Forms

reductus (feminine reducta, neuter reductum, comparative reductior); first/second-declension adjective[1][2]

Etymology

It is from Latin redūcō (“to lead back, draw back”): its perfect passive participle, used as an adjective.[1][2] That verb is a compound of re- and dūcō (“to lead”), which goes back to Proto-Indo-European *deuk-e/o- (“to draw”).[3]

Earliest recorded meaning

Cicero pairs producta and reducta to render two Stoic terms, things to be preferred and things to be passed over.[2] As an adjective of place it appears in Virgil,[4] who has a wave split itself into deep-set bays: in sinus scindit sese unda reductos.[1][2]

Semantic evolution

Of places it means drawn back, deep-set, and so retired or remote: Virgil and Horace both speak of a secluded valley.[1][2] Horace uses it figuratively when he calls virtue a mean between vices, drawn back from either extreme.[2] In Quintilian it is a painter's term for parts of a picture set back and made less prominent.[1][2]

Timeline

  • 81–43 BC – Cicero uses the neuter plural for Stoic things to be passed over.[2][4]
  • 70–19 BC – Virgil uses it of a deep-set bay and a secluded valley.[1][4]
  • 65–8 BC – Horace uses it of virtue removed from both extremes.[2][4]
  • c. 35–95/96 AD – Quintilian uses it of parts set back in a painting.[1][4]
