Persian does not have one spelling for every social situation. A newspaper normally writes میخواهم “I want,” while a friend may type میخوام to represent the Tehran pronunciation. Both belong to Iranian Persian, but they do different work: the first preserves the shared written standard; the second makes an informal speaking voice visible.
The safest principle is standard first, deliberate transcription second. Learn the dictionary form and its ordinary spelling before learning a colloquial counterpart. Then choose a whole register for the message instead of shortening whichever words happen to look familiar. The difference is not “correct Persian” versus “bad Persian”; it is standardized writing versus a partly conventional way of representing speech.
Three levels that learners must keep apart
The word spoken describes pronunciation, while colloquial spelling describes what is put on the page. A speaker can pronounce a standard-written sentence naturally, and a text message can spell reductions that formal writing leaves invisible.
| Level | Typical setting | Representative forms | Status |
|---|---|---|---|
| Written standard | essays, news, applications | میخواهم، میرود، آنها را، است | default edited spelling |
| Careful spoken standard | presentation, reading aloud, careful interview | usually the same visible forms, pronounced fluently | speech without extensive Tehran reduction |
| Colloquial Tehran spelling | texts, dialogue, informal posts | میخوام، میره، اونا رو، ـه | informal, regional: Tehran |
امروز میخواهم زودتر به خانه بروم.
emruz mi-khâham zudtar be khâne beravam.
Today I want to go home earlier. (careful-spoken standard)
امروز میخوام زودتر برم خونه.
emruz mi-khâm zudtar beram khune.
I wanna head home earlier today. (informal, regional: Tehran)
The second sentence is not the first sentence with vowels omitted at random. Several choices align: میخواهم → میخوام, subordinate بروم → برم, and خانه → خونه. That clustering is why colloquial spelling is best learned as a system.
What informal writers commonly put on the page
There is no single academy-enforced spelling standard for casual messages. Even so, recurrent mappings make most Tehran writing predictable. This guide keeps Persian ک and ی and uses ZWNJ after productive می/نمی even in colloquial forms. Real messages sometimes omit the ZWNJ, but omission is a typing habit, not a new pronunciation.
| Function | Standard | Colloquial Tehran | What changed |
|---|---|---|---|
| first singular “want” | میخواهم | میخوام | high-frequency stem reduction |
| third singular “go” | میرود | میره | colloquial stem plus ending |
| third plural “say” | میگویند | میگن | reduced stem and ـن |
| object marker | را | رو / ـو | spoken clitic represented |
| plural | کتابها | کتابا | ه is not represented |
| third-singular copula | است | ـه؛ پس از مصوت گاهی ـست | host-conditioned spoken allomorphs |
لیلا میگه فایل رو امشب میفرسته.
Leylâ mi-ge fâyl ro emshab mi-fereste.
Leila says she'll send the file tonight. (informal, regional: Tehran)
خواهشمندم گزارش را تا پایان امروز بفرستید.
khâheshmand-am gozâresh râ tâ pâyân-e emruz beferestid.
Please send the report by the end of today. (written standard)
The dictionary form is the conversion anchor
A dictionary lists خواستن، رفتن، گفتن، آمدن, not every spelling found in a chat. When you meet میخواد، میره، میگه، میاد, connect each one back to its standard infinitive and present stem. This two-way link matters: listening requires standard-to-colloquial recognition, while formal writing requires colloquial-to-standard recovery.
اونا فردا با قطار میان.
unâ fardâ bâ qatâr miyân.
They're coming by train tomorrow. (informal, regional: Tehran)
آنها فردا با قطار میآیند.
ân-hâ fardâ bâ qatâr mi-âyand.
They are coming by train tomorrow. (careful-spoken standard)
Some correspondences are broadly productive: colloquial third plural often ends in ـن, and second plural/polite often ends in ـین. Others are lexical and must be learned: میگویم → میگم is not obtained merely by deleting the final consonant. The present stem changes too. The Present Stem remains the best anchor for understanding what belongs to the verb.
