The main basis of today's Bengali language is Aryan language. The origin of the present language is through the millennial transformation and the fusion of the languages of the other three groups. Two and a half thousand or three thousand years ago, the Aryan people of the Europaid style entered India and began to have a rapid influence due to the prevalence of their language. Through them the language of Vedic or Rigveda first came to India. The Aryan language then spread from Punjab through northern India to Bihar, between 1000 and 600 BC. The complexity of the grammar of the Vedic language becomes somewhat simpler in general contact. At the same time, the spoken language also changes due to this. At this stage, there was a great difference between the western and eastern languages of the vast region under the Aryan language. The change came in the language of the East. The breakdown took place in the original Aryan language and the creation was in the Prakrit language. Later, this language got two distinct forms with a completely natural resemblance to the East of the West and the East of the East. The last name was given as Magadhi as it was said in Magadi. Some literary specimens of Magadhi Prakrit are found in later grammars of later Sanskrit plays, such as Mrichkatik and Barruchi. Over the next seven hundred years, Magadhi Prakrit gradually changed to a corruption of the Apabhramsa language. This corruption was turning into Bihari (Bhojpuri, Maithili, Magadhi), Bengali, Assamese and Oriya. In other words, the period of Bengali language begins in the next step in corruption. The new Bengali language appeared around the ninth and tenth centuries. Linguists call it the earliest period of Bengali language. After the Turkish conquest in 1203 AD, stability was naturally lost for a few days. Srikrishnakitana, the original Bengali epic poet Chandidas, written in 1350 AD, about one and a half years after the Charyapada period, put an end to this friendship. Thus began the middle period of the Bengali language. From the fifteenth to the eighteenth centuries, the Bengali language was the last period of the Middle Ages. At this time the social revolution of Chaitanyadev and the generosity and patronage of the independent sultans of Bengal brought a new tide in Bengali language and literature. Bengali poets created Padabali Kirtan, Dharmasahitya, Mangal Sahitya, Pranyopakhyan and Punthisahitya. The modern era of Bengali language started from the eighteenth century. However, in the nineteenth century, language and literature have gained a modern identity. Among the architects of modern Bengali language are Ishwar Chandra Vidyasagar, Michael Madhusudar Dutta, Bankim Chandra Chattapadhyay, Rabindranath Tagore, Kazi Nazrul Islam and others. Then the Bengali language genealogy is being read - a form of Vedic spoken language> spoken language of the eastern region> Magadhi Prakrit. Magadhi apabhrangsa> ancient Bengali (language of the Charyaps)> medieval Bengali> modern Bengali.
The main components of the Bengali language are the Sanskrit-derived Tatsam, Ardh-Tatsam and the derived Tadbhav words. And the original desi word which can be any kind of Austrik or Dravidian. From the point of view of language, since time immemorial, there were four distinct parts of the Bengali-speaking region: 1. Radha-suksha. 2. Barindra-Pundra, 3. Banga-samatata, 4. Kamarupa-pragjyotisha. The four regional languages on the basis of the different forms of Magadhi Prakrit and Apabhrangsa are Radhi Barindri, Bengali and Kamrupi, respectively. The language was prevalent in Rangpur, parts of Dinajpur and Jalpaiguri, Darjeeling, Cooch Behar, Dhubri etc. in India.
Bengali is the main language of the people of Gaibandha district. English is prevalent among the educated. A small number of non-Bengali resident speak Urdu. The Sawtals use their own Sawtali language. The Bengali language used in Gaibandha district is simple, meaningful, easy to pronounce, sublime and melodic. They contain many words, proverbs and songs that can be used in civilized society. And these contain various philosophies and thoughts. In some cases the illusion of illiterate authors remains, but their importance in the field of history, tradition and culture is significant.
