Eigenstates

an eigenstate = a microscopic “definite” state = a microscopic-classical state = a microscopic state corresponding to a macroscopic state

a microscopic state = a quantum state = an eigenstate or a superposition of eigenstates

A superposition state is not corresponding to any particular macroscopic state.

a macroscopic state = a definite state = a classical state

A macroscopic-classical state, in turn, is a superposition of a lot of microscopic states. A classical state is a superposition of a lot of quantum states.