Social media conventions are variable, not structureless
Friends vary in how strongly they represent speech. One person may type میخواهم while speaking mi-khâm; another types میخوام. Some write رو separately, while after a pronoun many use a bound spelling such as اونو. Such variation reflects speed, keyboard habits, audience, and desired voice.
What remains stable is the contrast in setting. A scholarship application, academic paper, or official notice normally retains standard forms. A comic dialogue or private message may spell the same speaker's reductions. A public-facing brand post can deliberately sit between these poles, but that is an editorial choice, not evidence that all forms are interchangeable.
درخواست شما دریافت شد و نتیجه اعلام خواهد شد.
darkhâst-e shomâ daryâft shod va natije e'lâm khâhad shod.
Your application was received, and the result will be announced. (formal written)
پیامت رسید؛ تا عصر بهت خبر میدم.
peyâm-et resid; tâ asr behet khabar mi-dam.
I got your message; I'll let you know by this afternoon. (informal, regional: Tehran)
A short two-register exchange
مسئول پذیرش گفت: «مدارک شما کامل است.»
mas'ul-e paziresh goft: «madârek-e shomâ kâmel ast.»
The admissions officer said, ‘Your documents are complete.’ (careful institutional speech)
بعد به دوستم پیام دادم: «همهچی کامله؛ فردا میام ثبتنام.»
ba'd be dust-am peyâm dâdam: «hame-chi kâmele; fardâ miyâm sabt-nâm.»
Then I texted my friend, ‘Everything's complete; I'm coming to register tomorrow.’ (informal, regional: Tehran)
The change of spelling is licensed by a change of voice and audience. Quotation boundaries can therefore contain two registers without creating an accidental hybrid.
Common Mistakes
1. Omitting standard word boundaries because the sentence is informal
❌ میخوام فردا بیام.
Incorrect house orthography — the productive prefix می requires a ZWNJ before the verbal stem.
✅ میخوام فردا بیام.
mi-khâm fardâ biyâm.
I want to come tomorrow. (informal, regional: Tehran; house spelling)
2. Treating one colloquial word as a complete register conversion
⚠️ اونا گزارش را فردا ارسال خواهند کرد.
unâ gozâresh râ fardâ ersâl khâhand kard.
They will send the report tomorrow. (grammatical, but conspicuously hybrid without a motivated style shift)
✅ آنها گزارش را فردا ارسال خواهند کرد.
ân-hâ gozâresh râ fardâ ersâl khâhand kard.
They will send the report tomorrow. (formal written)
3. Inventing a hybrid stem and ending
❌ شما کی میآییدن؟
Incorrect — two different second/plural suffixes have been stacked on one finite verb.
✅ شما کی میاین؟
shomâ key miyâyin?
When are you coming? (informal, regional: Tehran; polite/plural)
4. Copying a regional form and calling it universal Iranian speech
⚠️ این شکل را همهی ایرانیها در گفتوگو به کار میبرند.
in shekl râ hame-ye irâni-hâ dar goft-o-gu be kâr mi-barand.
All Iranians use this form in conversation. (well-formed Persian, but an overgeneralization when the form is specifically Tehran colloquial)
✅ این شکل در گفتوگوی روزمرهی تهران رایج است.
in shekl dar goft-o-gu-ye ruzmarre-ye Tehrân râyej ast.
This form is common in everyday Tehran conversation.
Key Takeaways
- Standard spelling represents the shared written language; colloquial spelling makes a particular speaking voice visible.
- Informal Tehran writing has recurring mappings, but real-world ZWNJ and attachment practices vary.
- Preserve standard forms as dictionary anchors and learn to convert in both directions.
- A colloquial sentence coordinates stems, endings, copulas, pronouns, and function words; it is not produced by random deletion.
- Dari and Tajik have their own norms. A form from either variety should never be relabeled as unmarked Iranian colloquial Persian.
