Common Persian Grammar Mistakes: Test Yourself

<![CDATA[
I’ve been teaching Farsi for years, and the same grammar mistakes show up constantly. Not random mistakes. the same ten patterns, over and over, regardless of the student’s native language. English speakers make them. Arabic speakers make them. Even heritage speakers who grew up hearing Farsi at home make them. These are the traps that Persian grammar sets for everyone.

This post has 30 sentences with common errors. Your job: find the mistake in each one and correct it. I’ve organized them by error type, with explanations after each section. Keep score. your total tells you where you stand.

How to Use This Test

Read each sentence. Identify what’s wrong. Write your correction before checking the answer. No peeking.

Scoring:

  • 25-30 correct: Your grammar is solid. You’re catching things most learners miss.
  • 18-24 correct: Good foundation, but some patterns need work.
  • 12-17 correct: You know the basics but need targeted practice on specific error types.
  • Under 12: Start with the fundamentals. check the grammar exercises hub for level-appropriate practice.

Section 1: Ezafe Errors (سه اضافه)

The ezafe (اضافه. ezâfe) is that unstressed "-e" connecting nouns to modifiers. Getting it wrong is the most common mistake at every level.

Sentence 1

کتاب بزرگ من روی میز است.
ketâb bozorg man ruye miz ast.

Show answer

✅ کتابِ بزرگِ من روی میز است.
ketâb-e bozorg-e man ruye miz ast.
“My big book is on the table.”

Error: Missing ezafe between کتاب and بزرگ, and between بزرگ and من. When a noun has an adjective and a possessive, the ezafe chain connects all three: noun-e adjective-e possessor.

Sentence 2

❌ رنگِ این ماشینِ خیلی قشنگه.
rang-e in mâshin-e kheyli ghashange.

Show answer

✅ رنگِ این ماشین خیلی قشنگه.
rang-e in mâshin kheyli ghashange.
“The color of this car is very pretty.”

Error: False ezafe before خیلی. Here, خیلی قشنگه is the predicate (is very pretty), not a modifier of ماشین. The ezafe after ماشین makes it sound like “very pretty car” instead of “the car is very pretty.”

Sentence 3

❌ دوستِ خوبِ‌ام دیروز اومد.
dust-e khub-e-am diruz umad.

Show answer

✅ دوستِ خوبَم دیروز اومد.
dust-e khub-am diruz umad.
“My good friend came yesterday.”

Error: After an adjective, the possessive suffix attaches directly. no extra ezafe. It’s خوبم not خوبِ‌ام. The ezafe is between noun and adjective, but the possessive clitic replaces the second ezafe.

Section 2: را (Râ) Marker Errors

The object marker را (). or رو (ro) in spoken. is one of the trickiest parts of Persian grammar for non-natives.

Sentence 4

❌ من یک کتاب را خریدم.
man yek ketâb râ kharidam.

Show answer

✅ من یک کتاب خریدم.
man yek ketâb kharidam.
“I bought a book.”

Error: را marks specific, definite direct objects. یک کتاب (a book) is indefinite. you don’t know which book. No را needed. Compare: کتاب را خریدم (I bought the book). that’s definite, so را is correct.

Sentence 5

❌ من به آن فیلم را دیدم.
man be ân film râ didam.

Show answer

✅ من آن فیلم را دیدم.
man ân film râ didam.
“I watched that movie.”

Error: را marks direct objects. Direct objects don’t get a preposition. Using both به (to) and را together on the same noun is a contradiction. it can’t be both an indirect and direct object. Drop the به.

Sentence 6

غذا خوشمزه بود.
ghazâ khoshmaze bud. (meaning: "The food was delicious.")

Show answer

✅ غذا خوشمزه بود.
This sentence is actually correct. Trick question.

Why: غذا is the subject here, not the object. No را needed. Many learners over-apply را by adding it to every definite noun, but it only marks direct objects, not subjects or predicate complements.

Sentence 7

❌ من رفتم مغازه را.
man raftam maghâze râ.

Show answer

✅ من رفتم مغازه / من به مغازه رفتم.
man raftam maghâze / man be maghâze raftam.
“I went to the store.”

