2. Uighurs have a long history of using characters. Before the ninth century, ancient Turkic letters were widely used, mostly inscriptions. Uyghur language is a long-term and wide-ranging language. This script was widely used in Xinjiang and Central Asia from the 8th century to13rd century (in some areas until16th century). After the 1930s, the Uyghur language has undergone several improvements, the most recent being in 1983. Now there are 32 Arabic letters in Uyghur, which are written horizontally from right to left. Each letter has different forms according to its position at the beginning, middle and end of the word. Simplex in the alphabet generally appears after the unconnected letters at the end of words except for the independent forms of letters; The antecedent appears before the connectible letter; Chinese style appears between two connectible letters of a word; The final form appears after the connectible letter at the end of the word.
Some letters have only simple and final forms. The symbols carried by some letters not only serve as signs of independent form and prefix form, but also play a role in sound insulation.
