Pronunciation

  • Classical: [ˈɛf.fɫoː][1]
  • Ecclesiastical: [ˈɛf.flo][1]

Forms

efflō (present infinitive efflāre, perfect active efflāvī, supine efflātum); first conjugation[1] The older spelling is ecflō.[2][3]

Etymology

It is from Latin ex- + flō (“to blow, breathe”).[2][1][3] De Vaan tentatively traces flō to Proto-Indo-European *bʰleh₁- (“to blow”), and thinks it may be related to fleō (“to weep”).[4]

Earliest recorded meaning

The TLL reads it first in Plautus, in the Persa, with the old spelling ecflāre.[3]

Semantic evolution

It means to breathe or blow out: Lucretius has the sun blowing out its fires,[5] Virgil the Chimaera breathing out Etna's fires from its throat and the horses of the Sun breathing out light,[2][5] and Ovid fire from mouth and nostrils.[5] Animam efflāre is to breathe one's last: Gaius Gracchus tells of a herdsman beaten until he died.[2] Varro uses it of the wind blowing away small creatures, and Catullus of horns sounding a blast.[2] Of things it is to give off vapours or moisture, as in Seneca's earth,[2] and Lucretius uses it of particles losing all their colour.[2] Ennius has it intransitive, of jets of blood spurting out.[2] Petronius uses it of someone babbling out all he had to say.[2] Lewis & Short call it mostly poetic and post-Augustan.[5] Stelten gives "give forth, breathe out" for Church Latin.[6]
