Pronunciation

  • Classical: [waˈɫeːs.koː][1]
  • Ecclesiastical: [vaˈlɛs.ko][1]

Forms

valēscō (present infinitive valēscere, perfect active valuī); third conjugation, no passive, no supine stem[1]

Etymology

It is from Latin valeō (“to be strong, be well”) + -ēscō, an inchoative.[2][1][3] De Vaan traces valeō to Proto-Italic *wal-ē- and Proto-Indo-European *h2ulh1-eh1- (“to be strong”).[4]

Earliest recorded meaning

Its first author is Lucretius,[2][3] who writes of children drinking the bitter juice of wormwood, deceived but not harmed, and rather restored so that they grow well: recreata valescat.[2]

Semantic evolution

It means to become sound in health, to grow strong,[2][3] and more widely to become powerful or gain ascendancy:[2] Tacitus says that as the Germans grew stronger most of the states took up arms against Rome, and that crimes grow strong by haste and good plans by delay.[2][3] Lewis & Short call it rare and note that Cicero does not use it.[3] Ambrose uses it of the juice by which the whole body grows strong.[3] In Church Latin it is to grow strong.[5]

Timeline

  • 96–55 BC – Lucretius, of a child restored to health.[2][3][6]
  • 98–115 AD – Tacitus, of the Germans growing powerful.[2][6]
  • c. 340–397 AD – Ambrose, of the body growing strong.[3][6]
