Every Persian verb has a present stem used in the present indicative, subjunctive, imperative, and several derived forms. For رفتن “to go,” the past stem is predictably رفت, but the present stem is رو rav: میروم “I go.” Unlike the past stem, the present stem cannot in general be recovered by removing one fixed ending from the infinitive.
This is the genuinely difficult half of the two-stem system. Historical sound changes created recurring correspondences, but they are not reliable enough to generate every stem. Learn each new verb as an infinitive plus a present stem—دیدن (بین), گفتن (گو), نوشتن (نویس)—and use the stem productively once it is known.
Where the present stem appears
The most visible A1 pattern is می + present stem + personal ending. With رو, the six written-standard forms begin میروم، میروی، میرود.... Other present-system constructions use a different prefix or no می, but preserve the same stem.
| Construction | Example built on رو | Meaning | Register |
|---|---|---|---|
| present indicative | میروم | I go / I am going | neutral standard |
| present subjunctive | بروم | that I go / I should go | all modern registers |
| imperative | برو | go! | neutral; singular informal command |
| negative present | نمیروم | I do not go | neutral standard |
هر صبح با اتوبوس به دانشگاه میروم.
har sobh bâ otobus be dâneshgâh mi-ravam.
Every morning I go to the university by bus. (neutral standard; present stem رو)
خواهش میکنم اینجا منتظر بمانید.
khâhesh mi-konam injâ montazer bemânid.
Please wait here. (polite standard; present stem مان in بمانید)
The prefix and ending tell you which construction and person you have; the present stem carries the lexical identity of the verb. The same architecture recurs across thousands of forms.
Why it cannot simply be guessed
The infinitive and past stem form one predictable pair: گفتن → گفت. The present stem گو, however, reflects older morphology and later sound change. Sometimes a learner sees a pattern—past خواند, present خوان; past خورد, present خور—but that pattern does not predict دید → بین or رفت → رو.

این تابلو را از آنجا خوب میبینی؟
in tâblo râ az ânjâ khub mi-bini?
Can you see this sign well from there? (careful spoken standard; بین)
خواهرم برای یک مجلهی علمی مینویسد.
khâhar-am barâ-ye yek majalle-ye elmi mi-nevisad.
My sister writes for a scientific magazine. (neutral standard; نویس)
این کارگاه میزهای چوبی میسازد.
in kârgâh miz-hâ-ye chubi mi-sâzad.
This workshop makes wooden tables. (neutral standard; ساز)
Dictionary notation and a practical learning method
A dictionary entry may show نوشتن، نویس or نوشتن (نویس). The first form is the infinitive; the shorter second form is the present stem. Some learner dictionaries instead give a full first-person present such as مینویسم. Strip the known prefix می and ending ـم, and the remaining lexical core is نویس.
This differs sharply from the mechanical operation described on The Infinitive and Past Stem: final ن always yields the past stem, but no single deletion always yields the present stem.
Do not record only a translated English verb. One English verb can map to several Persian verbs, and one Persian present stem can look remote from its infinitive. A useful vocabulary card contains گرفتن — گیر — to take/get. From that small entry you can recognize both گرفتم and میگیرم.
بیشتر وقتها بلیت را از سایت شرکت میگیرم.
bishtar-e vaqt-hâ belit râ az sâyt-e sherkat mi-giram.
I usually get the ticket through the company's website. (neutral standard; گیر)
هنوز جواب این سؤال را نمیدانم.
hanuz javâb-e in so'âl râ nemi-dânam.
I still don't know the answer to this question. (neutral standard; دان)
Standard forms and colloquial reductions
The present stems on this page belong to standard Iranian Persian and careful speech. Everyday Tehran pronunciation can obscure them: standard میروم corresponds to colloquial میرم, and میآیم to میام (informal, regional: Tehran). These are systematic spoken forms, not evidence for replacing the dictionary stems with invented spellings in formal prose.
Both of the following are natural in their stated registers:
فردا ساعت ده میآیم.
fardâ sâ'at-e dah mi-âyam.
I will come at ten tomorrow. (careful spoken standard)
فردا ساعت ده میام.
fardâ sâ'at-e dah miyâm.
I'll come at ten tomorrow. (informal, regional: Tehran)
Do not combine a colloquial surface stem with a formal ending at random. Learn the standard paradigm first and treat the colloquial paradigm as a coherent register system.
A short exchange
هر روز اینجا ناهار میخوری؟
har ruz injâ nâhâr mi-khori?
Do you eat lunch here every day? (careful spoken standard)
نه، بیشتر روزها از خانه غذا میآورم.
na, bishtar-e ruz-hâ az khâne ghazâ mi-âvaram.
No, most days I bring food from home. (careful spoken standard; present stem آور)
Common Mistakes
1. Using the past stem with present endings
❌ او هر صبح به اداره میرفتد.
Incorrect — present رفتن uses the stem رو; میرفت belongs to the past imperfect system and never takes ـد here.
✅ او هر صبح با مترو به اداره میرود.
u har sobh bâ metro be edâre mi-ravad.
He or she goes to the office by metro every morning.
2. Guessing نویشت from نوشتن
❌ مدیر پاسخ را مینویشت.
Incorrect as a present form — the present stem of نوشتن is نویس.
✅ مدیر پاسخ را خودش مینویسد.
modir pâsokh râ khod-ash mi-nevisad.
The manager writes the reply personally.
3. Moving می away from the verb
❌ سارا می هر هفته این کتاب را خواند.
Incorrect — می is a bound prefix and stays attached to the present stem with a ZWNJ.
✅ سارا هر هفته یک فصل از این کتاب را میخواند.
sârâ har hafte yek fasl az in ketâb râ mi-khânad.
Sara reads one chapter of this book every week.
4. Mismatching the ending after a correct stem
❌ تو این خیابان را خوب میشناسیم.
Incorrect — تو requires second-person singular ـی, not first-person plural ـیم.
✅ تو این محله را بهتر میشناسی.
to in mahalle râ behtar mi-shenâsi.
You know this neighborhood better.
Key Takeaways
- The present stem is lexically selected and cannot always be guessed from the infinitive.
- Store new verbs as infinitive (present stem).
- Productive prefixes and personal endings attach around that stem.
- Historical alternations aid recognition, but exceptions such as رفت/رو and دید/بین must be learned.
- Standard and colloquial present forms are coherent register systems; do not splice them together randomly.
