Preoccupy v. t. (past & past part. preoccupied; pres. part. preoccupying)
To take possession of before another; as, to preoccupy a country not before held.
To prepossess; to engage, occupy, or engross the attention of, beforehand; hence, to prejudice. "I Think it more respectful to the reader to leave something to reflections than to preoccupy his judgment."
... There was a little money and this hut, and—Marie-Josephine. So I came here; and I write children's stories—that sort of thing.... It goes well enough. I sell a few to American publishers. Otherwise I shoot and fish and read ... when war does not preoccupy me...." ... — Barbarians • Robert W. Chambers
