a man who is married to your mother, but who is not your father
My stepfather used to treat me like his real daughter.
The stepfather played a supportive role in the lives of his stepchildren.
Forming a connection with a stepfather can contribute to a stable family environment.
A stepfather may take on parental responsibilities, contributing to a child's upbringing.
The stepfather-daughter dance was a heartfelt moment at the wedding celebration.
