What is the Difference Between Stepsister and Half-Sister?

The main difference between a stepsister and a half-sister lies in the way they are related. Here are the key distinctions:

• Stepsister: A stepsister is the daughter of one's stepmother or stepfather from a previous marriage. Step-siblings are related only by the marriage of their parents and do not share a common biological parent.
• Half-sister: A half-sister, on the other hand, is a sister with whom one shares only one biological parent in common. Half-siblings have one biological parent in common and do not share the other parent.

In summary, stepsisters are related by the marriage of their parents, while half-sisters share a common biological parent. There is no biological relation between step-siblings, as they do not share a common parent.
