Fatherly; behaving as or characteristic of a father. Received or inherited from one's father. Acting as a father; as in "paternal filicide" (murder of a son committed by his father).
Example sentence: To most of us, adulthood means being able to earn a living, possess a home, get married and rear children, and this implies having autonomy or control over one's life.
