Pronunciation

  • Classical: [ˈrɛ.fɫu.oː][1]
  • Ecclesiastical: [ˈrɛː.flu.o][1]

Forms

refluō (present infinitive refluere, perfect active reflūxī, supine reflūxum); third conjugation, no passive[1]

Etymology

It is from Latin re- (“back”) + fluō (“to flow”).[2][3][1] De Vaan traces fluō to Proto-Indo-European *bhleuH- (“to flow over”).[4]

Earliest recorded meaning

Lewis and Short call it poetic and post-Augustan.[5] Virgil has it in the Georgics and the Aeneid, where a terrified river flows backwards and the Nile withdraws from the fields.[5][6][7]

Semantic evolution

Ovid's Maeander “flows back and flows on” in its winding course,[5][8] and Lucan has rivers flowing back when blocked.[8][8] Mela and Pliny the Elder use it of the sea ebbing.[8][2] Valerius Flaccus uses the participle of the Po overflowing its banks.[8] In law Ulpian uses it of water flowing back onto land from a swamp in flood.[2] Cassiodorus has it as a transitive verb, to drive back.[7]