Error: رفتن (to go) is intransitive. it doesn’t take a direct object. You go to a place (با preposition) not a place (with را). This is a direct transfer from English “I went the store.”

Section 3: Formal in Casual Speech

Using bookish (کتابی. ketâbi) forms in casual conversation. Technically correct but socially wrong.

Sentence 8

❌ (In casual conversation:) من می‌خواهم به سینما بروم.
man mikhâham be sinamâ beravam.

Show answer

✅ (Casual:) من می‌خوام برم سینما.
man mikhâm beram sinamâ.
“I wanna go to the movies.”

Error: می‌خواهم and بروم are formal written forms. In spoken Tehrani Farsi, they become می‌خوام and برم. Using the formal versions in casual speech sounds robotic. like saying “I wish to proceed to the cinema” in English.

Sentence 9

❌ (Texting a friend:) آیا فردا وقت داری؟
âyâ fardâ vaght dâri?

Show answer

✅ (Texting:) فردا وقت داری؟
fardâ vaght dâri?
“You free tomorrow?”

Error: آیا is the formal question marker. In casual speech and texting, you just use intonation (or a question mark in writing). آیا in a text to a friend is like starting a text with “Do you perchance…”

Sentence 10

❌ (Talking to your roommate:) لطفاً در را ببندید.
lotfan dar râ bebandid.

Show answer

✅ (To roommate:) درو ببند.
daro beband.
“Close the door.”

Error: ببندید is the formal “you” (شما) conjugation. With your roommate, use تو form: ببند. Also, در را becomes درو in spoken Farsi. Using شما form with a close friend or roommate creates awkward distance.

Section 4: English Word Order

Persian is SOV (Subject-Object-Verb). English is SVO. This transfer error is everywhere.

Sentence 11

❌ من دوست دارم تو.
man dust dâram to.

Show answer

✅ من تو رو دوست دارم.
man to ro dust dâram.
“I like/love you.”

Error: In English, “I love you” puts the object last. In Persian, the object comes before the verb. تو رو (you + object marker) must come before دوست دارم (like/love).

Sentence 12

❌ من خوردم غذا دیشب.
man khordam ghazâ dishab.

Show answer

✅ من دیشب غذا خوردم.
man dishab ghazâ khordam.
“I ate food last night.”

Error: Multiple word order problems. Time adverbs typically come before the object. The verb goes at the end. Standard order: Subject + Time + Object + Verb.

Sentence 13

❌ چرا تو نمی‌آیی به مهمونی؟
cherâ to nemiâyi be mehmuni?

Show answer

✅ چرا نمیای مهمونی؟ / چرا به مهمونی نمیای؟
cherâ nemiây mehmuni? / cherâ be mehmuni nemiây?
“Why aren’t you coming to the party?”

Error: The destination/prepositional phrase should come before the verb, not after. Also, نمی‌آیی is formal; نمیای is casual spoken form.

Section 5: Wrong Preposition

Sentence 14

❌ من فکر درباره تو می‌کنم.
man fekr darbâre-ye to mikonam.

Show answer

✅ من به تو فکر می‌کنم.
man be to fekr mikonam.
“I think about you.”

Error: “Think about” in English uses “about,” so learners reach for درباره (about). But فکر کردن takes the preposition به, not درباره. Each compound verb has its own preposition. you have to learn them individually.

Sentence 15

❌ من از تهران در تابستان رفتم.
man az tehrân dar tâbestân raftam.

Show answer

✅ من تابستان از تهران رفتم.
man tâbestân az tehrân raftam.
“I left Tehran in the summer.”

Error: در (in) isn’t used for seasons in casual Farsi the way “in” is used in English. Time expressions like تابستان (summer) work as bare adverbs without a preposition. Also, word order: time comes before the prepositional phrase.

Sentence 16

❌ من منتظر برای تو هستم.
man montazer barâye to hastam.

Show answer

✅ من منتظر تو هستم.
man montazer-e to hastam.
“I’m waiting for you.”

Error: “Wait for” in English doesn’t mean you need برای in Farsi. منتظر takes a direct ezafe connection to its object: منتظرِ تو. No preposition needed.

Section 6: Compound Verb Errors

Persian compound verbs (فعل مرکب. fe’l-e morakkab) combine a noun/adjective with a light verb. Breaking them up or combining them wrong is extremely common.

