective[1]

Etymology

It is from Latin vegeō (“to be active, rouse”).[2][3][1] De Vaan points out that a short ⟨e⟩ in this position is unexpected in Latin, so the second vowel is at most due to assimilation to the first, from an older ⟨*vegitus⟩.[3] The verb is related to Sanskrit वाजयति (vājáyati, “impels”) and Old High German wahhēn (“to be awake”); de Vaan notes that it died out after the Republic, Lucretius being the last author to use it.[3]

Earliest recorded meaning

De Vaan dates it from Varro,[3] who uses it in an etymology of vitulus “calf”: the word is from Greek, or because most calves are lively, vegeti.[2]

Semantic evolution

In Classical Latin it means vigorous and active, of people, animals and bodily movements such as the pulse, and of a lively rhythm.[2] Cicero applies it to the mind, which in sleep can show itself alert for dreaming, and Seneca the Elder to lively expression.[2] Pliny the Elder uses it of a vivid colour.[2]

Döderlein distinguishes it from vigēns, fresh and strong in body and mind, and vīvidus, full of life and energy: vegetus is alert and animated in mind.[4] In Ecclesiastical Latin it keeps the sense of strong, brisk and active.[5]

Timeline

  • 81–43 BC – Cicero applies it to the mind in sleep.[2][6]
  • 59 BC–17 AD – Livy contrasts tired soldiers with fresh and vigorous ones.[7][6]
