• A distinction is drawn by some Latin classicists between the ablātīvus īnstrūmentī, which is used to denote the cause in active sentences, and the ablātīvus reī efficientis, which is used in passive sentences. For example:
  • Ablātīvus īnstrūmentī:

  Deus mundum sōle illūstrat.

  God lights the world with the sun.

  • Ablātīvus reī efficientis:

  Sōle mundus illūstrātur.

  The world is lit by the sun.