Sentence 17

❌ من تلفن کردم به تو.
man telefon kardam be to.

Show answer

✅ من به تو تلفن کردم / من بهت زنگ زدم.
man be to telefon kardam / man behet zang zadam.
“I called you.”

Error: The prepositional phrase (به تو) should come before the compound verb, not split it. In Persian, the compound verb stays together at the end. In casual speech, زنگ زدن (to ring) is more common than تلفن کردن.

Sentence 18

❌ من بازی فوتبال کردم.
man bâzi futbâl kardam.

Show answer

✅ من فوتبال بازی کردم.
man futbâl bâzi kardam.
“I played football.”

Error: In the compound verb بازی کردن (to play), the object (what you’re playing) goes before بازی, not after it. It’s “football play did” not “play football did.”

Sentence 19

❌ من دوش گرفتم. (meaning: I took a shower. using گرفتن)

Show answer

✅ من دوش گرفتم.
This is actually correct. Another trick question.

Why: دوش گرفتن (to take a shower) does use گرفتن (to take). Not every compound verb uses کردن. Some use گرفتن, زدن, خوردن, or other light verbs. The mistake would be saying دوش کردم. that’s wrong.

Section 7: Subjunctive Confusion

Sentence 20

❌ من می‌خوام که می‌رم خونه.
man mikhâm ke miram khune.

Show answer

✅ من می‌خوام برم خونه.
man mikhâm beram khune.
“I want to go home.”

Error: After می‌خوام (I want), the following verb must be subjunctive: برم (not میرم). The subjunctive drops the می- prefix and uses the ب- prefix. Also, the که is unnecessary here. it’s optional and usually dropped in casual speech.

Sentence 21

❌ لازمه که من می‌خونم این کتاب رو.
lâzeme ke man mikhun am in ketâb ro.

Show answer

✅ لازمه این کتاب رو بخونم.
lâzeme in ketâb ro bekhun am.
“I need to read this book.”

Error: لازمه (it’s necessary) requires subjunctive: بخونم not می‌خونم. Word order also needed fixing. object before verb.

Sentence 22

❌ شاید من می‌تونم بیام.
shâyad man mitunam biyâm.

Show answer

✅ شاید بتونم بیام.
shâyad betunam biyâm.
“Maybe I can come.”

Error: شاید (maybe) triggers subjunctive. می‌تونم must become بتونم. The من is also unnecessary. the verb conjugation already shows the subject.

Section 8: Register Mixing

Sentence 23

❌ (In a formal email:) سلام، می‌خوام یه جلسه بذاریم.
salâm, mikhâm ye jalase bezârim.

Show answer

✅ (Formal email:) با سلام و احترام، خواهشمند است جلسه‌ای هماهنگ گردد.
bâ salâm va ehterâm, khâheshmand ast jalase-i hamâhang gardad.
“With greetings and respect, it is requested that a meeting be coordinated.”

Error: Casual spoken register in a formal email. سلام alone is too casual. می‌خوام is spoken form. یه instead of یک. بذاریم is colloquial. Formal emails require formal written register throughout.

Sentence 24

❌ (Chatting with friends:) بنده قصد دارم به آن مکان عزیمت نمایم.
bande ghasd dâram be ân makân azimat namâyam.

Show answer

✅ (With friends:) می‌خوام برم اونجا.
mikhâm beram unjâ.
“I wanna go there.”

Error: Ultra-formal, almost archaic language in a casual context. بنده (this humble servant), عزیمت نمایم (to depart. formal), مکان (place. formal). With friends, this sounds absurd. like wearing a tuxedo to a barbecue.

Section 9: Miscellaneous Errors

Sentence 25

❌ من داشتم رفتم.
man dâshtam raftam.

Show answer

✅ من داشتم می‌رفتم.
man dâshtam miraftam.
“I was going.”

Error: The progressive auxiliary داشتن requires the main verb in the imperfective (with می-). داشتم رفتم uses the simple past. that’s not how progressive works in Farsi.

Sentence 26

❌ من سه تا بچه‌ها دارم.
man se tâ bachche-hâ dâram.

