Etymology tree
Forms
obsecrātiō f (genitive obsecrātiōnis); third declension[1] The spelling opsecrātiō is also found.[2]
Etymology
It is from Latin obsecrō (“to beseech, implore”) + -tiō.[2][1][3] The verb is formed from ob- and sacrō (“to consecrate”),[1] and de Vaan lists it among the derivatives of sacer (“sacred”), which he traces to Proto-Italic *sakro- and Proto-Indo-European *sh2k-ro- (“sacred”).[4]
Earliest recorded meaning
Köbler dates it from Cicero,[5] whose De inventione lists among the commonplaces of an appeal for pity one made through entreaty, per obsecrātiōnem.[2]
Semantic evolution
It means a beseeching or imploring, an entreaty or supplication:[2][6] Cicero also uses it in his speeches and letters, and Quintilian speaks of entreating the judges by all they hold dearest.[2] The TLL finds it in Cicero, Livy and Quintilian, but not in the poets.[3] In religion it was a public act of prayer to the gods: Livy describes a supplication made by the people with the duumvirs leading the words, and Suetonius one held after a bird of ill omen was seen on the Capitol.[2]
The Vulgate uses it for prayer,[6] and Church Latin kept the senses prayer, entreaty and public prayer.[7] British medieval writers, from Alcuin on, use it for entreaty and prayer, and also for a part of the Mass.[8]
