Hence also lushburg (mid-14c.), Middle English word for "a base coin made in imitation of the sterling or silver penny and imported from Luxemburg in the reign of Edward III" [OED].
"pertaining to expense," c. 1600, from Latin sumptuarius "relating to expenses," from sumptus "expense, cost," from sumere "to borrow, buy, spend, eat, drink, consume, employ, take, take up," contraction of *sub-emere, from sub "under" (see sub-) + emere "to take, buy" (from PIE root *em- "to take, distribute").
ancient Roman silver coin, 1570s, from Latin denarius, noun use of adjective meaning "containing ten," and short for denarius nummus "the coin containing ten (aces)," from deni- "by tens," from decem "ten" (from PIE root *dekm- "ten"). In English money reckoning, "a penny," this having been, like the Roman denarius, the largest silver coin (hence d for "pence" in l.s.d.).

In medieval theology, "the virtue whose opposite is avarice, and whose excess is prodigality" [The Middle English Compendium]. For Old French suffix -esse, compare fortress. Related: Largation.
