Screen


Definition:

  • (n.) Anything that separates or cuts off inconvenience, injury, or danger; that which shelters or conceals from view; a shield or protection; as, a fire screen.
  • (n.) A dwarf wall or partition carried up to a certain height for separation and protection, as in a church, to separate the aisle from the choir, or the like.
