What does inlay mean?
Inlay names both an action and the result of setting one material into another. As a verb, to inlay a surface is to insert a contrasting or decorative material into it, as in a cabinetmaker inlaying a chest with mother-of-pearl. As a noun, an inlay may mean the inserted material itself, the finished decorative design, or a specially fitted dental restoration placed within a prepared tooth. The word is especially associated with skilled craftwork, where a precisely shaped piece is embedded in a surrounding surface without necessarily being raised above it. Although inlay often evokes luxury, it can describe practical work as well as ornament. It is distinct from a veneer, which coats a surface, and from a general inset, which focuses more on the recessed area or inserted element than on the craftsmanship and material involved.
To set material into a surface, especially in a decorative or precisely fitted design.
"He inlaid the cabinet doors with thin strips of ebony."
The past tense is inlaid, and the present participle is inlaying.
A piece of material inserted into a surface, a decorative design made by this process, or a dental restoration fitted into a prepared tooth.
"The chest has a geometric inlay of mother-of-pearl."
The plural is inlays. The dental use specifically refers to a restoration occupying a prepared cavity within a tooth.
Used for individual pieces of inserted or decorative material and for separate completed inlay designs.
"The cabinet is decorated with floral inlays."
From cabinetmaking to dentistry, an inlay turns a plain surface into something more decorative—and sometimes helps a tooth withstand years of chewing.

Where does inlay come from?
The word combines the prefix in- with lay, expressing the idea of laying something in another material. Its development reflects the long-established English practice of embedding pieces of wood, metal, stone, or other materials in a contrasting surface. The related words overlay and underlay preserve the same verb lay, while the dental sense developed from the notion of a piece fitted into a cavity in a tooth.
