Hindi vs Urdu: what's actually different

Spoken casually, Hindi and Urdu are close enough that a Hindi speaker and an Urdu speaker can chat for an hour and never notice a barrier. The grammar is the same, the everyday words are mostly the same, and the sounds nearly are. The real differences are in three places: the writing systems (Hindi uses Devanagari, Urdu uses a Perso-Arabic script), the formal and literary vocabulary (Hindi reaches for Sanskrit, Urdu reaches for Persian and Arabic), and a few sounds that Urdu keeps distinct and many Hindi speakers merge. If you are learning to talk to a family, the language you need is the shared middle, and it is the same language either way.

I'm Akhil. I grew up speaking Hindi, and the vocabulary I use at home is full of words that a textbook would file under Urdu. That is normal. It is also confusing for a learner who has been told these are two separate languages and now cannot tell which one the family is speaking. This post is the practical version of the answer: what is actually different, what is not, and which words to learn so you sound like the people around you rather than like a news bulletin.

One spoken language, two written standards

Linguists often describe Hindi and Urdu as two standardised forms of a single spoken language, historically called Hindustani, the everyday speech of the north Indian plains. Speakers, schools and governments treat them as two languages, and they have been developed as two for well over a century, with different scripts, different dictionaries and different literary traditions. Both descriptions are true in different senses, and the split has history and politics attached that this post is not going to rule on. What matters for you is the practical picture, and it looks like this.

The last row is the one that matters for anyone learning through Hinglish. The moment you take away the script, which is what happens in every WhatsApp group on the planet, the two languages collapse into one. "Kya kar rahe ho?" (what are you doing?) is the same sentence in Delhi, Lahore, Leicester and New Jersey.

The script is the biggest difference, and you can skip it

Hindi is written in Devanagari, the script it shares with Sanskrit and Marathi, running left to right with a line along the top of the letters. Urdu is written in a version of the Perso-Arabic script, usually in the Nastaliq style, running right to left. A Hindi reader cannot read Urdu and an Urdu reader cannot read Hindi, and this, more than anything spoken, is what makes them feel like different languages. Two people who chat freely at a dinner may be unable to read each other's shopping lists.

For a learner whose goal is conversation, this is good news. You do not need either script to speak. Romanised Hindi, the roman-letter spelling people use to text, is how Hinglish works, and it is script-neutral by definition. Learn the spoken language first and choose a script later, if you ever need one. I make the case for that order in how to learn Hinglish, and it applies whether the family you are joining calls its language Hindi or Urdu.

The vocabulary: where the two pull apart, and where everyday speech ignores the split

When Hindi needs a formal, technical or literary word, it tends to build one from Sanskrit. When Urdu needs one, it tends to borrow from Persian or Arabic. So a Hindi news broadcast and an Urdu news broadcast can sound quite different, while two friends from the same two cities sound the same. The table below shows the pairs. Read the middle column carefully, because in most Indian homes the "Urdu-leaning" word is simply the word people say.

Look at the right-hand column again. Kitaab, sawaal, waqt, dost, zindagi, intezaar, shukriya, maaf: every one of these is a Persian or Arabic loan, and every one of them is ordinary spoken Hindi. You will rarely hear "pustak" said out loud in a kitchen. The Sanskrit column is what you will see on a government sign, hear on a formal news programme, or read in a school textbook. It is real Hindi, and it is also not what a family says over dinner. If you learn from the right-hand column, you will be understood in a Hindu household in Delhi and a Muslim household in Karachi, and you will sound like a person in both. I went deeper on thank-you specifically in how to say thank you in Hindi, including why families rarely say dhanyavad to each other at all.

One honest caveat. Some families, and some regions, lean further one way than the table suggests. A Hindi-speaking family with strong ties to a temple, or a Sanskrit-medium education, may use more of the left column in daily life. An Urdu-speaking family may use a few Persian words for things where the table shows the shared word. Listen to the family you are actually joining and copy them. That is the whole method.

Bollywood speaks Urdu more than you were told

If you have ever wondered why the Hindi you learned from films is full of "ishq" (love), "dil" (heart), "mohabbat" (love), "khwaab" (dream), "junoon" (obsession) and "zindagi" (life), the answer is that Hindi film dialogue and lyrics have drawn heavily on Urdu poetic vocabulary since the industry began. The songs especially are often closer to Urdu than to textbook Hindi. Nobody in the cinema is confused by this, because it is all one spoken language to the audience. It does mean that a learner who arrives with film vocabulary and then opens a Hindi grammar book can feel like they have been studying the wrong thing. You have not. You have been learning the register people fall in love in, which is a perfectly good place to start.

The sounds: five letters Urdu keeps and Hindi often lets go

Urdu, because of its Persian and Arabic vocabulary, has a handful of sounds that Hindi historically did not, and its script has letters for them. Hindi marks them with a dot under an existing letter, and in everyday speech many Hindi speakers simply do not make the distinction.

• z as in "zindagi" (life) and "zaroor" (definitely). In parts of north India you will hear "jindagi" and "jaroor". Both are understood everywhere.
• f as in "faida" (benefit) and "saaf" (clean). Some Hindi speakers say "phaida" and "saaph", with a puff of air instead of a true f.
• q as in "qaum" (community). Deep in the throat in careful Urdu; most Hindi speakers say a plain "k", "kaum".
• kh (the throaty one, as in Scottish "loch") as in "khaas" (special). In Hindi speech this often becomes the ordinary aspirated "kh" of "khaana" (food), and again everyone understands.
• gh (the throaty one) as in "ghazal" (a poetic form). Most Hindi speakers say it with the plain "gh" of "ghar" (house).

