I'm going to have to read this, I think - my mom and I are obsessed with those words (like maculate, which I've only seen in the wild twice).

I finally found out what gruntling is. Birds do it. Something about settling feathers. So disgruntled people have their feathers out of order.

Must read Disreputable History... time to go see if my library has it or if it must be inter-library loaned.
