There's no scarcity of English words used for too much of a good thing — words like "overkill," "plethora," "superfluity," "surfeit," "surplus," and "preponderance," to name a few. In fact, you might just feel that "nimiety" itself is a bit superfluous. And it's true — we've never used the word excessively, though it has been part of our language for nearly 450 years. (We borrowed it from Late Latin "nimietas," a noun taken, in turn, from the Latin adjective "nimius," meaning "excessive.") Superfluous or not, "nimiety" still turns up occasionally. For example, in his 1991 book Biblioholism: The Literary Addiction, about "the habitual longing to purchase, read, store, admire and consume books in excess," author Tom Raabe blames one bookstore's "nimiety of overstuffed chairs" for exacerbating this condition.
