According to Grigor'ev, , or decrees of the Khans, were written in Mongol, then translated into the Cuman language. The existence of Arabic-Mongol and Persian-Mongol dictionaries dating from the middle of the 14th century and prepared for the use of the Egyptian Mamluk Sultanate suggests that there was a practical need for such works in the chancelleries handling correspondence with the Golden Horde. It is thus reasonable to conclude that letters received by the Mamluks – if not also written by them – must have been in Mongol.
