Wall


Definition:

  • (n.) A kind of knot often used at the end of a rope; a wall knot; a wale.
  • (n.) A work or structure of stone, brick, or other materials, raised to some height, and intended for defense or security, solid and permanent inclosing fence, as around a field, a park, a town, etc., also, one of the upright inclosing parts of a building or a room.
