Etymology

The word "stepsister" is a transparent compound from Old English, combining the prefix stēop- with the noun sweostor (sister). The Old English stēop- carried the specific meaning of "bereaved" or "orphaned," originally describing the relationship created when a widowed parent remarried, often implying the stepchild had lost a parent. Over time, the term broadened to encompass any familial relationship formed through remarriage, regardless of bereavement. Thus, "stepsister" logically denotes a female sibling acquired through the legal union of one's parent with a new spouse who has children from a prior relationship.
