Couple, or pair, is a game plan wherein a group of machines, creatures or individuals are arranged one behind another, all looking in the equivalent direction.The first utilization of the term in English was couple harness,[citation needed] which is utilized for at least two draft ponies, or other draft creatures, bridled in a solitary line one behind another, rather than a couple, saddled one next to the other, or a group of a few sets. The couple saddle permits extra creatures to give pulling capacity to a vehicle intended for a solitary creature.
