<P> Though various Indo - Aryan and Dravidian languages may seem mutually exclusive when first heard, there is a much deeper underlying influence that both language families have had on each other down to a linguistic science . There is proof of the intermixing of Dravidian and Indo - Aryan languages through the pockets of Dravidian - based languages on remote areas of Pakistan, and interspersed areas of North India . In addition, there is a whole science regarding the tonal and cultural expression within the languages that are quite standard across India . Languages may have different vocabulary, but various hand and tonal gestures within two unrelated languages can still be common due to cultural amalgamations between invading people and the natives over time; in this case, the Indo - Aryan peoples and the native Dravidian people . </P> <P> Prior to Independence, in British India, English was the sole language used for administrative purposes as well as for higher education purposes . </P> <P> In 1946, the issue of national language was a bitterly contested subject in the proceedings of the Constituent Assembly of India, specifically what should be the language in which the Constitution of India is written and the language spoken during the proceedings of Parliament and thus deserving of the epithet "national". Members belonging to the northern parts of India insisted that the Constitution be drafted in Hindi with the unofficial translation in English . This was not agreed to by the drafting Committee on the grounds that English was much better to craft the nuanced prose on constitutional subjects . The efforts to make Hindi the pre-eminent language were bitterly resisted by the members from those parts of India where Hindi was not spoken natively . Eventually, a compromise was reached with Hindi in Devanagari script to be the official language of the union but for "fifteen years from the commencement of the Constitution, the English Language shall continue to be used for all the official purposes of the Union for which it was being used immediately before such commencement". </P> <P> Article 343 (1) of the Constitution of India states "The Official Language of the Union government shall be Hindi in Devanagari script ." Unless Parliament decided otherwise, the use of English for official purposes was to cease 15 years after the constitution came into effect, i.e. on 26 January 1965 . </P>
