Pronunciation

  • Classical: [ɪnˈjɛk.ti.oː][1]
  • Ecclesiastical: [inˈjɛk.t͡si.o][1]

Forms

iniectiō f (genitive iniectiōnis); third declension[1] Manuscripts of the Latin Oribasius often have enectio.[2]

Etymology

It is from Latin iniciō (“to throw in or on”) + -tiō.[3][1] The verb is made from in- and iaciō (“to throw”).[4]

Earliest recorded meaning

Its first record is the phrase manūs iniectiō in the Twelve Tables, as quoted by Gellius: after thirty days' grace for a confessed debt, post deinde manūs iniectiō estō “after that let there be a laying on of the hand”.[5][2][6]

Semantic evolution

In Roman law manūs iniectiō, the laying on of the hand, was the act by which a person seized someone on whom he had a legal claim, or property he claimed as his own, without a judge's decision.[3][5] Quintilian cites a law giving a patron this right over his freedman, and Seneca speaks of true goods on which no hand can be laid.[5] Outside this phrase the TLL finds the word only from Tertullian and the Old Latin Bible on, and never in poetry.[2]

Medical writers used it of an injection or enema, as Caelius Aurelianus and the veterinary writer Vegetius do.[5][2] Tertullian used it figuratively of the prompting of Satan and of an objection raised in argument.[5] Medieval Latin made manuum iniectiō the laying of violent hands on a person, above all on a cleric, which incurred excommunication;[7][8] it also kept the medical injection and the putting of an idea into someone's mind.[8] English injection comes from it, directly or through Old French, in the early 15th century.[4]
