Uyghur Arabic alphabet

Key characteristics

Unlike standard Arabic orthography, the Uyghur Arabic script represents vowel sounds with distinct letters rather than leaving short vowels mainly to diacritics. This feature makes vowel marking obligatory in most contexts, which reduces ambiguity when transcribing Turkic vowel harmony and syllable structure. The script is cursive: many letters change shape depending on their position within a word, and additional characters or modified forms are used to represent consonants and vowels not present in Arabic.

• Direction: written right to left.
• Vowel representation: explicit letters for vowels rather than optional diacritics; this supports clear pronunciation.
• Adaptations: extra letters, diacritic conventions and orthographic rules to render Turkic phonemes.

History and development

Uyghur has been written in a variety of scripts over many centuries, including Old Turkic runic forms and later alphabetic systems. Following the region's adoption of Islam and increased contact with Persian and Arabic culture, Arabic‑based writing systems became prominent. Over time, the Arabic script was adapted to fit Uyghur phonology. In the 20th century, various reforms and standardization efforts produced modern orthographic norms for education, publishing and administration. Alternative scripts — Latin and Cyrillic — have also been used in different periods and regions, so script practice varies by community and political context. For further context see Uyghur language and the Arabic alphabet.

Uses and examples

The Uyghur Arabic alphabet is widely used in books, newspapers, religious texts and everyday writing among Uyghur communities, especially in areas where it is the taught and official script. Its fully vowelled approach makes it suitable for orthographies that aim to represent spoken forms faithfully, including dictionaries and primers. When converting texts between scripts, transliteration must account for vowel letters and localized spelling rules.

Variants, standards and notable facts

Different publishing houses and regions may apply slightly different conventions for spelling and punctuation, but contemporary education systems have established standardized rules to promote literacy. Unicode includes the necessary characters and presentation forms so the script can be used in digital text. Linguistically notable is the contrast with Arabic: where Arabic writing often omits short vowels, Uyghur Arabic orthography requires explicit vowel notation, a design choice that reflects the language's phonological needs.
