Forms

ūnctiō f (genitive ūnctiōnis); third declension[1]

Etymology

It is from Latin unguō (“to anoint”) + -tiō,[2][1] and de Vaan lists it, from Plautus on, among the derivatives of that verb.[3] Unguō goes back to Proto-Italic *ongw-e- (“to anoint”) and Proto-Indo-European *h₃engʷ-e/o- (“to anoint”).[3]

Earliest recorded meaning

It is first found in Plautus,[3][4] who in the Stichus speaks of ūnctiōnēs Graecae sūdātōriae, Greek rubs with oil to make one sweat.[5][6][7]

Semantic evolution

Cicero tells of philosophers leaving a discussion to go and anoint themselves for wrestling (ūnctiōnis causā).[5][6] Celsus uses it often in medicine, Columella of daily anointing, and Seneca and Quintilian have it too;[6][5] Pliny the Elder uses it for the ointment itself.[5][6][7]

In Christian Latin it is the priestly anointing and consecration of the Vulgate,[7] and Cyprian uses it of the anointing with the sign of the cross.[7] In medieval Britain Bede uses it of the holy oil poured on the priest at his consecration; it was used of the anointing of kings and of the sick in danger of death, the extrēma ūnctiō, and in accounts of the greasing of shoes, carts and sheep.[8] It survives in Italian unzione.[7]
