Linguistic Note
The word tessellation derives from the Latin tessella, meaning small square.
A tessella was a small cubic piece of material used to make mosaics.
The word tessella itself derives from tessera, the Latin word for square.
This in turn derives from the Greek word τέσσερα (tessera), one of their words for four.
The verb form of tessellation is tessellate.
Hence when a tessellation can be formed from congruent copies of a polygon or a set of polygons, the polygon or set of polygons is said to tessellate the plane.
