step-siblings

Parents' spouses' children

Step-siblings are the children of one's stepparent from a previous relationship—not related by blood, but connected through a parent's marriage or partnership.

Unlike half-siblings, step-siblings share no biological parent: My step-siblings and I didn't meet until we were teenagers.

The relationship exists only through the union of their respective parents.
