The term "coated" refers to something that is covered or wrapped with a thin layer of material. This can be done for various purposes such as protection, decoration, or to alter the texture of an object. The coating could be made from materials like paint, varnish, wax, or any other substance that sticks to the surface it's applied on. In general usage, "coated" is often used in relation to medications where a layer of material is placed over the active ingredient to control its release into the body.
