Etymology

It is from Latin fluō (“to flow”),[2][3][1] probably a singular made from ⟨fluenta⟩, the neuter plural of the present participle fluēns (“flowing”), as Leumann explains it.[4] The verb goes back to Proto-Italic *flow-e/o- and Proto-Indo-European *bʰleuH- (“to flow over”).[4]

Earliest recorded meaning

De Vaan and Köbler record it first in Lucretius,[4][5] who speaks of fluenta lubrica, “slippery streams”.[3]

Semantic evolution

It is a word of poetry and of post-classical prose, used mostly in the plural for the waters of a stream or river: Virgil has Xanthi fluenta and Tiberina fluenta, and also the waters of a lake.[2][3] Lucretius once uses it for a current of air, and Apuleius for a stream of flames.[3]

The singular appears in Apuleius, Ausonius and Prudentius.[3] In the Vulgate it is used of the Jordan, and in Ecclesiastical Latin it means a river or running water.[3][6]

Timeline

  • 96–55 BC – Lucretius uses fluenta for streams.[4][3][5]
  • 70–19 BC – Virgil uses it of the Xanthus and the Tiber.[3][5]
  • c. 125–175 AD – Apuleius uses the singular, and the phrase “streams of flames”.[3][5]
  • 390–406 AD – The Vulgate uses it of the waters of the Jordan.[3][5]
