What is "arebica"

Arebica or Arabica was a Bosniak variant of the Perso-Arabic script used to write the Bosnian language . It was used mainly between the 15th and 19th centuries and is frequently categorized as part of Aljamiado literature. Before World War I there were unsuccessful efforts by Bosnian Muslims to adopt Arebica as the third official alphabet of Bosnia alongside Latin and Cyrillic.

Apart from literature, Arabica was used in religious schools and administration, though in much less use than other scripts.
