Pronunciation

  • Classical: [ˈfɫuː.mɛn][1]
  • Ecclesiastical: [ˈfluː.men][1]

Forms

flūmen n (genitive flūminis); third declension[1]

Etymology

It is formed from Latin fluō + -men, “that which flows”.[2][1] De Vaan derives the verb from Proto-Italic *flow-e/o-, from Proto-Indo-European *bʰleuH- (“to flow over”), comparing Ancient Greek φλύω (phlúō, “to boil over”) and Lithuanian bliáuti (“to bleat, sob”).[3][4]

Earliest recorded meaning

It is found from Ennius on:[4] per amoenam urbem lēnī fluit agmine flūmen, “through the pleasant city the river flows with gentle course”.[2]

Semantic evolution

Flūmen is a river or stream, and in poetry flowing water, a flood.[2][5][1] It is used of any flow of liquid or air, such as a stream of blood, often with exaggeration, and figuratively of a copious flow of eloquence or talent and an onrush of attackers.[2][1]

Timeline

  • 204–169 BC – First found in Ennius.[2][4]
  • 96–55 BC – Lucretius: sanguinis exspīrāns calidum dē pectore flūmen, “breathing out a warm stream of blood from the breast”.[2][4]
  • 81–43 BC – Cicero uses it of a river that suddenly rose.[2][4]

Döderlein says that fluvius and flūmen denote an ordinary stream, as opposed to a pond or lake, while amnis is a great and mighty river.[6]
