leko

leko is, at its core, squares, or things that behave like squares. I find myself using leko a lot more in highly urban environments. leko tend to tile. I've seen leko used to describe most common polygons, and though squares are definitely most common and prototypical, hexagons in video games and on pavements are also leko, and any tiling pattern is leko too, even if the shapes are convex or unorthodox.

leko is a relatively uncommon word. It's likely the least widespread and used word in this list, so usage you observe may differ from what I describe here.
