Is Farsi Indo-European? What Persian Shares With English

Here’s a party trick that works every time. Tell someone that the Farsi word for “mother” is مادر. mâdar. Then tell them “daughter” is دختر. dokhtar. Then “name” is نام. nâm. Watch their face change. “Wait. those sound like English words.”

They do. Because Persian and English are related. Not borrowed-words related, not neighbors-who-traded related. genetically related. They descend from the same ancestor language, spoken somewhere around the Central Asian steppe roughly 4,500 years ago. Is Farsi Indo-European? Yes. And the evidence is hiding in plain sight inside words you already know.

The Quick Answer

Persian (Farsi) is an Indo-European language. It belongs to the Indo-Iranian branch, making it a distant cousin of English, French, German, Russian, Hindi, Greek, and Latin. The shared ancestry is visible in dozens of basic vocabulary words. family terms, body parts, numbers. that have survived thousands of years of separate evolution.

Where Persian and English Come From

Every language in the Indo-European family traces back to a single ancestor. Proto-Indo-European (PIE), spoken by a community that probably lived north of the Black Sea or in the Central Asian steppe around 4500-2500 BCE. Nobody wrote PIE down. We know it existed because the languages that descended from it share patterns too systematic to be coincidence.

From PIE, branches split off. The Germanic branch gave us English, German, Dutch, and Swedish. The Romance branch (through Latin) gave us French, Spanish, Italian, and Portuguese. The Indo-Iranian branch split further into Iranian (Persian, Kurdish, Pashto) and Indo-Aryan (Hindi, Urdu, Bengali).

Persian and English haven’t shared a common ancestor for roughly 4,500 years. That’s an enormous gap. Most of the surface similarity has been worn away by time. But dig into the basic vocabulary. the words people almost never borrow from other languages. and the family resemblance is unmistakable.

The Cognate Party Trick: 40+ Words You Already Know

Cognates are words in two languages that share a common origin. Not borrowed words. inherited words, passed down independently from the same ancestor. These are the linguistic equivalent of DNA evidence.

Family Terms

Body Parts

Numbers

Look at the numbers. “Two” and do. “Three” and se. “Ten” and dah. These aren’t coincidences. They’re 4,500 years of slow, predictable sound changes applied to the same original words.

Nature and Basics

“Star” and setâre. “Mouse” and mush. “Bad” is literally bad in both languages. same word, same meaning, passed down separately for millennia.

Through Latin, Greek, and French

Some of these are true cognates (inherited from PIE). Others. like “paradise,” “bazaar,” and “pajama”. are Persian words that English borrowed. But both types demonstrate the deep connection between the two languages.

Grammar: Where They Agree and Diverge

The shared ancestry shows up in grammar too, though less obviously than in vocabulary.

Both languages have:

• Subject-verb agreement (verbs change based on who’s doing the action)
• The “to be” verb as a cornerstone. English “is” directly cognates with Persian است (ast)
• Comparative adjectives (English -er, Persian -تر. -tar)
• A present/past/future tense system

Where they diverge:

• Word order: English is SVO (I eat rice). Persian is SOV (من برنج می‌خورم. man berenj mikhoram. literally “I rice eat”).
• English has articles (the, a). Persian technically has an indefinite marker (یک or -ی) but no “the.”
• Persian has no grammatical gender. English barely has any either. so they actually agree here more than, say, Persian and French.
• Persian uses the ezafe to link nouns. a feature English lost entirely.

Sound and Pronunciation

The original PIE sound system evolved differently in each branch. Linguists have mapped these sound shifts precisely. they’re as predictable as chemical reactions.

The key pattern: PIE *p became *f in Germanic (English) but stayed *p in Iranian (Persian). That’s why “father” (f) corresponds to pedar (p). Why “foot” corresponds to pâ (پا, foot/leg). Why “fish” corresponds to a hypothetical *pis- in ancient Iranian forms. This is called Grimm’s Law. yes, the same Grimm brothers who collected fairy tales also figured out systematic sound shifts between Indo-European languages.

Shared sounds: Both languages have the sounds /b/, /d/, /m/, /n/, /s/, /z/, /t/, /k/, /g/. An English speaker won’t struggle with most Persian consonants.

Sounds unique to Persian: The guttural kh (خ), the uvular gh (غ/ق), and the glottal ‘ain (ع) don’t exist in English. These came from Persian’s contact with Arabic, not from Indo-European roots. See our guide to the 7 Persian sounds English doesn’t have.

Why Persian Doesn’t FEEL Indo-European

This is the real question. If Persian and English are related, why do they feel so utterly foreign to each other?

Three reasons.

The script. Persian uses a modified Arabic alphabet. The moment an English speaker sees Persian text, it looks “Middle Eastern,” not “European.” But the script is just clothing. Arabic script was adopted after the 7th-century Arab conquest. Before that, Persian was written in Pahlavi script. Before that, cuneiform. The script tells you nothing about the language’s DNA.

The Arabic vocabulary. Roughly 40-50% of written Persian vocabulary comes from Arabic loans. Arabic is Semitic, not Indo-European. So when you’re reading Persian, nearly half the words you encounter come from a completely different language family. The Indo-European core vocabulary. the family terms, numbers, body parts, basic verbs. gets buried under a layer of Arabic-origin words. For the full Arabic-Persian relationship, see Farsi vs Arabic.

The time gap. 4,500 years of separation is a lot. English went through Proto-Germanic, Old English, Middle English, and absorbed massive amounts of French and Latin. Persian went through Old Persian, Middle Persian (Pahlavi), and absorbed massive amounts of Arabic. Both languages changed so much that the shared foundation is invisible without training.

Strip away the Arabic script. Strip away the Arabic loanwords. Look at the oldest, most basic layer of Persian vocabulary. the words for mother, father, water, earth, stand, sit, two, three, new, name. and you’re looking at English’s long-lost sibling.

Can an English Speaker Learn Farsi Faster Because of This?

Slightly. but don’t overestimate it.

The cognates give you maybe 50-80 “free” vocabulary words that feel intuitive once you see the connection. The lack of grammatical gender in both languages means one less headache. The shared logic of comparative adjectives (-er / -tar) transfers naturally.

But the SOV word order, the Arabic-script writing system, the spoken/written register gap, and the massive Arabic vocabulary layer mean English speakers still face a Category III-IV language (per the FSI). The Indo-European connection is a nice head start on some core vocabulary. It’s not a shortcut.
