In the pre historic times, human beings express their thoughts and feelings with the usage of signs and symbols, comprising of the whole system of language. Vocal languages are unseen, the ape-man only make some cranky noises to communicate with their fellow members. Although there were hardly any evidences found about the development of spoken languages, traces of writings dated back to more than five thousand years. Mountain caves bore the witness of the man`s skill of communication by scribbling down pictures and images. Interestingly, the trend was that with the evolution of mankind, their languages too underwent massive changes. Modern languages adopted the complex nature, each language differ from the other, both in its format and grammatical syntaxes.

As far as India is concerned, the origin of Indian languages too has an ennobling history. It has developed, keeping in pace with the development of various ethno- traditional groups that have thrived in every nook of the whole of Indian subcontinent. As early as 2000 BC, Indus valley residents migrated to Gangetic plains and to certain places in the western side, segregating two main languages, Indo- Aryan languages and Iranian groups. It needs no mentioning that Indian languages are a part of this Indo- Aryan family. In fact, Indian languages have got three major phases: old phase comprises of Vedic and classical Sanskrit; Middle phase developed from near about third century BC incorporating certain vernacular Sanskrit dialects, namely Prakrits. Pali was a major dialect. The third phase had started from tenth century AD. Modern languages include languages of north and central provinces of the subcontinent of India.

Preliminary form of Sanskrit, namely the Vedic Sanskrit, is illustrious example that enriches the path of the origin of Indian languages. All the Vedic literature were written in this language which dated back as early as fifteen hundred BC to almost two hundred BC. Later, Classical Sanskrit developed near about five hundred BC, noted mainly for mythical and mechanical works. Even in the contemporary period, it is vividly studied in India. It is regarded as the most revered and erudite language.

The origin of Indian languages underwent an evolution with the starting of the illustrious second phase. The Prakrits evolved in several local varieties, which finally helped in the development of indigenous literatures. Pali has originated, as the sole language of the then Buddhist canonical writings. Still today, these writings are regarded as the ancient most Prakrit literature.

The Prakrits were widely used in every household of Indian subcontinent till the period of twelfth century. Even somewhat in between the tenth century, the contemporary Indo-Aryan vernaculars had started to gain popularity. The modern illuminates the whole story of the origin of Indian languages. Most of the Indian of the modern era is brightened due to the prevalence of numerous languages including thirty-five important languages. These are namely Marathi, Oriya, Punjabi, Hindi, Urdu, Bengali, Bihari, Gujarati, Kannada, Malayalam, Rajasthani, Tamil, and Telugu.

Two main languages embellish the origin of Indian languages. Hindi and Urdu are in fact somewhat diverse dialects of the similar language. Hindi vocabulary has been derived generally from Sanskrit language, and also Urdu incorporates several words of Persian and Arabic languages. Hindi writers follow the Devanagari script, and Urdu the script of Persian Arabic style.

Other major Indo - Aryan languages are Sinhalese which have their origin in India and now they have spread worldwide. Romani is another language, which had originated from Sanskrit, quite apt from its wealth of speech sound and grammar.

The origin of the Indian languages can also be traced to Brahmi. They have their origin from `North Semitic` family. Hindus of Maharashtra and Kashmir Valley have branched out Devanagari from Brahmi, which is mostly spoken. Apart from this they also use as Hindi, Sanskrit, and the Prakrits as main spoken languages. Also the denizens of Gujarat, West Bengal, Assam, and Orissa have developed their own writing systems which all are the derivations of Devanagari. Sindhis and Punjabis mostly use Persian Arabic script.

With the development of Dravidian languages, the whole origin of Indian languages has undergone an immense change. As per a survey, a rough estimate of 169 million populace of most parts of South India converse about twenty-three Dravidian languages. The four main Dravidian languages are popularized as official languages. These are Tamil (Tamil Nadu), Telugu ( Andhra Pradesh), Kannada ( Mysore), and Malayalam (Kerala). They have extensive fictional chronicles and are printed in the scripts of their own. Telugu is widely and its literature is quite enriched. Other Dravidian languages have only a handful of speakers. Maximum portion are popular verbally and no written documents have yet been found. . In nutshell, it is important to throw light upon the fact both the Dravidian languages and all the Indo Aryan languages complement each by borrowing words and grammatical tenets from each other and thus grow dignified.

Other Language Groups
Among other language groups that can be traced while studying the origin of Indian languages, mention of twelve and more Munda languages are worth to note. These languages mostly are widely spoken by the people that have resided in various parts of northeastern and Central India. Amongst them, Santali is the most significant. It is widely spoken by myriads of the people. What is even more interesting is that it is the only Munda language that had written records. Very similar to the Dravidian languages, the Munda languages have originated in the Indian subcontinent before the primitive people migrated from the southern parts of Indus valley.

According to the expert linguists of the country, the Munda languages have got the close relation to the Mon-Khmer languages, better known as the Austro-Asiatic family. A popular Mon-Khmer language, called Khasi, is also widely spoken in various provinces of Assam, state in India. Even in the fringes of Indian borders, quite a few `Sino-Tibetan languages` are also prevalent.

The history of India as an emblem of diversified culture ad tradition is richly exuberated due to the prevalence of various languages as developed through out the Indian panorama.
