Metronymics is a term that refers to the practice of naming individuals after their mother's name rather than their father's. This term is mostly used in anthropological studies to describe the different naming traditions in different cultures. There are a few synonyms that we can use to describe the same concept. These include matronymics, mother-names, mother-centered names, and mother-lineage naming. All of these terms are used to describe the way in which individuals are named based on their mother's lineage rather than their father's. Regardless of the term used, the concept remains the same and continues to be a fascinating study in different cultures around the world.
