Pronunciation

  • Classical: [ɪn.tɛrˈfʊn.doː][1]
  • Ecclesiastical: [in.terˈfun.do][1]

Forms

interfundō (present infinitive interfundere, perfect active interfūdī, supine interfūsum); third conjugation[2][3][4] The perfect participle interfūsus is by far the commonest form.[5][6]

Etymology

It is from Latin inter- + fundō1 (“to pour”), “to pour between”.[1][5][4]

Earliest recorded meaning

Its earliest use is in Virgil's Georgics, in noviēns Styx interfūsa, the Styx flowing nine times between,[5][3] a line he repeats in the Aeneid.[5]

Semantic evolution

It was used mostly in the passive and the participle, of water lying or flowing between lands: Horace has the seas poured between the shining Cyclades,[3][7] and Seneca, Pliny the Elder and Pliny the Younger use it of seas and the ocean that divide.[5] By extension it meant spread here and there: Virgil describes Dido maculīs interfūsa genās, her cheeks flecked with spots,[6][3] and Ammianus uses it of spots.[3] Statius has nox interfūsa, an intervening night.[2][3]

The active, “to pour between, sprinkle among”, appears in Avienus.[2][8] Orosius uses it of a wall bound with bitumen poured into it,[5] and Ambrose figuratively of a flood of worldly luxury.[5] Medieval writers used the participle of the Britons cut off by the ocean and of black scattered among white.[9]

  • 23/24–79 AD – Pliny the Elder uses it of the ocean.[2][5][10]
