In ancient Korea, specifically from the late Koryo era to Lee's Korea era, it was used as a title for the imperial court or the royal family, and it did not distinguish between men and women, such as the mother of the palace, the mother of the queen and the mother of the king. Influenced by the Yuan Dynasty, this term was spread by Mongolian maids or princesses who married in Korea during the Korean era.

Mom can also be used in other places, in short, it is the most distinguished title.
