Uyghur Arabic alphabet

[1] The first Perso-Arabic derived alphabet for Uyghur was developed in the 10th century, when Islam was introduced there.

[2] The pre-modification alphabet used Arabic diacritics (zabar, zer and pesh) to mark short vowels.

[4][5][6][full citation needed] Alternative Uyghur scripts then began emerging and collectively largely displaced Chagatai.

Between 1937 and 1954, the Perso-Arabic alphabet used to write Uyghur was modified by removing redundant letters and adding markings for vowels.

Below is an incomplete list of suffixed spellings and their vowel harmony alternatives.

MS Windows Uyghur keyboard layout. Note that vowels are composed of pairs of Arabic letters, starting by an alef with hamza , that must be entered separately on this keyboard before the actual vowel. In fact, the keyboard is based on the older Latin alphabet used for Uyghur New Script and does not allow entering all vowels correctly for the current Arabic alphabet.
