The copper wire is called the ground wire because it is connected to the earth either directly or through another grounded conductor. It provides a 120 vac current source. It provides the return path for the current provided by the hot wire. By convention the white wire is neutral the black wire is hot and a green or bare wire is ground. The black wire is the hot wire. The white wire is called the neutral wire.
The neutral wire is connected to an earth ground. Green electrical wires green wires connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel. It provides the return path for the current provided by the hot wire. So if you see lots of different colors in an electrical box you probably need to call an electrician.

The purpose of a neutral wire is to connect to the neutral bus bar a conductive piece of metal within an electrical panel that attracts the electric current for distribution throughout the house.
