Pronunciation

  • IPA (Classical): [ˈsɛ.ni.ɔr][1]
  • IPA (Ecclesiastical): [ˈsɛː.ni.or][1]

Forms

senior m (genitive seniōris); third declension[1]

Etymology

It is the comparative of senex “old”,[2][1] whose base is Proto-Italic *seno- (“old”), from Proto-Indo-European *sen-(o-) (“old”).[3]

Compare Old Irish sen (“old”) and Sanskrit सन (sána, “old”).[3][1]

Earliest recorded meaning

Köbler dates it from Cicero (81–43 BC),[4] who says that hardly anyone was older than Cato in his time.[2]

Semantic evolution

As an adjective it meant older or elder, and comparatively old, as Virgil's “older Acestes”.[2] As a noun it meant an older man, and in the Roman census and army the seniores were the men above military age, over forty-five.[2]

In Christian Latin it was used of elders and presbyters, and in Medieval Latin it became a title of rank: a lord, a feudal lord, a husband, an abbot or prior.[4][1] From this came Italian signore, French seigneur and Spanish señor, and through Vulgar Latin *seior English sire and sir.[1][5] English senior was borrowed in the late 13th century, first as “the elder”.[5]

  • 666 – A charter uses senior for an abbess.[4]
  • late 13th century – English senior is recorded.[5]
