stepsibling

Blended family member

A stepsibling is the child of one's stepparent from a previous relationship—not biologically related, but connected through a parent's marriage.

My dad remarried when I was twelve, so I grew up with two stepsiblings.

Unlike half-siblings, stepsiblings share no biological parent.
