A tile is a manufactured piece of hard-wearing material such as ceramic, clay, stone, porcelain, metal or even glass. Tiles are generally used for covering roofs, floors, and walls, or other objects such as tabletops. The word is derived from the French word tuile, which is, in turn, from the Latin word tegula, meaning a roof tile composed of baked clay. Less precisely, the modern term can refer to any sort of construction tile or similar object, such as rectangular counters used in playing games.

Tiles are often used to form wall and floor coverings, and can range from simple square tiles to complex mosaics. Tiles are most often made from ceramic, with a hard glaze finish, but other materials are also commonly used, such as glass, slate, and reformed ceramic slurry, which is cast in a mould and fired.
