Jacoub is of Arabic origin, meaning "supplanter". It is derived from the Arabic name Ya'coub, which means "he will protect" or "may God protect". Jacoub is often associated with Jacob from the Bible, who was the father of the twelve tribes of Israel. The name gained popularity in Scandinavia during the Middle Ages due to the influence of Saint Jacobi, who was believed to have brought Christianity to Sweden and Denmark. Today, Jacoub is still a unique and distinctive name, often used within Muslim communities and occasionally found in other parts of the world as well.
"Jacoub is quite rare, with just five babies named Jacoub born each year on average over the past decade."
