Scripts :

            The present Assamese script is mainly the product of certain historical factors. The earliest specimen of Assamese script is provided by the Copper Plates and Assamese script was the corrupt form of the East Indian script of the Gupta period.78 This,however,differs from the script used during the Ahom period. From the thirteen century till the nineteenth century,the bark of the the aloe wood (Sachipat) was used. The  books written in early Assamese script has been divided by S.N. Sarma into three categories Gargayan,Bamuniya,Kayheli or Lahkari.
    Assamese script which is currently in use differs widely from its earlier specimen. The missionaries,who published several books in the nineteenth century from Bengal,used the same script for the both Bengali and Assamese books. The present Assamese script has several letters such as 'ra' and 'wa' which are absent in Bengali script.
    The Bodo language is said to have no inherited script. Earlier,there were a kind of Deodhai script among the Kacharis (Bodo)and Dimasa. Bishnu Prasad Rabha,the noted artist of Assam gathered a few specimen of Deodhai alphabet from Dimapur area. At present,the Bodo make use of the Assamese alphabet and the Roman alphabet as modified to suit their needs. Since 1963,the Bodo language has been introduced as the medium of instruction in the Bodo predominant Primary schools of Kokrajhar district.                                          Subsequently,Bodo medium of instruction was introduced first in the Secondary Schools of Kokrajhar with effect from Sept.,1968. It was now gone upto degree level. Davanagri script is now being used for the Bodo language with effect from April,1975. The Bodo language has since been declared as an associate official language by an ordinance issued on 28th Dec.,1984.
