Pronunciation

  • Classical: [proːˈteːk.tɔr][1]
  • Ecclesiastical: [proˈtɛk.tor][1]

Forms

prōtēctor m (genitive prōtēctōris); third declension[1]

Etymology

It is from Latin prōtegō + -tor, an agent noun.[2][3]

Earliest recorded meaning

The TLL finds it from the Old Latin Bible, Tertullian and inscriptions of the 3rd century on.[3] Tertullian speaks of legum protectores, “protectors of the laws”.[4]

Semantic evolution

It meant one who protects, defends or guards;[3][2] an inscription quoted by the OLD calls Jupiter the protector of the emperor Marcus Aurelius Severus.[2] The Vulgate uses it of God in the Psalms.[4] In the Late Empire it was the title of a guard of the emperor's person, and later a high honorary rank;[4][1] Ammianus and the Theodosian Code use it so.[4] The word passed into Greek.[3]

In medieval Latin it was a patron and protector, also of God, Christ or a saint,[5] the title of the Cardinal Protector of the Franciscan order,[5] and in England the title of a regent ruling in the king's place.[5] English protector came in the late 14th century from Old French and directly from the Late Latin word.[6]
