There seems to be a growing trend to move away from the term “stepfamily”
I actually found the following statement quite good.
Stepfamilies are increasingly referred to as blended families, by the media and others. Stepfamily researchers, family therapists, and the Stepfamily Association of America (SAA) view this term as inaccurate because it infers that members of a stepfamily blend into an entirely new family unit, losing their individuality and attachment to other outside family members. The term stepfamily is preferred because the derivation of the prefix “step-” originates from the Old English word “steop-” which means “bereave.” The term stepchild used to refer to orphans who lost their parents, and stepfather/stepmother used to refer to individuals who became parents to an orphan. Because other family types (biological, single-parent, foster, adoptive) are defined by the parent-child relationship, the SAA believes that the term stepfamily more accurately reflects that relationship and is consistent with other family definitions. Viewing the stepfamily as a blended family can lead to unrealistic expectations, confused and conflicted children, difficult adjustment, and in many cases, failure of the marriage and family.
