n. a set of straps and fittings by which a horse or other animal is fastened to a cart, plow, etc.
vt. to put a harness on (an animal)
vt. to control and use (natural resources or energy) for practical purposes
The word "harness" traces back to Old French harer (to equip or prepare for battle, related to "army") + the noun suffix -ness. Originally, it referred to military equipment or armor, later narrowing to straps for controlling animals. The modern sense of "utilizing resources" (e.g., "harness energy") metaphorically extends from the idea of controlling or directing force.
