Nguồn gốc từ
First use appears c. 1903, a modern revival of Old English sibling (relative, a relation, kinsman), equivalent to sib + -ling. Compare siblynges, sib, sibbe (relative; kinsman), Sippe. The term apparently meant merely kin or relative until the 20th century when it was applied in a way that aided the study of genetics, which led to its specialized use.
