Why this word is great
PHOTOGLYPHY — [Noun] A 19th-century process of engraving a design onto a surface by the direct, corrosive action of light. From the combining form photo- (from Greek phōs, meaning "light") and the Ancient Greek γλυφή (gluphḗ, meaning "carving, engraving"), with the English suffix -y forming a noun. Unlike "photogravure" (a later, tonal intaglio method for printing) or "photoengraving" (a broad, commercial term for photomechanical platemaking), photoglyphy evokes the primal marvel of light itself as a sculptor's chisel. It is the sun slowly inscribing its arc on a solarium floor, the ghostly tracery of a fern fixed onto a sensitized pewter plate, and the precise, acid-bitten line where a filtered sunbeam has burned away a protective ground—a fragile victory of sun over stone, a fossil of radiance.
