👉 The term "unsistered" is a phrase that can be used to describe someone who has not been adopted or is not related to another person. It implies that they are still considered part of their own family, but have not been officially recognized as such by their biological parents. In the context of adoption, unsistered children are often referred to as "non-adoption" children, as they may be orphaned or without a legal guardian who is responsible for their care and well-being.
