the.com/veneer

A beautiful lie, 0.6 millimeters thick, glued to something cheaper.

means A thin, attractive surface layer — literally a sliver of fine wood (or figuratively, a polished show of manners or quality) covering something plainer underneath.

from From French fournir, 'to furnish or provide,' which traveled into German as furnieren and then English as 'veneer' — originally a cabinetmaker's term for facing cheap wood with a thin layer of something finer. The literal woodworking sense came first; the 'fake sophistication' meaning is a later, very logical extension — if you can furnish a table with a pretty face, why not a person.
