شدن shodan: to Become | Farsi Grammar

شدن shodan presents a transition: something becomes cold, someone becomes a manager, a meeting finishes, or a document gets signed. That transition makes the verb central to three overlapping systems—ordinary change of state, intransitive compound predicates, and passive voice. It also appears impersonally in می‌شود “it is possible / one can.”

English often uses be, become, get, turn, or a verb with no visible auxiliary for the same situations. Persian learners therefore need more than the gloss “become.” The decisive question is whether شدن introduces a change, supplies the intransitive partner of a compound, or carries the inflection of a passive predicate.

Principal parts

Form	Persian	Reading	Use
infinitive	شدن	shodan	dictionary form
past stem	شد	shod-	شدم، تمام شد
present stem	شو	shav- before endings	می‌شوم، بشود
past participle	شده	shode	شده‌ام، باز شده است
imperative	بشو؛ بشوید	besho; beshavid	often used inside a compound
negative imperative	نشو؛ نشوید	nasho; nashavid	“do not become/get”

Written شو is pronounced shav- before vowel-initial endings: می‌شوم mi-shavam, بشویم be-shavim. In the singular imperative بشو, final و is the vowel o: besho. This is lexical allomorphy, not optional pronunciation.

High-value paradigm

Person	Present indicative	Simple past	Present perfect	Present subjunctive
I	می‌شوم	شدم	شده‌ام	بشوم
you (sg.)	می‌شوی	شدی	شده‌ای	بشوی
he/she/it	می‌شود	شد	شده است	بشود
we	می‌شویم	شدیم	شده‌ایم	بشویم
you (pl./polite)	می‌شوید	شدید	شده‌اید	بشوید
they	می‌شوند	شدند	شده‌اند	بشوند

Negation replaces the leftmost affirmative marker: نمی‌شوم، نشدم، نشده‌ام، نشوم. In compounds, subjunctive بـ can be omitted: both ممکن است باز بشود and ممکن است باز شود occur, with the shorter form especially common in careful writing.

هوا تا غروب خیلی سردتر می‌شود.

havâ tâ ghorub kheyli sard-tar mi-shavad.

خواهرم بعد از چند سال مدیر بخش شد.

khâhar-am ba'd az chand sâl modir-e bakhsh shod.

My sister became the department manager after several years. (neutral standard; new role)

چای سرد شده است؛ دوباره گرمش می‌کنم.

chây sard shode ast; dobâre garm-ash mi-konam.

The tea has gone cold; I'll warm it up again. (neutral standard; perfect result)

ممکن است جاده تا ظهر باز شود.

momken ast jâdde tâ zohr bâz shavad.

The road may reopen by noon. (formal-neutral; prefixless compound subjunctive)

💡

The subject of lexical شدن is normally the participant that undergoes the change. To add an external causer, Persian often switches to the paired کردن predicate.

Change-of-state pairs with کردن

Many adjective-based and noun-based predicates form a useful valency pair: خاموش کردن “turn something off” versus خاموش شدن “go out / turn off,” گم کردن “lose” versus گم شدن “get lost,” and تمام کردن “finish something” versus تمام شدن “come to an end.” Only the transitive کردن member takes the affected object with را.

باد پنجره را باز کرد، اما چند دقیقه بعد پنجره خودبه‌خود بسته شد.

bâd panjare râ bâz kard, ammâ chand daqiqe ba'd panjare khod-be-khod baste shod.

The wind opened the window, but a few minutes later the window closed by itself. (neutral standard; transitive کردن versus spontaneous شدن)

با همسایه‌های جدیدمان خیلی زود آشنا شدیم.

bâ hamsâye-hâ-ye jadid-emân kheyli zud âshenâ shodim.

We got acquainted with our new neighbors very quickly. (neutral standard; آشنا شدن با)

The preposition belongs to the whole predicate: با کسی آشنا شدن, از چیزی مطمئن شدن, به چیزی تبدیل شدن. English become does not predict these frames, so dictionaries should be consulted at the compound level.

Passive auxiliary

To passivize a simple transitive verb, Persian places its past participle before an inflected form of شدن. Thus نوشتن supplies passive نوشته شد, and فروختن supplies فروخته می‌شود. The patient becomes the grammatical subject, while شدن carries tense, negation, and agreement.

این دارو فقط با نسخه فروخته می‌شود.

in dâru faqat bâ noskhe forukhte mi-shavad.

