Sanjaki is a South Slavic language that is spoken in Sanjak. It is mutually intelligible with Serbian; in fact, during the time of the CSDS, Serbian and Sanjaki were called the Serbo-Sanjaki language. Modern Serbia simply regards Sanjaki as a Serbian dialect.
During the time of the Ottoman Empire, it was written in the Arebica script. During the time of the CSDS, Latin was used. The system was derived from a Bohemian-influenced alphabet by a Slevan-Croatian named Gaj, who thought that the current Croatian script needed reforms but failed. He did succeed in giving the Sanjakis a Latin-based script. When the Islamic Republic of Sanjak seceded from the CSDS, the Arebica script was reinstated, thought Latin remained official, such as in the logo of Sanjak Railways.
Sanjaki is used in Sanjak and in Dalmatia, especially those in the border, where it was usually called as 'Bosniak', not to be confused for the Dalmatian Muslim dialect. Sanjaki borrowed many Arabic and Turkish words; in the CSDS time, they were systematically purged. These loanwords were later reinstated during the time of the Islamic Republic.
