What does plate mean?
A plate is a flat dish used for serving food, a thin sheet of material such as metal or glass, or a broad, rigid section of the Earth's crust. The word also has technical and decorative senses: a plate may be a structural component in a machine, a dental appliance, or a surface layer applied to another object. In everyday use, “a plate of food” means a portion served on a dish, while “metal plate” suggests a sheet or panel used in construction or manufacture. “To plate” means to cover something with a thin layer, such as food, chocolate, or metal. These meanings share the idea of something relatively flat and bounded. The word is especially useful because it connects ordinary household objects with scientific vocabulary, industrial materials, and processes such as plating and plated coatings.
A flat, usually rigid dish on which food is served, or a thin sheet of material such as metal, glass, or wood.

The geological sense, referring to a rigid segment of the Earth's crust, is a specialized technical usage.

Where does plate come from?
The word comes through Old French from the Latin plattus, meaning “broad, flat, or level.” In English it first referred chiefly to a broad, shallow dish made of metal or precious material. The meaning extended to thin sheets of metal and, later, to the flat sections of the Earth's crust. Related forms such as platter, plateau, and platitude reflect the same broader tradition of flatness or levelness.
