Pronunciation

  • Classical: [sʊˈpɛr.sũː][1]
  • Ecclesiastical: [suˈpɛr.sum][1]

Forms

supersum (present infinitive superesse, perfect active superfuī, future active participle superfutūrus); irregular conjugation, suppletive, no passive, no supine stem except in the future active participle, no gerund[1] The parts are sometimes separated or inverted, especially in poetry: Virgil has iamque adeō super ūnus eram, “and now I alone was left”.[2][3] Ennius and Accius have an inceptive form superescit with the force of a future.[2][3]

Etymology

It is formed from Latin super- (“above, over”) + sum (“to be”).[2][1] super goes back to Proto-Italic *super and Proto-Indo-European *upér (“over, above”), with an added ⟨s-⟩ as in sub;[4] sum goes back to Proto-Indo-European *h₁es- (“to be”).[4]

Earliest recorded meaning

The OLD's first citation is Plautus: sī quid super illī fuerit, id nōbīs sat est, “if anything is left over for him, that is enough for us”.[2] Ennius has sibi memorat ūnum superesse labōrem, “he says one task remains for him”.[2]

Semantic evolution

Superesse is “to be left over, remain” (Cato of the space between two trees), and of persons “to remain alive, survive”.[2][3][1] It is “to remain to be done”, “to be still available” to someone, and “to be more than is needed, superfluous”.[2][1] Less often it is “to be above, on top of” and “to be superior to”, and of an advocate “to stand by” a client.[2][1]

Church Latin glosses it “be over and above, remain, be left, be superfluous, survive, suffice”.[5]
