Explanation
Someone who's polygamous has more than one husband or wife. Polygamous societies still exist, but it's more common for most people today to be married to one person at a time. You can describe someone with seven husbands as polygamous, and you can also use the word to describe an animal with several mates as well as a plant with a particularly varied reproductive system. The Late Greek source is polygamos, "often married," which combines the roots polys, "many," and gamos, "marriage."
