The Ahom script or Tai Ahom Script is an abugida that is used to write the Ahom language, a dormant Tai language undergoing revival spoken by the Ahom people till the late 18th-century, who established the Ahom kingdom and ruled the eastern part of the Brahmaputra valley between the 13th and the 18th centuries. The old Ahom language today survives in the numerous manuscripts written in this script currently in institutional and private possession.
