The Sogdian alphabet was originally used for the Sogdian language, a language in the Iranian family used by the people of Sogdia. The alphabet is derived from Syriac, the descendant script of the Aramaic alphabet. The Sogdian alphabet is one of three scripts used to write the Sogdian language, the others being the Manichaean alphabet and the Syriac alphabet. It was used throughout Central Asia, from the edge of Iran in the west, to China in the east, from approximately 100–1200 A.D.

Like the writing systems from which it is descended, the Sogdian writing system can be described as an abjad, but it also displays tendencies towards an alphabet. The script consists of 17 consonants, many of which have alternative forms for initial, middle, and final position. As in the Aramaic alphabet, long vowels were commonly written with matres lectionis, the consonants aleph, yodh and waw. However, unlike Aramaic and most abjads, these consonant signs would also sometimes serve to express the short vowels (which could also sometimes be left unexpressed as in the parent systems). To disambiguate long vowels from short ones, an additional aleph could be written before the sign denoting the long vowel. The alphabet also includes several diacritics, which were used inconsistently. It is written from right to left, but by the time it had evolved into its child system, the Old Uyghur alphabet, it had been rotated 90 degrees, written vertically in columns from left to right. Voiced and voiceless fricatives are consistently not distinguished in the script.
