n.

c.1300, from Old French latiz “lattice,” from late “lath, board, plank, batten” (Modern French latte), from Frankish or some other Germanic source, cf. Old High German latta “lath;” see lath).
lattice
(lāt’ĭs)
A set of points that, when joined together, form the geometric shape of a mineral crystal. The lattice of the mineral halite, for example, is in the shape of a cube. See more at crystal.

theory
A partially ordered set in which all finite subsets have a least upper bound and greatest lower bound.
This definition has been standard at least since the 1930s and probably since Dedekind worked on lattice theory in the 19th century; though he may not have used that name.

(1.) Heb. ‘eshnabh, a latticed opening through which the cool breeze passes (Judg. 5:28). The flat roofs of the houses were sometimes enclosed with a parapet of lattice-work on wooden frames, to screen the women of the house from the gaze of the neighbourhood. (2.) Heb. harakim, the network or lattice of a window (Cant. 2:9). (3.) Heb. sebakhah, the latticed balustrade before a window or balcony (2 Kings 1:2). The lattice window is frequently used in Eastern countries.
