In technical aviation terms does a helicopter hover or does it fly

It does both. Hovering only refers to remaining in a stationary position. Flying refers to the motion of the helicopter when it is moving in a direction other than just up or down (ie forwards/backwards/sideways).

How does a helicopter fly?
A helicopter can take off and land vertically (straight up and down). It can fly in any direction, even sideways and backwards. It can also hover or hang in the air above a given place.
A helicopter gets its power from rotors or blades. When its rotors are spinning, a helicopter doesn't look much like an airplane. But the rotor blades have an airfoil shape like the wings of an airplane. So as the rotors turn, air flows more quickly over the tops of the blades than it does below. This creates enough lift for flight.

Flying is moving through the air, and as such, a helicopter does fly. The principles by which it flies are similar to that of an airplane. In a helicopter, the air moving over the surface of the rotors produces lift; this is done on an airplaine by the wings. The rotors are able to change their pitch and angles so that some of the lift moves the helicopter in a forward (or other ) direction and some of it keeps the aircraft aloft.
The largest difference between a helicopter and an airplain is that the helicopter is able to hover, move backwards, sideways and such.

It would only be hovering if the blades and everything were motionless... But, the blades are turning and acting as wings there for creating lift. Balloons hover because there is no wing action.
So your answer is Helicopters Fly. They do not Hover.

A plane gets lift from its wings from the thrust while travelling forwards, the helicopter gets lift from the rotation of its blades.
I would say a helicopter flies by hovering, but it is kind of arbitrary how you define the difference, in a propeller driven plane the propellers work in the same way as a helicopters blades do but in a horizontal way rather than vertical, and they provide lift by pulling the plane's wings forward through the air.
I suppose a helicopter is more direct than a plane in that it's blades don't require a wing to provide lift.

You can only hover if you're not moving relative to the ground when you move you're flying.

Both. "Hovering" is a form of flying.

fly id say but im not totally certain. although it does seem to hover doesn't it?

fly and hover

It flies, the lift is produced by the movement of the rotors, which are actually wings. Forward,sideways,backwards movement is controlled by the cyclic movement of the rotors,vertical movement is controlled by collective pitch, lateral movement is controlled by the pitch of the tail rotor
