English edit

Etymology edit

1903, modern revival of Old English sibling (relative, a relation, kinsman), equivalent to sib +‎ -ling. Compare Middle English siblynges pl, sib, sibbe (relative; kinsman), German 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. For example, the OED has a 1903 citation in which "sibling" must be defined for those who don't know the intended meaning.[1]
