Have you heard or used this word before?
I first heard the word used in the movie "Night at the Museum," which came out in 2006.
Ben Stiller's character, a nightguard at the Museum of Natural History in New York, mentions that Attila the Hun -- ruler of the Hunnic Empire from 434 until 453, "surrounded himself with a phalanx of sorcerers and magicians."
Per Dictionary.com, phalanx could mean the following:
(1) any body of troops in close array
(2) a number of individuals, especially person's united for a common purpose
(3) a compact or closely massed body of persons, animals, or things
In other words, it's a unique way of saying:
I don't see phalanx being adopted in the corporate world anytime soon, but it's still a funky word nonetheless.
Next time someone asks what you plan to do this weekend, tell them you intend to go out with a phalanx of friends. I'm sure their reaction will be priceless!
