Brevity is the soul of wit.

The proverb praises the ability to express an intelligent or amusing thought in few words. Extra explanation can weaken a point that would otherwise be sharp.

It treats economy of language as a sign of judgment, not merely a preference for short sentences. The aim is to say enough to make the thought clear, then stop.

Use it to encourage a shorter speech, explanation, or joke when the central point is getting lost. It can also serve as a pointed response to someone who has gone on too long.
