India has a diverse list of spoken languages among different groups of people. At least 30 different languages and around 2000 dialects have been identified. The Constitution of India has stipulated the usage of Hindi and English to be the two languages of official communication for the national government. Additionally, it classifies a set of 22 scheduled languages which are languages that can be officially adopted by different states for administrative purposes, and also as a medium of communication between the national and the state governments, as also for examinations conducted for national government service.

As drafted, English ceased to exist as an official language (on par with Hindi) in 1965, after which it was intended to continue as an "associate additional official language" until such time that a duly appointed committee can decide on a full-scale transition to Hindi, based on a periodic review. However, due to protests from some states like Tamil Nadu where there is low Hindi penetration, the "twin language" system is still in vogue. Due to rapid industrialization, and a bustling multinational influence in the economy, English continues to be a popular and influential means of communication in the government and day-to-day business, and moves to replace it have effectively been shelved.
