Pronunciation

  • Classical: [ˈpɫʊ.wi.ʊs][1]
  • Ecclesiastical: [ˈpluː.vi.us][1]

Forms

pluvius (feminine pluvia, neuter pluvium); first/second-declension adjective[1]

Etymology

It is from Latin pluō (“to rain”) + -ius.[2][3][1] De Vaan traces pluō to Proto-Italic *plow-e/o- (“to rain”) and Proto-Indo-European *pleu-e/o- (“to swim, float”), used figuratively of pouring rain; he compares Ancient Greek πλέω (pléō, “to sail, swim”).[4]

Earliest recorded meaning

De Vaan and the TLL date it from the Twelve Tables, which deal with rainwater that does damage.[4][3][5]

Semantic evolution

It is of rain: ⟨aqua pluvia⟩ is rainwater, and Lucretius explains how rainy moisture gathers in high clouds.[2][5] It is also rainy: Cato has rainy weather and Varro a rainy climate harmful to some crops.[5][2] ⟨Pluvius arcus⟩ is the rainbow in Horace.[2] Ovid has Danae conceiving Perseus from the golden rain.[2] The TLL notes that it is rarer after Pliny the Elder; the Romance words for rain, such as lluvia and chuva, come from the feminine pluvia.[3] Church Latin glosses it rainy.[6]

Timeline

  • Twelve Tables – of rainwater that does damage.[4][3][5]
  • 234–149 BC – Cato of rainy weather.[5][7]
  • 96–55 BC – Lucretius of rain in the clouds.[2][7]
