What is the term for a man having several wives at the same time?

The term for a man having several wives at the same time is polygyny. This practice refers specifically to a form of polygamy where one man is married to multiple women simultaneously. Polygyny is culturally significant in various societies around the world and can be associated with social, economic, and sometimes religious factors.

In contrast, polyandry refers to a woman having multiple husbands, while polygamy is the overarching term that encompasses both polygyny and polyandry. The levirate marriage, on the other hand, is a specific arrangement where a man marries the widow of his deceased brother, not related to having multiple spouses at the same time. Understanding these terms is essential in the study of family structures and marriage practices across different cultures.
