noun
A grounded metal rod placed high on a structure to conduct electrical current from a lightning strike directly to the ground, preventing the currents from injuring people or animals or from damaging objects. Lightning rods usually have a sharp, pointed tip, since electric lines of force are more highly concentrated around pointed objects, in this case increasing the attractiveness of the rod compared with other nearby objects.
