If you have me, you want to share me. If you share me, you no longer have me. What am I?

How to think about it

1. Most things can be shared and kept at once, like food or a joke. This one cannot, so sharing must destroy it.
2. Think of things whose whole value is that other people do not know them.
3. The hint says to whisper. What do people whisper to one friend and beg them not to repeat?
4. A secret stops being a secret as soon as it is shared.

Why “a secret” is the answer

A secret exists only while it is kept, and the temptation to tell someone is what makes secrets hard to keep. The moment you share it, it is just information, so you no longer have a secret. The riddle captures that tension in two short sentences.

Common wrong answers

• A cold. You can share a cold and still have it, which is the opposite of the second line.
• Money. Giving money away means you have less, but sharing it does not make it stop being money.
