Laconic - Terse and concise
I still remember 666's fascination with Zach Snyder's movie "300" and the lengthy discourses he delved into before the movie was released. I never got around to watching the movie but the dialogues he listed on one of his posts stayed with me. Little did I know then, that they will lead me to origin of the word laconic. Laconia is the name of a region of Greece of which Sparta was the capital. The Spartans, noted for being warlike and disciplined, were also known for the bluntness of the speech and for their dry wit. And hence the word laconic!
Trivia: An example of a Spartan laconic exchange: When Philip II of Macedon turned his attention to Sparta after having key Greek city-states in submission, he sent a message: "If I win this war, you will be slaves forever." The Spartans sent back a one word reply: "If".
