oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position.

Explanation:

The motion of a particle moving along a straight line with an acceleration which is always towards a fixed point on the line and whose magnitude is proportional to the distance from the fixed point is called simple harmonic motion [SHM].

These are Basic Conditions and characteristics for a body to exhibit SHM

A restoring force must act on the body.
Body must have acceleration in a direction opposite to the displacement and the acceleration must be directly proportional to displacement.

The system must have inertia (mass).
SHM is a type of oscillatory motion.

It is a particular case of preodic motion.

It can be represented by a simple sine or
cosine function.