This medicine is sold only with a prescription. (formal-neutral; present passive)

نتیجه‌ی آزمایش هنوز برای من فرستاده نشده است.

natije-ye âzmâyesh hanuz barâ-ye man ferestâde na-shode ast.

The test result has not been sent to me yet. (formal-neutral; negative perfect passive)

Not every X + شدن is syntactic passive. چراغ خاموش شد can simply report an intransitive change without an implied agent. Passive with شدن: First Pattern gives the event and agent diagnostics.

Impersonal possibility with می‌شود

Clause-initial می‌شود can mean “it is possible / one can,” followed by an infinitive or a subjunctive clause. It does not agree with the logical person who might act; third singular is impersonal.

می‌شود این صندلی را کمی جلوتر برد؟

mi-shavad in sandali râ kami jelow-tar bord?

Could this chair be moved a little farther forward? (polite neutral; impersonal possibility + short infinitive)

Negative نمی‌شود ranges from practical impossibility to prohibition: اینجا نمی‌شود پارک کرد can mean “you cannot park here.” Context, not the verb alone, decides whether a rule or physical obstacle is involved.

Commands and Tehran speech

Bare “become!” is rarely useful, but compounds make the imperative natural: آماده شو، ساکت شو، عصبانی نشو. Everyday Tehran reduces the present paradigm to می‌شم، می‌شی، می‌شه، می‌شیم، می‌شین، می‌شن (informal: Tehran). Standard prose retains می‌شوم، می‌شود، می‌شوند.

آماده شو؛ تاکسی پایین منتظر است.

âmâde sho; tâksi pâyin montazer ast.

Get ready; the taxi is waiting downstairs. (informal command)

— چی شد؟ چرا چراغا خاموش شدن؟ — برق رفت؛ الان درست میشه.

— chi shod? cherâ cherâghâ khâmush shodan? — barq raft; alân dorost mishe.

— What happened? Why did the lights go out? — The power went out; it'll be fixed now. (informal: Tehran)

💡

Colloquial میشه can mean “it becomes,” “it gets done,” or impersonal “it is possible.” Recover the surrounding predicate before translating it.

Common Mistakes

1. Using شدن for a stable identity

❌ من الان دانشجو می‌شوم.

Incorrect for ‘I am a student now’ — می‌شوم means ‘I become/am becoming.’

✅ من الان دانشجو هستم و سال بعد فارغ‌التحصیل می‌شوم.

man alân dâneshju hastam-o sâl-e ba'd fâregh-ot-tahsil mi-shavam.

I am a student now and will graduate next year.

2. Giving intransitive شدن a direct object

❌ من اتاق را سرد شدم.

Incorrect — شدن makes the changing participant the subject; a causer needs سرد کردن.

✅ من پیش از خواب اتاق را کمی خنک کردم.

man pish az khâb otâq râ kami khonak kardam.

I cooled the room a little before going to sleep.

3. Omitting the lexical participle in a passive

❌ این نامه دیروز می‌شود.

Incorrect for ‘this letter was written yesterday’ — شدن alone does not supply the lexical event.

✅ این نامه دیروز نوشته شد.

in nâme diruz neveshte shod.

This letter was written yesterday.

4. Mixing a Tehran form with polite standard agreement

❌ شما چه ساعتی آماده می‌شه؟

Incorrect — می‌شه carries third-person singular agreement and cannot agree with شما.

✅ شما چه ساعتی آماده می‌شوید؟

shomâ che sâ'ati âmâde mi-shavid?

What time will you be ready? (polite standard)

5. Leaving می‌ detached

❌ این صفحه خیلی دیر باز می شود.

Incorrect standard orthography — imperfective می‌ attaches to شود with a ZWNJ.

✅ این صفحه روی گوشی من خیلی دیر باز می‌شود.

in safhe ru-ye gushi-ye man kheyli dir bâz mi-shavad.

This page opens very slowly on my phone.

Key Takeaways

Memorize شدن — شد — شو — شده and pronounce شو as shav- before endings.
Lexical شدن makes the changing participant the subject; paired کردن often introduces a causer.
Passive predicates keep the lexical participle and inflect شدن; many compounds are instead ordinary intransitive changes.
Impersonal می‌شود expresses possibility, while Tehran میشه represents several standard structures in speech.
