Dactylion

Dactylion (noun): The tip of one's middle finger.

"I wasn't sure if he was simply showing me his dactylion or intended to insult me."

Nihilarian

Nihilarian (noun): One who does useless work; practicing matters of no importance.

This is an interesting word because it comes from the Latin nihil meaning "nothing." A nihilist (a philosophical term)  is one who argues that life is without objective meaning, purpose, or intrinsic value. But if it's his or her work that is without meaning, purpose, or value, he or she is described as a nihilarian.

Which begs the question, is it possible to be an overworked nihilarian and yet not be a nihilist?

Peenge

Peenge (verb): To complain in a whiney voice.

This word sounds like what it is -- there is just no way that a word like peenge could mean forceful or aggressive.

"The editor was getting sick of the author's constant peenging about royalties."

Mytacism

Mytacism: Excessive or wrong use of the sound of the letter m.

Roman grammarians seeking to classify vitia ("errors in language") borrowed this term from the Greek mytakismos (my refers to the letter mu).

One of the most egregious examples of mytacism is when people say "ok" by adding an m-sound at the start so it is pronounced "mmmmkay," or when they say "bye" by doing the same and so pronouncing the word as "mmmmbye."

Misomaniac

Misomaniac (noun): Someone who hates everything and everyone. A person who values nothing and holds almost everything in contempt.

I know, I thought it referred to someone with a real addiction to a particular type of Japanese soup.

"I hear that Berrett-Koehler's Editorial Managing Director is just a bitter and angry guy -- a real misomaniac."

Sesquipedalian

Sesquipedalian (adjective): Characterized by long words; long winded.

How ironic that a word that describes long-winded wordiness is in itself long-winded.

"Many authors resort to sesquipedalian language to mask the fact that they don't know what they're talking about."

Abibliophobia

Abibliophobia (noun): The fear of running out of having reading material.

You may laugh at this, but many people experience milder forms of this condition every day. For example, if you are a voracious reader and you commence a long plane journey only to realize you accidentally left behind all your books, you will experience a mild form of abibliophobia.

You will always recognize the abibliophobic personality at a breakfast table. He or she is the one who momentarily panics when there is no newspaper or magazine in sight and then proceeds to read the contents of the cereal box.
