Writers are readers, by and large, and also word collectors. We tend to fall in love with words. Some writers make a career of writing about words as well as with them.
One of my personal favorites is dudgeon. In the Chesapeake Bay Mysteries, Van reflected on Nora being truly formidable when in high dudgeon. And from my rural Ohio roots, I like caddywampus and whopperjawed (both of which mean, basically, out of kilter or poorly constructed) as well as redd, as in redd up the table (meaning clear away or make ready).

Advice to Writers
If you choose to use colorful, unusual words such as these, use each only once in a given story or novel. They will be noticed. The only exception is would be when a given word is a speech tag for a given character.
Not to worry. The world is full of rich language, plenty to go around!
