step-

Non-blood family marker

Step- is a prefix attached to family relationship words to indicate a bond created through marriage rather than biology or adoption.

A stepmother or stepfather is the spouse of one's biological parent, and stepchildren are the children of one's spouse from a previous relationship.

Step-siblings share no blood relation but become family when their parents marry each other.

The prefix carries no inherent negative connotation, though fairy tales have given stepmothers an unfairly wicked reputation.
