Paternal refers to the father or father's side of the family. It is typically used to describe traits or characteristics that are inherited from the father, as well as any relationships or relatives on the father's side. For example, a person's paternal grandfather would be their father's father, and their paternal aunt or uncle would be related to them through their father's side of the family. The term "paternity" is also used to refer to the legal or biological status of being the father of a child.
