inlay

This term describes a precise craft technique where a material is recessed into a surface to create a flush, decorative pattern. It carries a connotation of luxury, meticulousness, and permanence, as the materials are physically integrated rather than simply layered on top. It is most frequently encountered in discussions of fine furniture, jewelry, and architectural detailing.

As a noun, the word refers to the resulting ornament or the process itself. When used as a verb, it emphasizes the intentional act of embedding one substance into another to achieve a specific aesthetic effect, often contrasting with "overlay," where the material sits above the surface.
