Jakub is a masculine given name common in Central and Eastern Europe. It is the Polish, Czech, and Slovak form of Jacob (and by extension James), with the same biblical origins. Etymology The name Jakub derives from the Latin Iacob, which comes from the Greek Ἰακώβ (Iakob), ultimately from the Hebrew יַעֲקֹב (Yaʿaqov). In the Old Testament, Jacob (later renamed Israel) was the son of Isaac and Rebecca and the father of the twelve tribal founders. His name is traditionally explained as meaning "holder of the heel" or "supplanter", because he grasped his twin brother Esau's heel at birth and later cleverly acquired his birthright and blessing (see Genesis 27:36). An alternative theory suggests the name may derive from יַעֲקֹבְאֵל (Yaʿaqovʾel) meaning "may God protect". Usage in Czech, Polish, and Slovak In Czech, Jakub is used exclusively for the New Testament apostles (James the Great and James the Less), while the Old Testament patriarch is referred to as Jákob. In Polish and Slovak, Jakub serves for both the patriarch and the apostles, unifying the biblical references under one form. A common diminutive for Jakub in Polish is Kuba. Notable Bearers Several notable individuals have borne the name Jakub, including: Jakub Arbes (1840–1914), a Czech writer known for his novels and journalistic work.
