Sef is Dutch short form of Jozef, the Dutch, Slovak, and Albanian form of Joseph. Joseph derives from the Hebrew name Yosef, meaning "he will add" or "he will increase," from the root יָסַף (yasaf). In the Old Testament, Joseph is the eleventh son of Jacob and the first with Rachel, favored by his father but sold into slavery by his brothers, eventually rising to power in Egypt. In the New Testament, Saint Joseph is the husband of Mary, and Joseph of Arimathea also appears. Etymology and Historical Usage As a Dutch short form, Sef follows a common pattern of truncation in Dutch given names. Other such diminutives or short forms of Jozef include Jef, Joep, Joes, Joop, Joos, and Joost. In the Middle Ages, Joseph was primarily a Jewish name; after the late Middle Ages, veneration of Saint Joseph increased in Catholicism, spreading the name in Spain and Italy. In Protestant regions like the Netherlands, it became common after the Reformation. In Swedish, the name Sef appears as an abbreviation of the biblical book Sefanja (Zephaniah), though this is rare as a personal name. Cultural Significance Sef is part of a broad family of names across languages: Yousef in Persian, Youssef and Yousif in Arabic, Yousuf in Urdu, and Zef in Albanian. These reflect the profound influence of the biblical Joseph narrative in Judaism, Christianity, and Islam. In Islamic tradition, Yusuf is a prophet known for his beauty and integrity.
