10 Common Farsi Writing Mistakes — How to Fix Each One
Even learners with strong spoken Persian make consistent errors in writing. Farsi script has rules that differ significantly from any Latin-based language — from the direction of writing to invisible short vowels to letter forms that change based on position. This guide covers the 10 most common Farsi writing mistakes with correct and incorrect examples for each, so you know exactly what to fix.

These 10 mistakes appear repeatedly in GCSE Persian writing assessments and are among the most common reasons students lose marks. Work through each one and you will immediately improve your written Farsi. See our GCSE Persian tutoring programme for targeted exam preparation.
The 10 Most Common Farsi Writing Mistakes
The half-space (نیمفاصله — nim-fāsele) is a zero-width character placed between certain word parts that are grammatically connected but should not fully merge in writing. The most critical case is the verb prefix می (the present/imperfect marker) — it must be connected to the verb with a half-space, not a full space and not without any space.
✗ Wrong
میروم / می روم miram / mi ravam Fully joined or fully separated✓ Correct
میروم miram Half-space between می and روم✗ Wrong
نمیدانم / نمی دانم✓ Correct
نمیدانم I don’t know💡 How to fix it
In Microsoft Word, use Ctrl+Shift+2 to insert a half-space. On iOS/Android Persian keyboards, hold the space bar briefly. The rule: می، نمی، همی، میتوانم، نمیتوانم — always half-space before the verb stem.
Persian has several groups of letters that share the same base shape but differ only in the number and position of dots. Mixing them up produces completely different words — or nonsense. The most commonly confused pairs:
| Letter pair | Sound | Example of confusion | Correct |
|---|---|---|---|
| ح / خ | h vs kh (throat) | حانه (hāne with ح) | خانه |
| س / ص | both = s sound | صبز instead of سبز | سبز (green) |
| ز / ذ / ض / ظ | all = z sound | Using ض in native Persian words | ز is default; ذ/ض/ظ mostly in Arabic loanwords |
| ع / غ | glottal vs gh | غلم instead of علم | علم (knowledge) |
| ت / ث | both = t/s sound | ثشکر instead of تشکر | تشکر (thanks) |
💡 How to fix it
Learn which letters appear in which words — particularly the distinction between ح and خ (which have different sounds) and between the four z-letters (ز، ذ، ض، ظ). The letter ز is by far the most common in native Persian words. When in doubt about Arabic loanwords, check a dictionary.
This is one of the most common GCSE mistakes. Spoken Persian differs significantly from written formal Persian, and learners who have absorbed Farsi through family conversation often write words as they are spoken rather than as they are formally written.
✗ Colloquial (spoken) — wrong in formal writing
خونه، میخوام، اومدم، چیه khune, mikham, umadam, chiye✓ Formal written — correct
خانه، میخواهم، آمدم، چیست khāne, mikhāham, āmadam, chist| Spoken form ✗ | Written form ✓ | English |
|---|---|---|
| خونه | خانه | House |
| میخوام | میخواهم | I want |
| اومدم | آمدم | I came |
| میره | میرود | He/she goes |
| نیست که | نیست که (✓ same) | — |
| داره | دارد | He/she has |
💡 How to fix it
In formal writing, essays, and GCSE exams: always use the full formal form. است not ه, میرود not میره, خانه not خونه. The gap between spoken and written Persian is large — treat them as two related but distinct registers.
The letter alef has several forms in Persian, and choosing the wrong one changes the meaning of a word. The most critical distinction for learners is between آ (alef with madde — a long “ā” sound) and ا (plain alef). Words that start with a long “ā” sound must use آ, not ا.
✗ Wrong
اب، امد، اسمان Plain alef where ā-sound words need آ✓ Correct
آب، آمد، آسمان Water, came, sky — all start with long ā💡 How to fix it
Key rule: if a word starts with a long “ā” sound (like the “a” in “father”), it needs آ (alef with madde). Common words: آب (water), آمد (came), آسمان (sky), آموزش (education), آزاد (free), آرام (calm). Memorise these as a group.
At the end of words, the letter ی can function as a vowel (the “-i” or “-ī” ending) or as the indefinite marker (یک — a/an). Confusing its form with the Arabic alef maqsura (ى — which appears in Arabic loanwords) causes spelling errors in formal writing. In Persian, word-final ی almost always has two dots; in Arabic-derived words written in Persian it may not.
✗ Common error
کتابى (Arabic form) Wrong form of ی in Persian context✓ Correct Persian
کتابی A book — ی with two dotsThe hamze (ء) creates a glottal stop — a brief pause in the throat between vowel sounds. Omitting it changes pronunciation and meaning. It most commonly appears in the middle of words as ئ (ye with hamze) or at the end of words as a standalone ء.
✗ Wrong — hamze missing
مسله، جزء، موسس Hamze omitted — changes pronunciation✓ Correct
مسئله، جزء، مؤسس Hamze present — mas’ale, joz’, mo’asses💡 Key words to memorise
مسئله (mas’ale — problem/matter), مسئول (mas’ul — responsible), تأثیر (ta’sir — influence/effect), مؤسسه (mo’assese — institution), رأس (ra’s — head/top). These words are frequently misspelled by omitting the hamze.
Arabic has a letter called ta marbuta (ة) — a ه with two dots — used at the end of feminine nouns. This letter does not exist in Persian. However, learners familiar with Arabic sometimes write ة at the end of Persian words, particularly Arabic loanwords. In Persian formal writing, word-final ه is always written without the two dots.
✗ Wrong (Arabic form)
مدرسة، خلاصة Arabic ta marbuta — not used in Persian✓ Correct Persian
مدرسه، خلاصه Plain ه at word end — always in PersianHeritage learners who think in English sometimes write sentences in SVO order (Subject-Verb-Object) rather than Persian SOV order (Subject-Object-Verb). The verb must come at the end of the Persian sentence — not in the middle as in English.
✗ English order in Persian
من میخورم چای Man mikhoram chāy I + drink + tea — verb before object✓ Correct Persian SOV
من چای میخورم Man chāy mikhoram I + tea + drink — verb at end💡 How to fix it
Before writing any Persian sentence, mentally place the verb at the end first, then build backwards. Also remember: adjectives come after the noun (not before as in English) connected by the ezāfe. See our Persian sentence structure guide for the full rules.
The ezāfe (-e or -ye) connecting noun to adjective or possessive is usually not written in normal Persian text — it is an implied vowel that readers understand from context. However, when it must be shown (in children’s books or when clarity is needed), it should be written correctly. The more common error is using ی (ye) instead of the correct form after words ending in ه or vowels.
✗ Wrong ezāfe form
خانهی (acceptable but older) کتابی من (wrong — ی here means indefinite “a”)✓ Correct
خانهام (my house) کتاب من (my book — ezāfe implied)Persian uses different punctuation conventions from English. The most important differences: the Persian comma is ، (not ,), quotation marks differ, and the question mark ? is used the same way as English but some formal texts use a Persian-specific form. Writing right-to-left text with left-to-right punctuation causes formatting issues.
| English mark | Persian equivalent | Notes |
|---|---|---|
| , | ، | Persian comma — mirrored, slightly different shape |
| ; | ؛ | Persian semicolon |
| ? | ? | Same as English — used identically |
| ! | ! | Same as English |
| “quote” | «quote» | Persian uses guillemets — double angle brackets |

