possessor

The word "possessor" is built directly on the Latin verb possidēre, meaning "to have and hold, to occupy," which itself is a compound of potis ("able, capable") and sedēre ("to sit"). The literal sense of "sitting upon" or "being master in" evolved into the abstract legal and general concept of ownership. The agent suffix -or was attached to the verb stem to create possessor in Latin, denoting "one who owns or holds." This form was adopted into Middle English via Anglo-Norman and Old French, preserving the core logic of an agent (the -or) performing the action of possessing.
