That means that either its speed, or its direction, or both, are changing.
An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).
An object that is accelerating may be slowing down, gaining speed, and changing direction.
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
According to the "Physics Classroom" website (refer to the link, below), an object changing its speed, whether increasing or decreasing, is said to be "accelerating".
The object's velocityi will change.

Accelerating...or was accelerating.
Accelerating
An object that is accelerating may slow down, speed up, or change direction.
An object with a constant (vector)velocity is not accelerating. An object with a constand (scalar)speed can actually be accelerating, a car with a constant speed that passes around a corner is changing direction and is subjected to a lateral acceleration.
If the force acting upon an object are balanced then the object must not be accelerating
moving
When an object slows down it is still accelerating.
