Rab

Rab is primarily known as a diminutive of the Hebrew name Rebecca. Rebecca itself is a biblical name, appearing in the Old Testament as the wife of Isaac and mother of Jacob and Esau. The name gained popularity in the English-speaking world after the Protestant Reformation. While 'Rab' is not a standalone name with a distinct etymology, its usage as a nickname for Rebecca has historical roots, particularly in Scottish and Northern English dialects where 'Rab' or 'Reb' might have been used informally.
