Spoken vs Written Persian: 36 Everyday Differences

Spoken Persian is not a different language from written Persian, but it sounds different in regular, predictable ways. Tehrani speech turns ân into un (نان nân becomes نون nun), shortens verb stems (می‌گویم miguyam becomes می‌گم migam) and softens endings. Learn about ten rules and you can connect the two.

Persian speakers have two everyday registers. The written or “bookish” register, کتابی (ketâbi), is what you see in newspapers, textbooks, signs and the news. The spoken register, محاوره (mohâvere, “conversation”), is what you hear at home, in shops, in films and on the street. In Iran the spoken standard is based on the speech of Tehran. Linguists call this kind of split diglossia, and Persian has a strong version of it: a learner who only studies the written forms can read a newspaper but may struggle to follow a taxi driver.

The good news is that the gap is not random. Most spoken forms come from a handful of sound changes. Below you will find the rules, a table of 36 everyday pairs with transliteration, and practice blocks so you can test yourself.

Why spoken and written Persian sound different

Written Persian keeps older, fuller forms of words. Everyday speech has worn many of them down over time, much as English speakers say “gonna” for “going to,” but in Persian the changes are far more regular and affect almost every sentence. Persian researchers call these colloquial variants صورت‌های شکسته (surat-hâ-ye shekaste, “broken forms”). As a linguistics article published in a University of Guilan journal points out, they are not always shorter: خونه (khune) is the same length as خانه (khâne), and بهش (behesh) is actually longer than به او (be u).

Two points to keep in mind:

• Both registers use the same alphabet and almost the same vocabulary. The difference is mostly in pronunciation and in a few grammar endings.
• Persians often write the spoken form too: in text messages, social media, song lyrics, film subtitles and the dialogue of modern novels. So you will read می‌خوام as often as you hear it.

The 7 main sound changes from written to spoken Persian

1. ân and âm become un and um

When long â comes before n or m, Tehrani speech usually turns it into u: نان nân → نون nun (bread), آن ân → اون un (that), بادام bâdâm → بادوم bâdum (almond). The capital itself is تهرون Tehrun in casual speech. This rule is common but not universal. Learned and formal words keep ân: nobody says “Irun” for ایران (Irân), and انسان (ensân, human being) and امکان (emkân, possibility) stay as they are. When you are unsure, the written form is always understood.

2. ast (“is”) becomes -e or -s

The written verb است (ast) almost never appears in conversation. After a consonant it becomes -e: خوب است khub ast → خوبه khube (it’s good). After a vowel it shrinks to -s: کجاست kojâst → کجاس kojâs (where is it?).

3. The object marker râ becomes ro or o

The direct object marker را (râ) becomes -o after a consonant and ro after a vowel: کتاب را ketâb râ → کتابو ketâbo, این را in râ → اینو ino, خانه را khâne râ → خونه رو khune ro.

4. Verb endings: -ad becomes -e, -and becomes -an, -id becomes -in

Three personal endings change in speech. Third person singular -ad becomes -e (می‌خورد mikhorad → می‌خوره mikhore, he/she eats). Third person plural -and becomes -an (می‌خورند mikhorand → می‌خورن mikhoran). Second person plural -id becomes -in (می‌کنید mikonid → می‌کنین mikonin). The endings for “I,” “you” (singular) and “we” stay the same.

5. Short verb stems

A few very common verbs have shortened present stems in speech. These are worth memorizing as whole words, because they appear in nearly every conversation:

• رو (rav, go) → r: می‌روم miravam → می‌رم miram Listen
• گو (gu, say) → g: می‌گویم miguyam → می‌گم migam
• خواه (khâh, want) → khâ: می‌خواهم mikhâham → می‌خوام mikhâm Listen
• آ (â, come) → â with no y: می‌آیم mi-âyam → میام miyâm
• ده (deh, give) → d: می‌دهم midaham → می‌دم midam
• شو (shav, become) → sh: می‌شود mishavad → می‌شه mishe
• توان (tavân, can) → tun: می‌توانم mitavânam → می‌تونم mitunam

6. Pronouns become suffixes

Written Persian often uses the separate pronoun او (u, he/she) after a preposition. Speech prefers the attached suffix -esh: به او be u → بهش behesh (to him/her), از او az u → ازش azesh (from him/her), با او bâ u → باهاش bâhâsh (with him/her). Objects attach to the verb in the same way: او را دیدم u râ didam → دیدمش didamesh (I saw him/her). The same pattern works with other persons: بهم (beham, to me), بهت (behet, to you).

