Pronunciation

  • Classical: [ˈuːŋk.tʊs][1]
  • Ecclesiastical: [ˈuŋk.tus][1]

Forms

ūnctus (feminine ūncta, neuter ūnctum, comparative ūnctior); first/second-declension adjective[2]

Etymology

Used as an adjective, it is the past participle from Latin unguō (“to anoint”).[2][3][4] De Vaan traces unguō to Proto-Italic *ongʷ-e- (“to anoint”) and Proto-Indo-European *h₃engʷ-e/o- (“to anoint”), cognate with Umbrian umtu (“let him anoint”) and Sanskrit अनक्ति (anákti, “to anoint, smear”).[5]

Earliest recorded meaning

De Vaan dates the verb from Plautus, who also has the comparative diminutive unctiusculus “a little oilier”.[5] Köbler dates the adjective from Catullus.[4]

Semantic evolution

It is “oiled, greasy”, as the greasy water Horace's host will not serve his guests,[2] and so stands for rich food: Petronius has a full hand and a rich table, uncta mensa.[2] Cicero plays on “oiled” and “enriched” in a letter to Atticus.[2] The neuter ūnctum is a rich dish or banquet and an ointment,[1][6] and Church Latin has “anointed, smeared”.[6] Döderlein says that unctus is anointed with a pleasant ointment, beside the general dēlibūtus and oblitus, smeared with something unclean.[7]

Timeline

  • 81/79–52/50 BC – Catullus has the adjective.[4]
  • 81–43 BC – Cicero, of being oiled and enriched.[2][4]
  • 65–8 BC – Horace, of greasy water.[2][4]
  • before 66 AD – Petronius, of a rich table.[2][4]

Meanings

Adjective

  1. Covered or soaked with oil, oily, greasy;[2] anointed, smeared.[2][6]
  2. Rich, of food or a table; enriched.[2]

Noun

  1. (neuter, ūnctum) A rich dish, a banquet; an ointment.[1][6]

Usage notes

A separate fourth-declension noun ūnctus, -ūs, formed from the same verb, means “anointing”;[2][3][1] Apuleius has oleum unctui, oil for anointing, and Pliny the Elder uses it apparently of a sauce or dressing.[2][3][1]