Show answer

✅ من سه تا بچه دارم.
man se tâ bachche dâram.
“I have three children.”

Error: When you use a number + تا (counter), the noun stays singular. Three children = سه تا بچه, not سه تا بچه‌ها. The number already indicates plurality.

Sentence 27

❌ من خوشحالم از دیدن تو.
man khoshhâlam az didan-e to.

Show answer

✅ از دیدنت خوشحالم.
az didanet khoshhâlam.
“I’m happy to see you.”

Error: Not technically wrong, but unnatural word order and phrasing. In natural Farsi, the prepositional phrase comes first. Also, دیدن تو is usually contracted to دیدنت in casual speech.

Sentence 28

❌ من همیشه زود خوابیدن می‌کنم.
man hamishe zud khâbidan mikonam.

Show answer

✅ من همیشه زود می‌خوابم.
man hamishe zud mikhâbam.
“I always go to sleep early.”

Error: خوابیدن (to sleep) is a simple verb, not a compound verb. You conjugate it directly (می‌خوابم), you don’t add کردن to the infinitive. This error comes from learners treating all verbs like compound verbs.

Sentence 29

❌ ایران یک کشور زیبایی است.
irân yek keshvar-e zibâyi ast.

Show answer

✅ ایران کشور زیبایی است. / ایران یک کشور زیبا است.
irân keshvar-e zibâyi ast. / irân yek keshvar-e zibâ ast.
“Iran is a beautiful country.”

Error: You can say کشور زیبایی (with the indefinite ی) without یک, or use یک کشور زیبا without the indefinite ی ending. Using both یک and the indefinite ی suffix is redundant. it’s marking indefiniteness twice.

Sentence 30

❌ من هر روز ورزش می‌کنم در پارک.
man har ruz varzesh mikonam dar pârk.

Show answer

✅ من هر روز در پارک ورزش می‌کنم.
man har ruz dar pârk varzesh mikonam.
“I exercise in the park every day.”

Error: Location goes before the verb, not after. Persian word order puts almost everything before the verb: Subject + Time + Location + Object/Compound verb element + Verb.

ZabanYar has grammar quizzes that adapt to your level. it identifies your specific weak patterns and drills them until they’re automatic. Way more efficient than reviewing random exercises.

FAQ

What is the most common grammar mistake in Persian?

Wrong word order is the most frequent error for English speakers learning Farsi. English uses SVO (Subject-Verb-Object) while Persian uses SOV (Subject-Object-Verb). This means the verb goes at the end of the sentence in Persian, and objects, prepositional phrases, and adverbs all come before it. It takes sustained practice to override the English instinct to put the verb in the middle.

How do I know when to use را in Persian?

Use را () when the direct object is specific and definite. meaning both you and the listener know which thing you’re talking about. “I read the book” (definite) needs را: کتاب را خواندم. “I read a book” (indefinite) does not: یک کتاب خواندم. If you can point at the thing or you’ve already mentioned it, use را. If it’s just “any” or “some,” don’t.

Why does formal Persian sound so different from spoken Farsi?

Persian has a wide gap between its written/formal register and its spoken/casual register. wider than English. Formal Persian preserves verb forms, pronunciations, and vocabulary that spoken Farsi has simplified over centuries. It’s similar to the difference between Modern Standard Arabic and spoken dialects. Most language courses teach formal Persian, which is why learners sound unnatural in conversation. Learning both registers from the start is essential.

What is the ezafe in Farsi and why is it so confusing?

The ezafe is an unstressed “-e” sound that connects nouns to their modifiers (adjectives, possessors, other nouns). It’s confusing because it’s not written in standard Persian script. you have to know it’s there from context. کتاب بزرگ is read as ketâb-e bozorg (big book) with an invisible ezafe. The main rule: any time a noun is directly followed by its adjective or possessor, there’s an ezafe between them.

How can I practice Persian grammar on my own?

Three effective methods: (1) Error correction exercises like this post. they force you to notice patterns. (2) Shadowing Iranian content. repeat what you hear in movies or podcasts and compare your grammar to theirs. (3) Writing short paragraphs about your day in Farsi, then having a native speaker check them. Grammar apps with spaced repetition also help for drilling specific patterns like verb conjugation and ezafe chains.
