Word of the Day -- Phalanx

Phalanx: a body of heavily armed infantry in ancient Greece formed in close deep ranks and files; broadly : a body of troops in close array.  

The original sense of "phalanx" refers to a military formation that was used in ancient warfare and consisted of a tight block of soldiers standing shoulder to shoulder, several rows deep, often with shields joined. The word "phalanx" comes from the Greeks, though they were not the only ones who used this formation. The Greek term literally means "log" and was used for both this line of battle and for a bone in a finger or toe. The word and its senses passed into Latin and then were adopted into English in the 16th century. These days, a "phalanx" can be any arranged mass, whether of persons, animals, or things, or a body of people organized in a particular effort.
