leko

leko is, at its core, squares, or things that behave like squares. Some find themselves using leko a lot more in highly urban environments. leko tend to tile. leko is sometimes 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. Any tiling pattern is leko too, even if the shapes are convex or unorthodox.

leko is common, but not as common as most words in this dictionary. Even among people who self-identify as leko users, the word is not used very often, so usage may differ from what's described here. People who don't use leko usually avoid talking directly about squares or tesselating patterns, which is pretty easy because of how uncommon the usecase is.
