Stepchild

Offspring of one's spouse, but not one's own offspring

A stepchild is the offspring of one's spouse, but not one's own offspring, either biologically or through adoption. Stepchildren can come into a family in a variety of ways. A stepchild may be the child of one's spouse from a previous relationship, or alternatively, be the result of an adoption, in which case the child would have no biological relationship with either parent.
