The Free On-line Dictionary of Computing (30 December 2018):

lattice

    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.

   See also complete lattice, domain theory.

Easton's 1897 Bible Dictionary:

Lattice
   (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.
