Answer 1

The answer is Silence.
As, the riddle is popular one I think so

Answer 2

Answer: Silence

Explanation:

This riddle is a very famous and common one. Most people know the answer for this but as you either have no idea about this or you're testing everyone's knowledge out there, so, the answer will be silence.

Whenever we speak the first thing that is cut off or breaks is the silence around us (if there actually is silence).

But as a matter of fact when there is already much noise around you then if you even speak a thousand words, you won't be breaking silence.
