Pronunciation

  • Classical: [ˈprae̯.fɫu.oː][1]
  • Ecclesiastical: [ˈprɛː.flu.o][1]

Forms

praefluō (present infinitive praefluere); third conjugation, no perfect or supine stems[1]

Etymology

It is from Latin prae- (“in front, past”) + fluō (“to flow”).[2][3][1] fluō goes back to Proto-Italic *flow-e/o- and Proto-Indo-European *bʰleuH- (“to flow over”).[4] De Vaan compares Ancient Greek φλύω (phlúō, “to seethe, boil over”) and Lithuanian bliáuti (“to bleat, sob”).[4]

Earliest recorded meaning

The TLL finds it first in Horace and Livy:[3] Horace has the waters that flow past fertile Tibur, and Livy the Tiber flowing past at the bottom of a valley.[2][5]

Semantic evolution

It is used of rivers and other water, either intransitively, to flow past, or with an accusative, to flow past a place.[2][6] Horace has the Aufidus flowing past the realms of Daunus, Pliny the Elder the same river flowing past Canusium, and Tacitus a river flowing past a camp and the Danube past the province of Noricum.[2][7][6] Columella advises building a farmhouse above a river that flows past, Tacitus has a river with an uncertain ford, and Florus waters at a strait that seemed to sing along with pipes and lyres.[2][5] An inscription uses it of water in a pipe.[7]

Lewis and Short call it rare and perhaps not older than Augustus.[7] In the manuscripts it is often confused with perfluō and prōfluō.[3]
