Etymology: The word "sib" descends from an Old English noun, "sibb," meaning kinship or peace between kin, and the root behind it is very old. Its ancestor reaches back to a Proto-Indo-European root meaning "one's own," the same idea that gave Latin "suus." That is a striking pairing: the notion of what belongs to you, your own people, sits behind a word now used almost only in technical genealogy and anthropology. The word survived in English as a sense of relationship and kinship, and it also meant peace or friendship between families. Germanic relatives follow the same pattern, with Dutch "sibbe," German "Sippe" (clan or tribe), and West Frisian "sibbe" all carrying the idea of family bonds. Over time English let the everyday sense fade while the old noun persisted in specialist use. In modern English the term is mainly found in anthropology and genetics, where a "sib" is a sibling, and "sibs" describes people sharing the same parents. Its usefulness lies in sounding neutral and precise, free of gendered terms such as "brother" or "sister."
