Hunting refers to the act of finding and killing a wild animal, either for sport or with the intention of using its parts to make food, clothes, etc. It commonly describes looking for something, especially for a job or flat, fluctuating around a central value without stabilizing, and the process of determining which of a group of telephone lines will receive a call, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to to find or search for an animal in the wild with the intention of killing the animal for its meat or for sport, to try to find something; search (for), and to drive; to chase; with down, from, away, etc, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Hunting as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Additional shades of meaning include to use or manage (dogs, horses, etc.) in hunting, to use or traverse in pursuit of game, and to be in a state of instability of movement or forced oscillation, as a governor which has a large movement of the balls for small change of load, an arc-lamp clutch mechanism which moves rapidly up and down with variations of current, etc.; also, to seesaw, as a pair of alternators working in parallel, which reinforce how the category can stretch across adjacent but still recognizable uses of the same term.
