Adj. Comprised of both good and evil.

There may be an opposite fault; for indeed upon the agathokakological globe there are opposite qualities always to be found in parallel degrees, north and south of the equator.
The Doctor, Robert Southey (1848)

Greek word for ‘good’ + Greek word for ‘bad’ + ‘-logical’ + Robert Southey = Agathokakological. Why would someone create such a big word? We must hope that his readers knew the Greek words necessary for understanding it. I’m not too surprised it didn’t catch on.

There are a lot of things out there that have both good and evil in them and just as many missed opportunities for using this lovely word to describe them. Come on writers!

Maybe the word would have had more life if Robert Louis Stevenson had used itย to describe the duality present in every personย in The Strange Case of Dr. Jekyll and Mr. Hyde.

Even so, it’s still a useful word. It will make you sound much smarter if you use this word instead of “bad-goodness” or “good-badness.”
