“The Chorasmian script was used between the 2nd century and 8th to 9th centuries CE primarily to write the Chorasmian language, an Eastern Iranian language. The script was derived from Imperial Aramaic and is related to Parthian, Inscriptional Pahlavi, Psalter Pahlavi, Book Pahlavi, and Old Sogdian. ” - The Unicode Standard, Version 15.0
