The state of being too much; excess.
What a nimiety of ... riches have we here! I am quite undone.
--James J. Kilpatrick, "Buckley: The Right Word," [?]National Review, December 23, 1996
Just as daily life contains all the comforts of what one owns, there is also a natural shedding or forgetting and a natural dulling, otherwise one becomes burdened with a sense of nimiety, a sense (as Kenneth Clark put it in his autobiography) of the "too-muchness" of life.
--Nicholas Poburko, "Poetry, Past And Present: F. T. Prince's Walks in Rome," Renascence: Essays on Values in Literature, January 1, 1999
Nimiety is from Late Latin nimietas, from Latin nimius, "very much, too much," from nimis, "excessively."
