That depends on the context.
In the case of a vehicle, if you "hot wire" the ignition it means that you have bypassed the keyswitch.
In the case of the electric service to your home or business, the HOT wire is the one that carries the current. The ground wire is literally connected to a rod that is driven into the ground. The neutral wire (according to code it should be white) is connected to the center tap of the transformer and if everything is functioning properly there should be little or now voltage potential to ground.

Electrical wire with clear insulation which wire is hot?
By "clear insulation," I assume you mean the type of wire used in some lamp cords. If so, the hot wire is the one with the smooth (non-ribbed) insulation.
If there are a red wire a black wire and a bare wire in a 120 volt supply wire which is the hot wire?
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
How hot does a hot wire strip heaters wire get?
Hot wire strip heaters are used for usually sealing two pieces of poly together to form a bag or band around an object. Due to the variable types of poly used and different manufactures specifications , one heat can not be used for all occasions. There is a thermostat that is added in line with the hot wire to control the temperature of the wire. This thermostat limits the heating of the wire so as to get the melting point of the poly just right. If a strip heating wire is left full on it will get red hot and usually burn itself up. Nickel chrome wire has a melting point of 1400 degrees C.
The black wire is hot but there is no current between the hot and neutral wire. There is current between the hot and ground wire?
You have a potentially deadly wiring problem in which the open neutral could mean someone accidentally switched off the white wire instead of the black wire, or some other horrible mistake. Please call a qualified electrician to diagnose this problem immediately.

What does an open neutral mean?
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
What is a 3 wire hot water system?
What do you mean by hot water system? If you mean hot water tank than a three wire hot water tank means that its 220 volt electric. If you have to ask than don't touch it
