usufruct
To use and derive profit or benefit from property that belongs to another person.
figuratively
An enabling myth is just that—a myth that enables those who benefit from the status quo to keep on benefiting. Thorstein Veblen would say that it enabled the usufructuaries to keep on usufructing.
Where it comes from
From Late Latin ūsufrūctus, from ūsus + frūctus (“usage of the fruits of production”). Cognate with French usufruit, Italian usufrutto, usofrutto, Occitan usufrug, Portuguese usufruto, Spanish usufructo.
