Deposition


Definition:

  • (n.) The act of depositing or deposing; the act of laying down or thrown down; precipitation.
  • (n.) The act of bringing before the mind; presentation.
  • (n.) The act of setting aside a sovereign or a public officer; deprivation of authority and dignity; displacement; removal.
