Polygamy is the practice of being married to more than one husband or wife at a time.
The noun polygamy originated from the Late Greek word polygamos, meaning “often married.” While viewed as controversial, polygamy is a custom that has been practiced by humans throughout history. A tribal chief would marry numerous members from the tribe. It was a distinguishing characteristic of early Mormonism — founder Brigham Young had about fifty-five wives. In zoology, polygamy is the mating habit of animals with numerous mates, which means your pet might be a practitioner.
