Forms
ōrātōrium n (genitive ōrātōriī); second declension[1][2] Manuscripts sometimes treat it as masculine or as a first-declension noun, and some write it with ⟨h⟩.[3]
Etymology
It is from Latin ōrātōrius (“of or for praying”), the neuter used as a noun, as if with templum understood.[1][4] It answers to Greek εὐκτήριον (euktḗrion).[3][5]
Augustine explained that nothing should be done in an oratory except what it was made for, from which it took its name,[3][6] and Isidore of Seville that it is consecrated to prayer alone, whence its name.[7][3]
Earliest recorded meaning
The TLL finds it from the Vulgate, Augustine and the Theodosian Code on.[3] In the Vulgate “Judith ingressa est oratorium”, Judith went into the place of prayer.[1]
Semantic evolution
In Late Latin it named any place set apart for prayer, whether in a church, a monastery or a martyr's shrine, and also chapels and churches themselves; it renders Greek words for a house of prayer.[3] Monastic rules have it for the oratory of the monastery, and the Rule of Benedict gives that a chapter of its own;[3] by metonymy it could mean the monks at prayer or their common prayer.[3]
Medieval Latin used it for a chapel in the legal sense, a church without full parish rights, a chapel next to a church, a basilica, a parish church or an abbey church, and even a kneeler.[8] Du Cange takes it as a palace in one passage of the Annals of Saint-Bertin for the year 877.[5] In modern canon law it is a place set aside, with the permission of the ordinary, for the worship of a community.[9]
It lives on in Old French oreor and Old Provençal orador,[3] and in Italian oratorio.[6] English oratory, a small chapel, comes from Late Latin, partly through Old French; the musical oratorio is named from the services held in the Oratory of Saint Philip Neri in Rome.[4]
