The earliest surviving Mongolian text may be the , a report on sports composed in Mongolian script on stone, which is most often dated at 1224 or 1225. The Mongolian-Armenian wordlist of 55 words compiled by Kirakos of Gandzak (13th century) is the first written record of Mongolian words. From the 13th to the 15th centuries, Mongolian language texts were written in four scripts (not counting some vocabulary written in Western scripts): Uyghur Mongolian (UM) script (an adaptation of the Uyghur alphabet), 'Phags-pa script (Ph) (used in decrees), Chinese (SM) ("The Secret History of the Mongols"), and Arabic (AM) (used in dictionaries). While they are the earliest texts available, these texts have come to be called "Middle Mongol" in scholarly practice. The documents in UM script show some distinct linguistic characteristics and are therefore often distinguished by terming their language "Preclassical Mongolian".
