Arab scholars like Shihab al-Umari and Ibn Khaldun used the name Othman, while Ibn Battuta, who visited the region during Orhan I's reign, called him Osmancık (also spelled Othmānjiq or Osmanjiq).[15] The suffix -cık (or -cuk), indicates the diminutive in Turkish, thus he was known by the name of Osmancik, which means "Osman the Little", in order to differentiate between him and the third Rashidun Caliph "Uthman the Great".[16
