Lattice – /ˈladəs/ – noun

  1. a structure consisting of strips of wood or metal crossed and fastened together with square or diamond-shaped spaces left between, used typically as a screen or fence or as a support for climbing plants.
  2. an interlaced structure or pattern resembling this.
  3. a regular repeated three-dimensional arrangement of atoms, ions, or molecules in a metal or other crystalline solid.

Note: It should be stated, for the record—such that this is—I first heard this word used in conjunction to warp cores and dilithium crystals.
