Borjigin

Etymology
From. According to, in his , and later , in his Genealogy of the Turks, this name meant 'having eyes of the color اشهل (ašhal) ~ شهلا (šahlā)', i.e. 'dark blue eyes', which Genghis Khan and his brothers reputedly all had.

However, according to, "The etymology of the name Borjigin is uncertain. The unreliable interpretation given by Rašīd (borjigin = 'man with dark blue eyes') accounts, through a further misunderstanding, also for the imaginary grey (pmo., mo. boro), or cat's eyes of Činggis Qan, regularly ascribed to the conqueror by modern authors."
