Maybe I’m just an information-stunted writer, but here’s a new word for me. Maybe for you, too?
Contronym.
(BTW, it was new to the dictionary here at TKZ, too . . . I had to add it.) But I digress.

Fun, huh?
What’s a contronym, you ask. It’s those words common to the English language that “can have opposite or contradictory meanings”. I found a website with a list of 75 contronyms. And there’s a slew of other websites you can check out if you’re feeling a bit contradictory this beautiful Friday.
I took the liberty of downloading this quick list for you, just to give you an idea of how these words “work”. (I hope you can read it.)
One of the cautions noted on this website is that, as an author, if we use one of these special words in our writing we must be clear in the context which meaning should be applied. It could get a bit confusing, right?
For instance, consider the word “aught”. If your character slams his fist down on the desk and yells, “Aught was paid!” the reader will deduce nothing was paid. Without the slamming and yelling or other contextual details, your reader won’t know if all was paid or nothing was paid.
TKZers, have you ever heard of contronyms? And can you come up with your own? (Maybe after your second or third cuppa joe?)
