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.
