Çağatay Türkçesi: Hüseyin Baykara ve Ali Şir Nevâyî

Chagatay Turkic is the name of the second period of the North-East Turkic. It starts in the beginning of the 15th century and lasts till the beginning of the 20th century. All the northern and eastern Muslim Turks dwelling in the east and north of the Caspian Sea, the Black Sea and Iran used the same written language from 15th century to the 20th century. The name of this written language is Chagatay Turkic. Chagatay Turkic is divided into three periods: Pre-Classical Period (The beginning of the 15 century-1465), Classical Period (1465-1600) and Post-Classical Period (1600-the beginning of the 20th century). Chagatay (Çağatay) is one of the sons of Chingis. The term comes from Chingis' second son, Chagatay. The word Chagatay used to mean the family of Chagatay and state that was founded by this family. However, later on, it came to mean the Turks and the Turkicizedpeoples living on the lands under the sovereignty of Chagatay family. During the reign of Timur, the term was used to designate all the peoples of the empire. Though the Chagatay period is mostly named as “Türkçe (Turkish)”, “Türki (Turkic)”, “Türktili (Turkish language), Ali Şir Nevayi, in his Mecalis'ünNefâisusedtheterm“Çagatay Lafzı (Chagataylangauge)”. The very first name that is associated with Chagatay Turkic is Ali Şir Nevayi. He is not only the biggest representative of Chagatay Turkic but also one of the most important names of all Turkicliterature. Hüseyin Baykara is one of the biggest factors that helped Ali Şir Nevayi reach his position. First of all, Hüseyin Baykara and Ali Şir Nevayi were very close friends since their childhood. Though Ali Şir Nevayi served the sultan with several titles, he was the closest friend of the sultan that he trusted very much. It is, as a result of this friendship, possible to see Baykara in Ali Şir Nevayi's almost all works. Most of the time, Ali Şir Nevayi praises the sultan, Hüseyin Baykara; however, this is not to gain something from the sultan. He expresses his sincere feelings. Likewise, the plac of Ali Şir Nevayi in the works of Hüseyin Baykara is distinct. In this article, the contributions of two close friends to Turkish have been studied.
