His delineations of character and action, if executed with ability, will have a raciness and freshness about them, which will attest their fidelity, the secret charm, which belongs to truth and nature, and with which even the finest genius cannot invest a system, of adscititious and imaginary manners.
-- Catharine Maria Sedgwick, "Clarence," 2011
Adscititious comes from the Latin word adscītus which meant "derived, assumed, foreign."
