plate-glass

The term 'plate-glass' is a compound that precisely describes its manufacturing origin. The word 'plate' entered English via French, carrying its sense of a broad, flat sheet from its Latin and Greek ancestors, which described something spread out. 'Glass' is a native English word of ancient Germanic lineage, ultimately from a Proto-Indo-European root associated with a shiny, lustrous appearance. Combined, the term literally means "glass in the form of a flat sheet," distinguishing it from blown or crown glass. Its modern association with large financial institutions stems from the imposing, transparent facades of 19th and 20th-century bank and corporate headquarters, which were symbols of solidity and prestige built using this material.
