Did you know?

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.
