What does lattice mean?
A lattice is an open framework made from strips, bars, or lines that cross one another, usually at regular intervals. Its familiar image is the wooden trellis used to support climbing plants, but the word also describes the regular arrangements found in crystals, molecular structures, and other technical fields. By extension, a lattice can mean any organized network of interconnected elements. The term is useful because it conveys both a physical pattern and the idea of a stable framework with spaces between its parts. In ordinary writing, it is more specific than a generic “network” and more visually suggestive than an abstract “structure,” while its scientific uses make it precise rather than merely decorative.
An open framework of crossed strips or bars, or a regularly arranged network of lines, points, or interconnected components.

The scientific senses refer especially to regular geometric or molecular arrangements.
To form or arrange something in a lattice or crisscross pattern.

Where does lattice come from?
The word comes through Middle English from an Anglo-French form related to Old French lattis, meaning a lattice or trellis. The Anglo-French word was borrowed from Medieval Latin lattice, which developed from a wider Latin tradition associated with frameworks of crossed strips. Its modern uses preserve the original sense of an open, regularly constructed framework, while later scientific applications extended the term to geometric and molecular arrangements.
