You’re planning a trip to Tehran or maybe just settling a bet. You ask the obvious question: what language do they speak in Iran? If you said "Arabic," you're in good company, but you're also totally wrong.
Honestly, it’s the most common mistake Westerners make. Iran isn't an Arab country, and while they use a script that looks a lot like Arabic, the language itself is worlds apart. Think of it like English and French—they share an alphabet, but if you start speaking one to a speaker of the other, you’re gonna get some blank stares.
The Official Word: Persian vs. Farsi
The official language of Iran is Persian. Now, you’ve probably heard it called Farsi. Is there a difference? Not really. "Farsi" is just the local name for the language, while "Persian" is what we’ve called it in English for centuries. It’s like calling the language of Germany "German" instead of "Deutsch."
Actually, there’s a bit of a movement among Iranian scholars and the diaspora to stick with "Persian" when speaking English. Why? Because "Persian" carries the weight of history—think Cyrus the Great, Rumi’s poetry, and ancient empires. "Farsi" sounds a bit more like a technical term for a dialect. But look, if you’re on the ground in Isfahan and you call it Farsi, nobody’s going to be offended. They’ll just be happy you aren’t trying to speak Arabic to them.
A Quick History Lesson (I Promise it’s Short)
Persian is an Indo-European language. That means it’s actually more closely related to English, Spanish, and Greek than it is to Arabic.
- Old Persian: Used by the Achaemenid kings (550–330 BCE).
- Middle Persian: The tongue of the Sassanid Empire.
- Modern Persian: What you hear today.
The weird part? Modern Persian hasn’t changed that much in 1,000 years. An educated Iranian can read a poem from the 10th century and understand most of it. Can you imagine a modern New Yorker trying to read Beowulf without a translation? No way.
It’s Not Just Persian: The Linguistic Mosaic
While Persian is the glue that holds the country together, Iran is a massive, diverse place. Only about half the population speaks Persian as their first language. If you travel across the country, the sounds change fast.
The Azeri Powerhouse
In the northwest, near the borders with Azerbaijan and Turkey, you’ll hear Azeri (or Azerbaijani). It’s a Turkic language. Basically, if you speak Turkish, you can get the gist of an Azeri conversation. It’s the second most spoken language in Iran, used by millions in cities like Tabriz.
The Kurdish West
Head to the Zagros Mountains and you’ll find the Kurds. They speak Kurdish, which is actually a group of related dialects like Sorani and Kurmanji. Like Persian, it’s an Indo-European language, but it sounds distinct. It’s rugged, beautiful, and the people are incredibly proud of it.

The Caspian Connection
Up north, tucked between the Alborz Mountains and the Caspian Sea, life is different. It’s green, rainy, and the people speak Gilaki and Mazandarani. These languages are closely related to Persian but have their own unique flair. If you’re a Persian speaker from Tehran, you might catch 60% of what a local is saying in a village in Gilan, but the rest will sound like a bit of a mystery.
Luri and Balochi
In the southwest, the Lurs speak Luri, which is often considered a sister language to Persian. Then there’s Balochi in the far southeast—a desert region bordering Pakistan. Balochi is a bit of an outlier; it’s an ancient-sounding tongue that has preserved sounds lost in modern Persian.
The Arabic Influence (And Why It’s Confusing)
Okay, so I said they don't speak Arabic, but that’s a slight oversimplification.
- The Script: Persian uses the Arabic alphabet, plus four extra letters ($p$, $ch$, $zh$, and $g$) to cover sounds Arabic doesn't have.
- Vocabulary: About 40% of Persian vocabulary comes from Arabic. This happened after the Islamic conquest in the 7th century. It’s like how English is full of French words because of the Normans.
- The Minority: There is actually a native Arab population in the southwest (Khuzestan province) who speak a dialect of Arabic.
- Religion: Every Iranian student learns some Arabic in school because it’s the language of the Quran. But ask them to order a pizza in Arabic? Most would struggle.
Can You Get By With English?
If you're visiting as a tourist, you’re probably wondering if you need to spend six months on Duolingo.
Short answer: No.
Long answer: It depends on where you are.
In Tehran, Shiraz, or Isfahan, the younger generation is surprisingly good at English. Many people take private classes from a young age. You’ll find that people are dying to practice their English with you. Seriously, you might get "ambushed" by a group of students just wanting to say hello and ask where you’re from.
However, once you hit the rural areas or the traditional bazaars, English fades fast. That’s where a few Persian phrases go a long way.
Practical Tips for Your Trip
If you want to win hearts in Iran, don’t just rely on English. The locals appreciate effort more than perfection.

- Learn "Salam": It’s the universal "hello."
- The "Merci" Trick: Iranians use the French word merci for "thank you" just as much as they use the Persian moteshakeram. It’s way easier to remember.
- The Power of "Khahesh Mikonam": This means "you're welcome" or "please." It’s the lubricant of Iranian social life.
- Tarof is Real: Iran has a complex system of etiquette called Tarof. Someone might offer you something for free—they don’t mean it. You’re supposed to decline a few times before accepting. It’s a linguistic dance.
Actionable Next Steps
If you're actually heading to Iran or just want to dive deeper, here is what you should do:
- Download a Persian Keyboard: Start getting used to the look of the script. Even if you can't read it, seeing the letters helps.
- Use the "Chai" Test: In almost any language in Iran—be it Azeri, Kurdish, or Persian—the word for tea is Chai. If you’re ever lost or overwhelmed, find a tea house, say "Chai," and everything will start to feel manageable.
- Focus on Phonetic Persian: Don't worry about the script yet. Use apps like Pimsleur or Mondly that focus on the sounds.
- Get a VPN: If you’re traveling there, you’ll need one to access most of the apps you use for translation or communication anyway.
Iran is a linguistic treasure trove. It’s not just one language; it’s a history of empires, mountain tribes, and Caspian poets all wrapped into one modern nation. Just don't call it Arabic.
