What are the function of the three wires in domestic electrical appliances? I’m hoping for a very basic explanation, assuming I don’t know anything about electrics.

Live supplies the electricity.
Neutral returns the electrical path to ground and is a grounded conductor. It completes the circuit.
The earth or "grounding conductor" is another grounded conductor that normally doesn't carry any significant current (except perhaps a small bit of leakage). It's there for safety so that if there is a ground fault that the circuit breaker can trip (or fuse blown). The metal chassis of an appliance will be tied to earth for safety reasons.
The earth and neutral are tied together at the panel and nowhere else.
