Unappropriated

a.
  1. Not specially appropriate; having no special application.
  2. Not granted to any person, corporation, or the like, to the exclusion of others; as, unappropriated lands.
  3. Not granted for, or applied to, any specific purpose; as, the unappropriated moneys in the treasury.
