Jusuf
Yes. Jusuf is a Bosnian orthographic and phonetic variant of Yusuf, the prophet Joseph in the Quran. The meaning and identity correspond to Yusuf.
The prophet Yusuf appears throughout Surah 12. An early explicit mention of his story begins at verse 12:4 and continues through the chapter; the Bosnian spelling Jusuf is a regional rendering of that Quranic name.
The name derives from Hebrew Yosef meaning 'He will add' or 'God will increase.' Islamic onomastics commonly render this as 'God will increase' in meaning.
Jusuf is regionally common among Bosnian Muslims and in areas influenced by Bosnian orthography, but globally the Yusuf/Yousuf spelling is more prevalent.
Yes. While regional, the name remains valid across Muslim communities, and parents may choose Jusuf to honor Bosnian heritage or a particular phonetic preference.
