Union Home Minister Amit Shah today appealed on Hindi Diwas to unify India with the most widely spoken language of the country-Hindi. His tweet says it is "essential for India to have a language that worldwide marks its identity." While he said that Hindi is the language that can unify the nation, he also stressed that India is a country with many languages and dialects. Amit Shah tweeted on Hindi Diwas, which is celebrated on September 14 each year, marking the day when the Constituent Assembly of India embraced Hindi as India's official language. Hindi, written in the Devanagri script, is one of the country's 22 planned languages. However, Hindi is one of the two official languages of the Union Government, the other being English.
