Pronunciation

  • Classical: [sʊˈpɛr.fɫu.oː][1]
  • Ecclesiastical: [suˈpɛr.flu.o][1]

Forms

superfluō (present infinitive superfluere, perfect active superflūxī); third conjugation, no supine stem[1]

Etymology

It is from Latin super- (“over”) + fluō (“to flow”).[2][1] Fluō goes back to Proto-Italic *flow-e/o- and Proto-Indo-European *bhleuH- (“to flow (over)”).[3] Super goes back to Proto-Indo-European *(h1)uper(i) (“over, above”).[3]

Earliest recorded meaning

Lewis and Short call it mostly post-Augustan and find it only once in Cicero,[4] who in the Brutus says of himself as a young speaker redundantes nos et superfluentes iuvenili quadam dicendi impunitate et licentia, “overflowing and running over with a youthful freedom and licence in speaking”.[4][5] Catullus has superbus et superfluens, of a man overflowing with wealth.[2][5]

Semantic evolution

Literally it means to flow over the brim or sides, overflow, in Celsus of ingredients in a bronze vessel, and in Seneca, Pliny the Elder and Tacitus of the Nile and a spring;[2][4] Columella uses it of water flowing over a surface.[2][4] Tacitus applies it to an orator who is supra modum exsultans et superfluens, “bounding and overflowing beyond measure”.[2][4] It came to mean to be more than enough, superabound, and to be surplus to need, superfluous, as in Quintilian's nihil neque desit neque superfluat, “let nothing be lacking or superfluous”.[2][4] With an ablative it means to be superabundantly supplied with, as Aquileia with arms in Silius.[2][4] Once in Quintilian it is transitive, of words that would flow past the ears.[2][4]