7. Small words that change shape

A group of high-frequency words have their own spoken forms: دیگر digar → دیگه dige, اگر agar → اگه age, یک yek → یه ye (a, one), چه che → چی chi (what), and the plural -hâ usually drops its h: آنها ânhâ → اونا unâ (they).

36 everyday differences: written vs spoken Persian table

The spoken forms below are standard Tehrani colloquial Persian, the variety you hear in most Iranian films and TV series.

Two more pairs are worth knowing even though they are word swaps rather than sound changes: بله (bale, yes) is the polite form, while آره (âre) is the casual one, and خداحافظ (khodâhâfez, goodbye) is usually said خدافظ (khodâfez) Listen.

Putting the rules together in a sentence

Real sentences usually combine several rules at once. Here is one simple example:

• Written: من نان را به او می‌دهم. (man nân râ be u midaham.)
• Spoken: من نونو بهش می‌دم. (man nuno behesh midam.) Listen
• Meaning: I give the bread to him/her.

Four changes happened: nân became nun, râ became -o, be u became behesh, and midaham became midam. Spoken Persian also tends to move a destination after the verb: written به خانه می‌روم (be khâne miravam) is usually said می‌رم خونه (miram khune), with the be dropped.

When to use written Persian and when to use spoken Persian

Notice that “polite” and “spoken” are not opposites. A shop assistant who calls you شما and says بفرمایید (befarmâyid, please, go ahead) is being polite, yet will still say می‌خواین (mikhâyn, do you want) rather than می‌خواهید (mikhâhid). Politeness lives in word choice and the plural “you,” while the colloquial sound changes stay.

How learners should study both registers

1. Learn the written form first as the “dictionary form.” Dictionaries, grammar books and verb tables list written forms. If you know می‌گویم, you can look it up; می‌گم may not be listed.
2. Learn the spoken form right next to it. Every time you learn a common verb, write both forms on the same flashcard, as in the cards above. Our list of 200 most common Persian verbs is a good place to practice this.
3. Memorize the short stems as whole words. There are only a handful (go, say, want, come, give, become, can, put, sit), and they cover a large share of daily talk.
4. Apply the rules to listening, not just reading. When you watch an Iranian film, pause on a line and try to “translate” it back into written Persian. This trains your ear fast.
5. Speak colloquially from day one. If your goal is conversation, say خوبه and می‌خوام out loud. Iranians will understand the written forms, but the spoken ones make you sound natural.
6. Keep writing in the written register. For homework, emails and anything formal, use the full forms. A good habit is to read a short news item in written Persian and then retell it out loud in spoken Persian.

Which register should you focus on?

Every serious learner eventually needs both, but your goal decides where to start. Pick the option that fits you best.

Common questions about spoken and written Persian

Is spoken Persian the same everywhere in Iran?

No. The colloquial forms on this page are Tehrani, which is the standard spoken variety heard on national TV dramas and understood across Iran. Other cities have their own accents, and Dari in Afghanistan and Tajik in Tajikistan have their own colloquial forms. Tehrani is the best first choice for most learners.

Will Iranians understand me if I speak in written Persian?

Yes. Everyone understands the written forms because they learn them at school. You will simply sound formal, a bit like someone saying “I shall not” in casual English. Mixing in the spoken forms as you learn them is the natural next step.

Is it wrong to write the spoken forms?

Not in informal writing. Texts, chats, social posts and dialogue in fiction often use spellings like میام and خونه. In school work, business emails and official writing, use the written forms.
