What is the origin of tinselry?
Tinselry, “cheap and pretentious display,” is an obvious combination of the noun tinsel and the noun suffix –ry (a form of –ery). Tinsel, though, is an interesting word. It is a shortening of Middle French estincelle “spangle, spark” (source of the English noun stencil), from Old French estencele, estincele “a spark, flash,” from an unrecorded Vulgar Latin stincilla, a transposed variant of Latin scintilla. By the 14th and 15th centuries, French had lost the pronunciation of the s in es-, and estincelle developed into modern French étincelle. In Anglo-French the initial e– also disappeared, giving tencel, tincel. The earliest Middle English examples show tinsel, tinselle used as an adjective in tinselle satin, satin made to sparkle or glitter by brocading with or interweaving gold or silver thread, or by overlaying the satin with a thin coating of gold or silver. Tinselry entered English in the 19th century.
