Pronunciation

  • Classical: [seːˈjʊŋ.ɡoː][1]
  • Ecclesiastical: [seˈjuŋ.ɡo][1]

Forms

sēiungō (present infinitive sēiungere, perfect active sēiūnxī, supine sēiūnctum); third conjugation[1] It is also spelled sējungō.[1][2]

Etymology

It is from Latin sē- (“apart”) + iungō (“to join”).[3][1] De Vaan traces iungō to Proto-Italic *jung-e/o- and the nasal present Proto-Indo-European *(H)iunégti (“to yoke”).[4] Cognate with Ancient Greek ζεύγνυμι (zeúgnumi, “to yoke”), Lithuanian jùngti (“to tie, join, yoke”) and Hittite iuk- (“yoke”).[4]

Earliest recorded meaning

De Vaan dates it from Lucretius,[4] who has things “be separated and set apart”.[2]

Semantic evolution

It means to separate, part or isolate, as Cicero writes that a clause may either be joined to a decree of the senate or separated from it and written out by itself.[3][2] It also means to exclude or dissociate, as Cicero's son writes that jesting is not excluded from study and daily discussion.[3] A further sense is to separate mentally, distinguish: Cicero speaks of a wisdom in doing and speaking that cannot be separated.[3] Lewis & Short compare abiungō and disiungō.[2] Church Latin glosses it to disjoin, sever, separate.[5]

Timeline

  • 96–55 BC – Lucretius of things separated.[2][4][6]
  • 81–43 BC – Cicero of separating a clause and of inseparable wisdom.[3][6]
