fluo

From Proto-Italic *flowō ^[1], from Proto-Indo-European *bʰlewgʷ-, from *bʰlew-, possibly from *bʰleh₁- ‎(“to swell, flow”). Cognate with Ancient Greek φλέω ‎(phléō, “to abound”), φλύω ‎(phlúō, “to boil over”).
Some do not exclude the supposition of it being from *srew- ‎(“to flow”) (with sr- > θr- > fr-), with contamination from pluit.

fluō ‎(present infinitive fluere, perfect active fluxī, supine fluxum); third conjugation

I flow, stream, pour
- 29 BCE – 19 BCE, Virgil, Aeneid 8.445
  Fluit aes riuis aurique metallum, uulnificusque chalybs uasta fornace liquescit.
  Bronze and golden ore flowed in streams, and steel, that deals wounds, melted in a vast furnace.
I am soaked in
