Ground is more common in North American English, and earth is more common in British English.) Under normal conditions, a grounding conductor does not carry current. Neutral is a circuit conductor that normally carries current back to the source, and is connected to ground (earth) at the main electrical panel. In the electrical trade, the conductor of a 2-wire circuit connected to the supply neutral point and earth ground is referred to as the neutral.
In residential wiring, convention is that the black wire is hot and the white wire is neutral. This means that, if the circuit is wired correctly - and there is no fault in the circuit - the white wire should not have any potential difference (voltage) relative to ground.