| # | Mistake | Fix |
|---|---|---|
| 1 | Missing half-space with می | میروم not میروم or می روم |

Frequently Asked Questions
What is the most common Farsi writing mistake?
The most widespread mistake is incorrect use of the half-space (نیمفاصله) with the verb prefix می. Learners write میروم (fully joined) or می روم (fully separated) instead of the correct میروم (with half-space). This applies to all verbs with می — میخواهم، نمیتوانم، میرفتم. The half-space is essential in formal written Persian and is checked in GCSE marking.
What is the difference between formal and colloquial Farsi writing?
Formal written Persian uses classical vocabulary and grammar forms — خانه (house), میخواهم (I want), آمدم (I came). Colloquial spoken Persian uses shortened forms — خونه، میخوام، اومدم. In formal essays, exams, letters, and academic writing, always use the formal written forms. Using colloquial spelling in formal contexts is one of the most common errors GCSE Persian students make.
How do I know when to use آ versus ا in Farsi?
Use آ (alef with madde) at the beginning of words that start with a long “ā” sound — like the “a” in “father.” Common examples: آب (water), آمد (came), آسمان (sky), آزاد (free), آرام (calm), آموزش (education). Use plain ا when the alef makes a short vowel sound or appears in the middle of a word. When in doubt, check a dictionary — the distinction is always shown.
Why do GCSE Persian students lose marks for writing mistakes?
GCSE Persian writing is assessed on grammatical accuracy, vocabulary range, and register. The most penalised errors are: colloquial forms in formal writing, missing half-spaces with می، incorrect alef forms (ا vs آ)، missing hamze in words like مسئله، and English word order (verb not at the end). A Danaa tutor who knows the GCSE mark scheme can identify which of these errors a student makes consistently and target them directly.
