Pronunciation

  • Classical: [rɛjˈjɛk.ti.oː][1]
  • Ecclesiastical: [reˈjɛk.t͡si.o][1]

Forms

reiectiō f (genitive reiectiōnis); third declension[1] The OLD writes it with a long first vowel, rēiectiō;[2] it is also spelled rējectiō.[3][1]

Etymology

It is from Latin rēiciō (“to throw back, reject”) + -tiō.[2][4][5] That verb is formed with re- from iaciō (“to throw”),[2] which goes back to Proto-Italic *jak-i- (“to throw”).[6]

Earliest recorded meaning

It is first found in Cicero,[7][5] who uses it of rejection in general, of renouncing citizenship, and of the challenging of jurors.[2][3]

Semantic evolution

In the De finibus Cicero pairs sēlēctiō and reiectiō, the choosing of what accords with nature and the rejection of what is contrary to it.[2][3] In the Pro Balbo it is the renunciation of a citizenship.[2][8] As a legal term it was the right of the prosecutor or the defendant to reject some of the jurors chosen by lot: in a letter Cicero writes reiectiō facta est clāmōribus maximīs, “the challenging was done amid loud uproar”.[2][3][9] Quintilian uses it of shifting a charge onto someone else,[9][10] and the rhetorician Julius Rufinianus of the dismissal of points that do not belong to the question.[10][8]

In a physical sense it meant throwing up: Pliny the Elder has sanguinis reiectiō, the spitting of blood, and the TLL finds it often in the medical writers.[2][3][5] In British Medieval Latin it was used of the expulsion of a disseisor from land and of vomiting.[11]
