  • IPA (Ecclesiastical): [proˈtɛk.t͡si.o][1]

Etymology

It is from Latin protego (“to cover in front, protect”) + -tiō.[2][1]

Earliest recorded meaning

Tertullian uses it of the protection of faith, in his work on flight in persecution.[3][4] Köbler dates Tertullian c. 160–220 AD.[5]

Semantic evolution

Lewis & Short call it post-classical, first a covering over and then protection.[3] A title in the Digest uses it of covering with a projecting roof, and a declamation ascribed to Quintilian of defence.[4] Ambrose speaks of the protection of arms, and the Vulgate of God's protection in the Psalms.[3][4] Glossaries explain it as defence, support and help.[6]

In medieval Latin it was used in law codes, charters and formulae.[5] English protection is recorded in the mid-14th century as shelter or defence.[7]
