Sadb

Sadb is an Irish feminine name from the Old Irish period. It is probably derived from the Proto-Celtic root *swādu- meaning "sweet", making it cognate with the Sanskrit svādú-, Ancient Greek hēdýs, Latin suāvis, and English sweet. The name was common in medieval Ireland. In Irish mythology, Sadb was a woman transformed into a deer; she became the mother of Oisín, whose name means "little deer", by the legendary hero Fionn mac Cumhaill.

Etymology and History

The name Sadb is the Old Irish form of the later Irish name Sadhbh, which is sometimes anglicized as Sive. Its ultimate origin lies in the Proto-Celtic word *swādwā, meaning "sweet and lovely lady". This is reflected in the Gallic names Suadu-gena and Suadu-rix. Sadb thus belongs to a linguistic family of words for sweetness found across Indo-European languages.

Historical and Cultural Significance

Despite its mythological roots, the name Sadb was a genuine given name in medieval Ireland. The town of Cahersiveen in County Kerry derives its name from the Irish Cathair Saidhbhín, meaning "the little fortress of Sadhbh". In a different vein, the name was used by the Whiteboys, a secret agrarian organization in 18th-century Ireland. They referred to themselves as "Queen Sive Oultagh's children", where "Sive Oultagh" is an anglicization of Irish Sadhbh Amhaltach ("Ghostly Sally"), drawing on the tradition of personifying Ireland as a woman.
