Hindi shares with English and most other European languages the same ancestral roots. They evolved from a language thought to have been spoken in Central Asia around 5,000 BC, called by linguists the Indo-European parent language.

For this reason (and because of the 200-year influence of the British in India), many basic words in Hindi are the same as or similar to their equivalent in English. English words of Hindi origin include cot, loot, thug, chintz, bandanna, dungaree, rajali, pundit, coolie, tom-tom, and juggernaut

The primary source of Hindi is Sanskrit, one of the most ancient spoken and written languages in the world and one of the earliest members of the Indo-European language family. Like Sanskrit, Hindi is written in the Dev Nagari script, which is common to several other Indian languages as well. Much of the vocabulary of Hindi comes from Sanskrit, though Hindi also has a special relationship with Urdu. Their grammar and much of their vocabulary are virtually identical.

Hindi was originally a variety of Hindustani spoken in the area of New Delhi. Its development into a national language had its beginnings in the colonial period, when the British began to cultivate it as a standard among government officials. Later it was used for literary purposes and has since become the vehicle for some excellent prose and poetry.
