Matronymics is a naming convention where a person's surname is derived from their mother's name. This practice contrasts with patronymics, which are based on the father's name. Matronymics can be found in various cultures and may reflect lineage, heritage, or social status. In some societies, matronymics are used to emphasize maternal lineage, especially in matriarchal cultures. For example, in certain Indigenous communities, a child may take their mother's name to honor her role in the family. This approach highlights the importance of women in ancestry and can influence identity and social connections.
