Neutral dynamic stability means the response is not damped.

Explanation:
Neutral dynamic stability means the aircraft’s response after a disturbance neither dies away nor grows with time—the oscillations continue at constant amplitude. This corresponds to zero damping in the system, so the motion is not damped. If there is any damping, the oscillations fade out (damped), which is positive dynamic stability. If the motion tends to grow, the system is unstable. An instant return to the original attitude isn’t how a natural dynamic response behaves. So, describing the response as not damped best captures neutral dynamic stability.
