IPA: /ˈɪnˌleɪər/
KK: /ˈɪnˌleɪər/
A person whose job is to insert decorative materials into a surface, often to create patterns or designs.
The inlayer carefully placed the pieces of wood into the table's surface to create a beautiful design.
Inlayer is formed from "in-" (meaning within) and "layer" (from Old French *laier*, meaning to lay or put down). The word refers to something that is laid or placed within layers.
Think of something being 'put down' ('layer') 'within' ('in-') other layers — that's what inlayer means.
