Arebica or Arabica (عَرَبٖىڄا) was a Bosniak variant of the Perso-Arabic script used to write the Bosnian language (بۉسانسقٖى يەزٖىق).[1] 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.