What should you do about this? If the family you are joining is Urdu-speaking, it is worth making the true "z" and "f", because they will notice and appreciate it. If the family is Hindi-speaking, match whatever they do; a careful Urdu "q" in a Delhi kitchen sounds like you have been watching too many period dramas. Either way, these five sounds matter far less than the two that trip every English speaker: the dental versus retroflex "t" and "d", and the aspirated pairs. Those are shared by Hindi and Urdu, and they are the ones a microphone should be correcting. I explain them in is Hindi hard to learn.

Grammar: nothing to relearn

This section is short because there is almost nothing in it. Hindi and Urdu share their grammar to the point where a grammar written for one serves the other. The verb goes last: "main chai peeta hoon" (I drink tea, said by a man) and "main chai peeti hoon" (said by a woman) are the same sentence in both. Postpositions follow the noun: "ghar mein" (in the house). Nouns have two genders. "Aap", "tum" and "tu" are the three levels of "you", with the same rules about who gets which. Numbers are identical, and identically irregular; the table in Hindi numbers 1 to 100 serves an Urdu learner just as well.

There are small tendencies at the edges. Urdu speakers use "aur" and "lekin" (and, but) just as Hindi speakers do, but formal Urdu may prefer "magar" (but), and a few Persian constructions show up in careful Urdu that Hindi would express differently. In conversation these are invisible. If you learn the grammar once, you have learned it for both.

Greetings: this is about community, not vocabulary

The one place a learner can genuinely put a foot wrong is the greeting, and it is not really a Hindi-versus-Urdu question. It is a question of which family you are walking into. "Namaste" and "namaskar" are the greetings of most Hindu households, said with palms together. "Assalamu alaikum" (peace be upon you) and the reply "wa alaikum assalam" are the greetings of most Muslim households, whether they call their language Urdu or Hindi. "Aadaab", with the hand raised toward the face, is an older, courtly greeting still used in some Urdu-speaking families. Plenty of people from every background just say "hello" or "hi", and among younger people that is the most common greeting of all.

My advice is the same as it is for the vocabulary: use what the family uses. Say what your partner's parents say when they answer the door. If you are not sure, "hello" with a warm smile is never wrong, and asking "what do you say when you greet your grandmother?" is a lovely question that people are happy to answer. I covered the wider set of greetings, and when each one fits, in Hindi greetings beyond namaste.

So which one should you learn?

If you are learning for a person, learn their family's language and call it what they call it. A Pakistani family, or an Urdu-speaking Indian family, will call it Urdu; learn the true "z" and "f", learn "assalamu alaikum" and "shukriya", and know that the grammar and most of the words you learn will be identical to Hindi. A Hindi-speaking family will call it Hindi; learn "namaste", use the right-hand column of the vocabulary table, and know that half of it came from Persian and nobody minds. In both cases, the spoken language you need for a dinner table is the shared one, and you will learn it in romanised form, where the difference nearly vanishes.

If you are learning for the languages themselves, or for reading, then the choice is real and it is mostly about script and literature. Devanagari opens Hindi books, newspapers and Sanskrit-derived vocabulary. The Urdu script opens a poetic tradition that a lot of people think is one of the most beautiful in the world. Those are both fine reasons, and they are both a different project from learning to speak, which is the project we build for.

How we handle this in the app

Hinglish Vinglish teaches spoken, romanised Hindi, built around real situations with a family: meeting the parents, the dinner table, the group chat, travel. Because it is voice-first and romanised, the vocabulary it teaches is the shared middle from the table above, the words people actually say, rather than the Sanskrit register of a textbook. You say every phrase into the microphone, and Ellie, the elephant who coaches you, scores how close you sound to a native speaker and tells you the one thing to fix. It does not teach either script, and it is not an Urdu course; if your goal is to read Urdu poetry, a script-first course or a tutor will serve you better. For talking to a family in either language, it is a good place to start. Free to start, one-time unlock, no subscription, on iOS and Android.

FAQ

Can Hindi and Urdu speakers understand each other?

In everyday conversation, yes, easily. The grammar is shared and most common words are the same. Understanding drops when either side switches to a formal register, because formal Hindi draws on Sanskrit and formal Urdu on Persian and Arabic, and those vocabularies do not overlap.

Is Urdu just Hindi in a different script?

For casual speech, that is close to true. For formal writing, poetry, news and religion, the vocabularies diverge enough that the two feel like different languages. Both statements are accurate; they describe different registers of the same spoken base.

Which is easier to learn, Hindi or Urdu?

Spoken, they are the same difficulty, because they are the same spoken language. Written, most English speakers find Devanagari quicker to pick up than the Perso-Arabic script, because it runs left to right and writes every vowel. If you are not learning to read, the question does not arise.

If I learn Hindi, will I understand my Pakistani in-laws?

Chances are yes, in ordinary conversation. Learn the greeting they use, make the true "z" and "f" sounds, and favour the everyday vocabulary (shukriya, kitaab, waqt, dost) over the Sanskrit register. The rest of what you learn carries straight across.

Why does Bollywood Hindi sound like Urdu?

Because film dialogue and especially song lyrics have used Urdu poetic vocabulary since the early days of the industry. Ishq, dil, mohabbat, khwaab and zindagi are all Persian or Arabic loans. To the audience it is all one language, and for a learner it is a fine place to start.

Should I say shukriya or dhanyavad?

Shukriya, in almost every real situation, and "thanks" is at least as common. Dhanyavad is correct and formal, and families rarely use it with each other. Match the people around you.
