pluo

Latin

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

alternative form of pluit (“rain”)
- 44 BCE, Cicero, De Divinatione, section 2.58:
  Sanguinem pluisse senatui nuntiatum est, Atratum etiam fluvium fluxisse sanguine, deorum sudasse simulacra.
  It was reported to the senate that blood had rained down, that even the river Atratus had overflowed with blood, and that the statues of the gods had given off sweat.

Takes a subject, unlike the impersonal pluit.
