Laconic:

The region inhabited by the Spartans of ancient Greece was named Laconia.

Philip of Macedonia (the father of Alexander the Great) sent this warning to the famous warriors of the City, to frighten them into obedience: "If I enter Laconia with my army, I shall raze Sparta to the ground."

The Spartans replied with a single word: "If."

Laconic means "to the point", in recognition of the Spartan style.
