India is a country of unity in diversity with a confluence of multicultural languages and traditions. Among various scheduled tribes, Koda Adivasi is one. This tribe is a part of Mundari of Austrik language. The language of Koda Adivasi is ‘Koda Jagar’ and the written form of the Koda Language is known as ‘Nagchiki’ in their society. The founder of this language is Shree Dinesh Mudi( Mahukal Sapu Koda). Smt. Hasi Mudi, uncle Shree Naren Singh and grandfather Shree Hemal Mudi inspired Shree Dinesh Mudi to create and form letters of Koda Language. His wife Smt. Anima Mudi, brother Shree Chandramohon Singh ( Mastermosai), brother Shree Jisai Singh ( social activist) contributed to further explaining the letters of Koda Language. Besides, his brother Shree Sadhu Singh designed a software of this language. The author started writing Nagchiki in 2005 and the full form of this language as Adivasi Koda got published by him in 2012.

Mythical story of Nagchiki
In the mythical story of Koda Adivasi, king Samat Raghu Mudi or Koda old men and women left their only baby under a tree while digging in the fields with spade. The King, to get rid of the Hoons and also to save the baby, left it under the shadow of the trees and as the sunrays moved its directions from over the baby , the Panchanag raised its hood to give shadows and protection to the baby. Right after this , beside the sleeping baby, Munda old men and women came across the river to hunt or to collect woods ; afterwards the Mundas arranged to name the baby. Beside this story, another story goes like this that the orders were given by the Hoons to kill the Adivasi young boys. During this time in the Koda society , festivals of worship were performed in Chotanpur Sinbhum. More is heard that the Hoons came out for mass killing of the Koda youths with spears. More stories exist such as there were fights between the Koda and the Hoons with sharp weapons like spear, bow, arrows etc. At last the Kodas were defeated. The King Raghu along with his sister left Chotonagpur across the river. According to seaman Munda, the Koda Adivasi changed their titles from Koda and Mudi into Sing and they started living in the Munda community to save their lives from the attacks of Hoons. This is the brief story of social and mythical history and the mentions of Naga King Panchanag, trees, sun, road,bows, arrows, spade, dagger, social customs, worshipping festivals, marriagesm fruits, birth and death etc. are part of community history. From these spectacular depictions of the Koda Adivasi, the form and matter of Chiki and finally its titling is justified.

The Explaination of the name Chiki and its acknowledgement
Nag:- Nag refers to KORA caste belonging to the heritance of Nagabonshi and Adivasi Koda is for theancestors living in the native places i.e. Chtonagpur as is evident by the word ‘Nag’.
Chiki:- Chiki refers to letter or word. The sign of the Kada language is the initial pronunciation = ‘chi’ and ‘Kinha’( in Bengali it means the meaning). It is constructed by placing the initial word of the language.

Publicity of Koda language through Nagchiki
Kodas started writing in Nagchiki in 2005 and completed in 2012 and since then Nag Chiki letters and script were being displayed in meetings of Koda society. The only means to keep our language alive is to visit many villages and spread the message of importance of this Nagchiki. Many scholars and village heads advise me to find simple ways to learn Koda language along with Nag chiki so that they learn Nagchiki grammar and the usages of each letter. He took initiatives from people of all walks of life and began writing “Adivasi Koda Language”. Finally, after an untiring effort of one and a half years, with the sincere help of Shree Sadhu Sing , the 152 page book “Adivasi Koda Language” was completed and the Mission of keeping Koda Language alive with the help of Nagchiki is being accomplished.
