The Mon–Burmese script (မွန်မြန်မာအက္ခရာ)( ) (also called the Mon script, Old Mon script and Burmese script) is an abugida that derives from the Pallava Grantha script of southern India and later of Southeast Asia. It is the basis of the alphabets used for modern Burmese, Mon, Shan, Rakhine, Jingpho and Karen. History The Old Mon language might have been written in at least two scripts. The Old Mon script of Dvaravati (present-day central Thailand), derived from Grantha (Pallava), has conjecturally been dated to the 6th to 8th centuries AD. The second Old Mon script was used in what is now Lower Burma (Lower Myanmar), and is believed to have been derived from Kadamba or Grantha. According to mainstream colonial period scholarship, the Dvaravati script was the parent of Burma Mon, which in turn was the parent of the Old Burmese script, and the Old Mon script of Haripunjaya (present-day northern Thailand). However, according to a minority view, the Burma Mon script was derived from the Old Burmese script and has no relation to the Dvaravati Mon script, based on the claim that there is a four century gap between the first appearance of the Burma Mon script and the last appearance of the Dvaravati Mon script. According to the then prevailing mainstream scholarship, Mon inscriptions from the Dvaravati period appeared in present-day northern Thailand and Laos. Such a distribution, in tandem with archaeological evidence of Mon presence and inscriptions in lower Burma, suggests a contiguous Mon cultural space in lower Burma and Thailand. In addition, there are specifically Mon features in Burmese that were carried over from the earliest Mon inscriptions. For instance, the vowel letter အ has been used in Mon as a zero-consonant letter to indicate words that begin with a glottal stop. This feature was first attested in Burmese in the 12th century, and after the 15th century, became default practice for writing native words beginning with a glottal stop. In contrast to Burmese, Mon only uses the zero-consonant letter for syllables which cannot be notated by a vowel letter. Although Mon of the Dvaravati inscriptions differ from Mon inscriptions of the early second millennium, orthographical conventions connect it to the Mon of the Dvaravati inscriptions and set it apart from other scripts used in the region. Given that Burmese is first attested during the Pagan era, the continuity of orthographical conventions in Mon inscriptions, and the
