What is a step brother or step sister?

Answer 1

When your mother or father gets married to a person and that other person already has a child of their own, that child is considered a step brother/sister since they are not biologically related to you. However if your mother or father marries or is involved with another person and has a biological child with that person then that child is considered your half brother/sister since there is a biological relation to you.

Answer 2

if your mother/father get married to another person and that another person has a little girl/boy that is your step sister/brother
