Jef is a Dutch masculine given name, primarily used in Belgium. It is a short form of Jozef, the Dutch and Slovak form of Joseph. Like many Dutch diminutives ending in -f, Jef originated as a casual, affectionate variant before becoming an established given name in its own right.Etymology and OriginThe name Joseph derives from the Hebrew יוֹסֵף (Yosef), meaning "he will add" or "God shall add," from the root yasaf ("to add, to increase"). In the Old Testament, Joseph is the eleventh son of Jacob and Rachel, who was sold into slavery by his brothers but later became a powerful advisor to the Pharaoh. In the New Testament, Saint Joseph is the husband of Mary. The name spread widely across Europe through Christian veneration, with many vernacular forms emerging. In Dutch-speaking regions, Jozef gave rise to several shortened forms including Joep, Joes, Joop, Joos, Joost, Jos, and Jef.Cultural SignificanceJef is particularly common in Flanders (Dutch-speaking Belgium) and has been borne by numerous notable figures. Artists include the painter Jef Dutilleux (1876–1960) and the musician Jef Denyn (1862–1941), a renowned carillon player. Sports figures include footballer Jef Delen (born 1976) and cyclist Jef Demuysere (1907–1969). In entertainment, Jef is the name of a character in the Dutch webcomic Jef by cartoonist Philippe Bialé. The name also appears in film and acting, as with Belgian director Jef Bruyninckx or Filipino actress Jef Gaitan. Despite its association with Jef François, a Belgian Nazi collaborator, the name remains widely used and is not stigmatized.Meaning: "He will add" (from Hebrew Yosef)Origin: Dutch short form of JozefType: Diminutive / given nameUsage regions: Dutch-speaking countries (esp.
