Hindi is widely written, spoken and understood in North India and some other places in India. In 1997, a survey found that 45% of Indians can speak Hindi.

Hindi and Urdu were considered the same language but have evolved into separate dialects. However, to this day, both languages are mutually intelligible, meaning their speakers can understand each other without knowing the other language. Urdu, however, is written in the completely different Arabic alphabet.
Hindi developed from Sanskrit, the ancient language of India. Hindi started to develop in the 7th century as "Apabhramsha" and became stable by the 10th century. Some famous Hindi poets are Tulsidas and Kabir.
Dialects of Hindi include: Avadhi, Braj, Bhojpuri, Bundeli, Bagheli, Chhattisgarhi, Dogri and Marwari.
Hindi is also spoken with regional accents like Haryanvi and Rajasthani. Bombay Hindi is spreading because Bollywood films use it.
Hindi Diwas is an annual celebration on 14th September. It commemorates the law of 1949 that made Hindi the legal language of the Republic.
