The word laconic refers to the Spartan pride in avoiding verbosity.

I still remember an anecdote illustrating an early laconicism. At a parley before a battle, a Persian general attempted to intimidate a Spartan general by boasting: "When our archers shoot, the sun will be darkened by their arrows!" The Spartan general replied: "Good. We will fight in the shade."

When a messenger dispatched by an enemy army announced, "If we enter
Laconia, we will raze it to the ground!," the laconic response the Laconians sent back was simply: "If."
