Pronunciation

  • Classical: [ˈprɔp.tɛr][1]
  • Ecclesiastical: [ˈprɔp.ter][1]

Forms

propter (+ accusative)[1]

Etymology

It is formed from Latin prope + -ter, for ⟨*propiter⟩, like inter and subter.[2][3][4][1] De Vaan follows Dunkel in explaining prope “near” from an iterative preverb Proto-Indo-European *própro (“on and on, ever further”), with the second ⟨r⟩ lost by dissimilation.[4]

Earliest recorded meaning

It is found from Naevius on;[4] Plautus has in … vīllā proxumā propter mare, “in the house nearest by the sea”.[2]

Semantic evolution

As an adverb propter means “near, close at hand” (ubi aqua propter siet “where there is water near by”).[2][3] As a preposition with the accusative it means “near, close to”, hence “because of, on account of”: of the cause of a state of affairs, of a motive, of a person through whom something happens (“thanks to”), of a means, and of a purpose or person for whose sake something is done; it also means “as regards”.[2] It often follows its noun, especially a pronoun (quem propter).[2]

In Medieval Latin it marks a purpose, “for, aiming at”, and after verbs of sending “for, to fetch”.[5] It is used in the phrase post hoc, ergō propter hoc “after this, therefore because of this”.[1]
