Pronunciation

  • IPA (Classical): [ˈpri.ɔr][1]
  • IPA (Ecclesiastical): [ˈpriː.or][1]

Forms

prior (comparative, neuter prius, no positive form, superlative prīmus); third declension[1]

Etymology

It is inherited from Proto-Italic *prī̆-jos- (“earlier, former”), a comparative of an adverb pri (“before”), which Festus records as meaning prae.[2] Its superlative is prīmus.[2][3] The PIE source Proto-Indo-European *pr(e)i (“before”) is uncertain in detail.[2]

Cognate with Paelignian prismu, Ancient Greek πρίν (prín, “before”) and Lithuanian priẽ (“at”).[2]

Earliest recorded meaning

It is found from Livius Andronicus onwards.[2] Köbler's first source is Ennius (204–169 BC).[4] In Plautus a girl is born of “an earlier woman”.[3]

Semantic evolution

It meant in front, ahead, as Nepos' priores pedes “forefeet”, the previous one, earlier or former, the earlier of two, and the first-mentioned.[3][5] It also meant preferred or superior, and logically prior.[3]

As a noun priores were forefathers, and in medieval Latin a prior was a predecessor in office, an abbot, the second monk after the abbot, or a provost of canons.[6][4] English prior is a borrowing, and priority comes from its Medieval Latin derivative priōritās.[7]
