Do Indians really speak a combination of English and Hindi?

Many languages are spoken in India, but only English and Hindi are official. A few Indians(e.g. Anglo-Indian railway workers) have English as their mother tongue. Most ambitious Indians learn at least some English to advance in their careers. Naturally, many Hindi speakers with just a little English will try to impress the totally ignorant by including a few English words or phrases when speaking Hindi. Snobs in England have been doing the same thing with French for generations: that is why modern English includes so many quite unnecessary French words ("modern", "includes" and "necessary" among them).

Millions of Indians do not or cannot speak Hindi. There are 18 official languages in India. Hindi and English are the most important official languages of India. India does not have a national language.

In cities of North, East and Westen India, YES.

In the South Indian cities they don't like to speak Hindi but are okay with English.
