Why “sumptuosity” is a great word
SUMPTUOSITY — [Noun] The quality of lavish, expensive magnificence. From Middle French *somptuosité* and Late Latin *sumptuositas*, from Latin *sumptuosus* ("expensive, costly") + *-itas* ("-ity"), with *sumptuosus* deriving from *sumptus* ("expense, cost"). Unlike "opulence," which suggests a brute abundance of wealth, or "frugality," which is a philosophy of restraint, sumptuosity is the deliberate artistry of expense. It is the weighted drape of velvet, the cold gleam of silver on linen, the cathedral hush of a room too costly to live in—a gorgeous argument against austerity, whispered in a language only money can speak.
