A matronymic is a name derived from a mother or female ancestor, often used to indicate lineage or family heritage. This naming convention contrasts with patronymics, which are based on the father's name. Matronymics can be found in various cultures and may take different forms, such as adding a suffix to the mother's name or using her name directly. In some societies, matronymics are more common than patronymics, especially in matriarchal cultures. For example, in Iceland, surnames often reflect the mother's name, such as Jónsdóttir for a daughter of Jón. This practice highlights the importance of maternal lineage in certain communities.
