Hindi language belongs to the Indo Aryan family which in turn is a sub group of Indo- European family of languages. It is one of the most widely spoken languages of the world. Scholars like Dr Jayanti Prasad Nautiyal put it at number  while others put it number 2 and at number 3. According the latest figures in the Census of India, 2001, there are 422,048,642 people who have declared Hindi as their mother tongue and first language. This excludes other languages which, traditionally have been part of Hindi such as Maithili 12,179,122 and other non schedule languages. Just opposite to the popular belief and a myth created by Western media, English is the mother tongue of only 226,449 people which is approximately 0.2 percent, not even half a percent.
Hindi is one of the 22 national languages and the Official Language of India. Majority of people in Uttar Pradesh, Madhya Pradesh, Bihar, Rajasthan, Chhattisgarh, Uttarakhand, Jharkhand, Himachal Pradesh, Delhi, Andaman & Nicobar speak Hindi while it is the second most spoken language in Gujrat, Maharashtra, Punjab and Chandigarh. Members of emigrant Indian communities all around the world use Hindi as a lingua franca. This is truly an international language as it has some or the other forms of recognition in Fiji, Mauritius, Guyana, Suriname and Nepal.
Most of us would not believe that the modern Indo- Aryan languages have a vast pool of literary creations among them. Some of these standardized literary languages are Assamese, Oriya, Nepali, Bengali, Marathi, Konkani, Punjabi, Sinhalese, Sindhi, Kashmiri and Gujrati. These are the direct descendents of Sanskrit which remained the most important vehicle of communication of classical Indian literature, scriptures and for that matter the civilization itself.
Some commonality of relation of these modern Indian languages to Sanskrit can be found in modern Roman languages such as French, Italian, Portuguese, Spanish, Romanian to Latin.
India is such a vast country and a saying is famous there. It says-कोस कोस पै बदले बानी, चार कोस पै पानी meaning that after each two miles you pass, you come across a new dialect while the taste of water changes every eight miles. In strict terms, there are  dialects that have been included in Hindi census figures of 2001.
The standardized Hindi is called khari boli खड़ी बोली which literally means ‘standing dialect’. This dialect of Hindi is spoken in areas surrounding Meerut in Uttar Pradesh, bordering Delhi. The dialect rose to be a language in today’s term through a complex journey of some 1200 years. In its current from, Hindi has its vocabulary from such diverse sources as Sanskrit, Arabic, Persian, Turkish, Portuguese and English but mostly from Sanskrit.
