Why is a class called an abstraction of an object?

Question

I understand that a class is essentially a plan of an object, but the idea that a class is an “abstraction” of an object will make it a little harder for me to wrap my head ... If anyone could tell me the real meaning of the expression: “A class is object abstraction, "I would be very grateful.

My confusion is that this statement has been interpreted differently by different people ...

Does abstraction mean:

• Work with the basics of the system, not the deep subtleties of this system?

or it means that:

2. Only an abstract class can be considered as an abstraction of an object?
