Forms

possīdō (present infinitive possīdere, perfect active possēdī, supine possessum); third conjugation[1]

Etymology

It is from Latin potis (“master, in control of”) + sīdō (“to sit down, settle”), the verb of entering possession beside possideō (“to possess”).[2][1] De Vaan traces potis to Proto-Indo-European *pót-i- (“master, lord”), and sīdō to Proto-Italic *sizd-e/o- (“to sit down”) and Proto-Indo-European *si-sd-e/o- (“to sit down”).[3]

Earliest recorded meaning

Lewis & Short's instances begin with Cicero, who in the De oratore has taking possession of someone's goods without a will,[1] and in the Verrines someone who had soon taken over the whole man and his whole praetorship.[1]

Semantic evolution

It is to take possession of, seize upon, as the Bellum Alexandrinum has of a kingdom.[1][2] With things as subject it is poetic and post-classical: Lucretius has air taking over all the void, Ovid the surrounding water occupying the farthest places, and Justin fire seizing everything.[1] The OLD discusses other possible instances under possideō.[2]

Timeline

  • 81–43 BC – Cicero, of taking possession of goods.[1][4]
  • 96–55 BC – Lucretius, of air filling the void.[1][4]
  • 43 BC–18 AD – Ovid, of water occupying the edges of the world.[1][4]
