What does tessellated mean?
Tessellated describes a surface made from, or decorated with, small pieces arranged in a close, mosaic-like pattern. The pieces may be square tiles, fragments of stone, glass, or other materials, and “tessellated” can also suggest a precise repeating geometric design. The word is especially common in architecture, archaeology, decorative arts, and descriptions of floors, walls, domes, and pavements. It has a formal, somewhat technical tone but remains intelligible in ordinary contexts. Historically, the term refers to tesserae, the small pieces used in mosaics. In modern use, “tessellated” can describe both an actual mosaic and a pattern that resembles one. The related verb “tessellate” means to fit pieces together in this manner or to decorate a surface with them.

Where does tessellated come from?
The word comes through Medieval Latin from Latin tessellatus, meaning formed with tesserae or small tiles. Latin tessera itself derives from a diminutive related to Greek tessis, “four,” referring to a small four-sided piece. English later developed the adjective “tessellated” and the related noun “tessellation,” both of which preserve the word’s association with tiles and mosaic work.
How tessellated is actually used
The adjective is formal and technical but established in general English, especially in descriptions of architecture, floors, walls, and decorative art. The verb form is comparatively rare and usually refers to forming a surface from tesserae or fitting geometric pieces together.
