appropriation (n.)

late 14c., "the taking of (something) as private property," from Late Latin appropriationem (nominative appropriatio) "a making one's own," noun of action from past-participle stem of appropriare "to make one's own," from Latin ad "to" (see ad-) + propriare "take as one's own," from proprius "one's own" (see proper). Meaning "act of setting aside for some purpose" (especially of money) is attested by 1727.
