If you’re planning a trip to Mumbai or trying to localise a business app for the Delhi market, you’ve probably asked yourself: what's the language of India? It sounds like a simple question. You’d expect a simple answer, like "French" for France or "Japanese" for Japan. But India doesn’t work like that. Honestly, India is more like a continent than a single country when it comes to how people talk.
There is no single "National Language" of India. None.
That usually surprises people. You might have heard that Hindi is the national language, but that's a common misconception that can actually get you into some heated debates in places like Chennai or Bengaluru. According to the Constitution of India, specifically Article 343, Hindi in Devanagari script is the "Official Language" of the Union. But English is also there as an "additional" official language. Then you have 22 scheduled languages. It's a lot.
The Hindi vs. English reality
Basically, the government uses Hindi and English to communicate. If you look at a bank note, you’ll see the denomination written in fifteen different languages on the back, plus Hindi and English on the front. This isn't just for decoration. It’s a necessity.
Hindi is spoken by about 44% of the population, according to the last census data. That’s a huge chunk, mostly across the "Hindi Belt" in the north—places like Uttar Pradesh, Bihar, and Madhya Pradesh. But if you head south to Karnataka or Tamil Nadu, Hindi might not help you much. In fact, in many southern states, English is the preferred lingua franca between people who speak different regional tongues.
English is the language of the elite, the courts, the tech industry, and higher education. It’s what connects a software engineer in Hyderabad with a client in Boston, or even a doctor in Kerala with a patient in Punjab. It’s a "link language." Without it, the country’s bureaucracy would probably grind to a halt.
The 22 Scheduled Languages (The Eighth Schedule)
The Indian Constitution has this thing called the Eighth Schedule. It’s a list of 22 languages that the government is obligated to develop and protect. These aren't just "dialects." They are ancient, distinct languages with their own scripts, literatures, and grammars.

Some of these are massive. Bengali, for instance, is the second most spoken language in India. If West Bengal were its own country, it would be one of the most populous linguistic blocks in the world. Then you have Telugu, Marathi, Tamil, and Urdu. Each of these has tens of millions of speakers.
- Bengali: Predominant in West Bengal and Tripura.
- Telugu: Spoken across Andhra Pradesh and Telangana.
- Marathi: The heartbeat of Maharashtra and Mumbai.
- Tamil: One of the oldest surviving classical languages in the world, spoken in Tamil Nadu.
- Gujarati: The language of commerce in Gujarat.
Then there are others like Sanskrit, which is rarely spoken as a first language but is the liturgical root of many Indian tongues, much like Latin in Europe. Or Santhali and Bodo, which represent the country's indigenous and tribal heritage.
Why people get it wrong
People often think what's the language of India is Hindi because Bollywood is so famous. If the movies are in Hindi, everyone must speak it, right? Not really. While Bollywood has definitely helped spread Hindi vocabulary to the corners of the country, many people in the South or the Northeast watch their own massive film industries—Tollywood (Telugu), Kollywood (Tamil), or Mollywood (Malayalam).
The linguistic divide is also geographic. Broadly speaking, the languages in the north belong to the Indo-Aryan family (related to European languages). The languages in the south are Dravidian. They are completely different. A native Hindi speaker might find it easier to learn a bit of Spanish than to learn the complex grammar and script of Kannada.
The "Mother Tongue" explosion
If you dig deeper into the 2011 Census (the most reliable comprehensive data we currently have, as newer counts have faced delays), the numbers are staggering. People reported over 19,500 languages or dialects as their mother tongues. After the government grouped them together based on linguistic similarities, they narrowed it down to 121 "major" languages.
Think about that. 121 languages spoken by at least 10,000 people each.

It’s not just about the words. It’s about identity. In 1956, India actually redrew its internal state borders based on language. That’s why the states exist in their current form. Andhra Pradesh was created for Telugu speakers, Kerala for Malayalam speakers, and so on. Language is a political third rail in India. Whenever the central government tries to push Hindi as the sole primary language, there are usually protests in the south. They see English as a "neutral" alternative that doesn't give northern speakers an unfair advantage in government jobs or exams.
Code-switching and "Hinglish"
In reality, most urban Indians are bilingual or even trilingual. A typical teenager in Delhi might speak Punjabi at home with their grandparents, Hindi with the local shopkeeper, and a mix of English and Hindi (Hinglish) with their friends.
Hinglish is fascinating. It’s not just slang; it’s a legitimate way of communicating that blends English grammar with Hindi vocabulary or vice versa. Brands like Pepsi and Coca-Cola have used Hinglish in their ad campaigns for decades because that's how people actually talk. "Yeh Dil Maange More" (This heart wants more) is perhaps the most famous example.
Practical advice for travelers and professionals
If you’re heading to India, don't stress about learning ten different scripts.
In big cities, English will get you almost everywhere. Most signs are in English and the local regional language. If you're in the North, learning a few Hindi phrases like "Kitna hua?" (How much?) or "Namaste" (a respectful greeting) goes a long way.
But if you’re in Chennai, "Namaste" isn't the local word—it's "Vanakkam." People will appreciate the effort if you use the local greeting instead of assuming they speak Hindi.

For business, English is the gold standard. However, if you are targeting rural markets, you absolutely must localise. A marketing campaign in Bihar needs to be in Hindi (and specifically a dialect like Bhojpuri if you want to be really effective), while a campaign in rural Karnataka must be in Kannada. There is no "one size fits all" strategy here.
What's the future?
Is English taking over? Sorta. Is Hindi expanding? Definitely.
Digital penetration is changing things. As more people in rural India get smartphones, the demand for content in regional languages is exploding. YouTube and Netflix are pouring money into regional content because they know the "next billion" users aren't looking for English content. They want stories in their mother tongue.
The question of what's the language of India doesn't have a singular answer because India is a pluralistic society. It’s a collection of linguistic identities held together by a shared history and a complex administrative framework.
Actionable Next Steps
If you're looking to engage with India, whether for travel or work, stop looking for one language. Instead:
- Identify the State: If your focus is Bangalore, learn the basics of Kannada. If it’s Kolkata, look at Bengali.
- Use English as the default for tech/business: Most professional environments operate entirely in English.
- Download a translation app with offline capabilities: Google Translate supports many Indian languages like Hindi, Bengali, Tamil, and Telugu.
- Recognize the script: Even if you can't speak it, learning to recognize the difference between the curvy scripts of the South and the "barred" script (Devanagari) of the North will help you orient yourself.
- Respect the local tongue: Never assume a person from the South or Northeast speaks Hindi. Ask "Do you speak English or Hindi?" or simply stick to English until they indicate otherwise.
