Pronunciation

  • IPA (Classical): [ˈpɫu.oː][1]
  • IPA (Ecclesiastical): [ˈpluː.o][1]

Forms

pluō (present infinitive pluere, perfect active pluī or plūvī); third conjugation, no supine stem[1]

Etymology

It is inherited from Proto-Italic *plow-e/o- (“to rain”), inherited from Proto-Indo-European *pleu-e/o- (“to swim, float”).[2] Cognate with Ancient Greek πλέω (pléō, “to sail”) and Sanskrit प्लवते (plávate, “floats”).[3] The present pluit was probably formed from the compound verbs, since one would expect *plovit, as with fluō.[2] The sense supposes that “to float” was used of pouring rain.[2]

Earliest recorded meaning

De Vaan dates it from Plautus, who says it had rained a lot.[2][3] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It was mostly impersonal, pluit “it rains”, and also meant to fall like rain, as Virgil's acorns raining from a shaken oak, and to rain down stones or blood, the prodigies Livy reports.[3][5] Early and late Latin also used it personally.[5] Plautus and Livy have a perfect plūvit.[5]

Timeline

  • c. 250–184 BC – Plautus says it had rained heavily.[3][4]
  • 70–19 BC – Virgil compares hail to acorns raining from an oak.[3][4]
  • 59 BC–17 AD – Livy reports rains of stones.[3][4]
