Subject Omission and Verb Agreement | Farsi Grammar

Persian usually omits a subject pronoun when the context and verb ending identify it. می‌روم already means “I go/am going,” so من is unnecessary unless “I” is contrasted or emphasized. English normally requires a subject word; Persian lets agreement do that work.

This is called subject omission or pro-drop. It is normal in conversation, formal prose, messages, and narration—not a shortcut or slang feature. Natural use depends on two things: the verb must have the right person-and-number form, and the listener must be able to recover who the subject is.

Six persons in the verb ending

Person	Pronoun	Written present suffix	Example
I	من	ـم	می‌نویسم
you (singular informal)	تو	ـی	می‌نویسی
he/she/it	او / آن	ـد	می‌نویسد
we	ما	ـیم	می‌نویسیم
you (plural/polite)	شما	ـید	می‌نویسید
they	آن‌ها	ـند	می‌نویسند

The endings identify grammatical person and number, not a specific person by name. می‌نویسد tells us “third-person singular,” but only context tells us whether the writer is Leila, Reza, the teacher, or a machine. Persian agreement also does not encode gender.

هر شب چند خط در دفترم می‌نویسم.

har shab chand khat dar daftar-am mi-nevisam.

Every night I write a few lines in my notebook. (neutral standard; ـم identifies ‘I’)

فردا با ما به نمایشگاه می‌آیید؟

fardâ bâ mâ be namâyeshgâh mi-âyid?

Are you coming to the exhibition with us tomorrow? (polite/plural standard; شما omitted)

💡

Read the ending before adding a pronoun. If ـم، ـی، ـیم، ـید already identifies the participant and context supplies the referent, omission is the neutral choice.

Continuing the same subject

Subject omission is especially natural across a sequence of actions by the same person. State the subject once if needed, then let matching endings maintain it. Repeating the pronoun before every verb can sound as if each repetition is a new contrast.

مریم ساعت شش بیدار شد، صبحانه خورد و از خانه بیرون رفت.

Maryam sâ'at-e shesh bidâr shod, sobhâne khord va az khâne birun raft.

Maryam woke up at six, ate breakfast, and left home. (neutral narration; subject stated once)

به ایستگاه رسیدیم، بلیت خریدیم و سوار قطار شدیم.

be istgâh residim, belit kharidim va savâr-e qatâr shodim.

We arrived at the station, bought tickets, and boarded the train. (neutral standard; ـیم maintains ‘we’)

English normally needs an overt subject in a finite clause, though coordinated verbs can share one. Persian goes further: a sentence can begin with رسیدیم “we arrived” and leave “we” entirely unspoken because the ending identifies it. The detailed ending system is reviewed on Personal Endings across Tenses.

When the subject should be expressed

Use an overt noun or pronoun when it answers “who?”, contrasts participants, corrects an assumption, introduces a new participant, or prevents ambiguity. Pronouns are not forbidden; they carry discourse work.

من ماشین را می‌برم؛ تو با مترو برو.

man mâshin râ mi-baram; to bâ metro berow.

I'll take the car; you go by metro. (neutral conversation; contrastive subjects)

چه کسی پنجره را باز کرد؟ من باز کردم.

che kasi panjare râ bâz kard? man bâz kardam.

Who opened the window? I did. (neutral conversation; focused answer)

نرگس با لیلا حرف زد. بعد لیلا به مدیر تلفن کرد.

Narges bâ Leylâ harf zad. ba'd Leylâ be modir telefon kard.

Narges spoke with Leila. Then Leila called the manager. (neutral standard; repeated name prevents a wrong subject reading)

The last sentence has two possible third-person women in the discourse. Bare بعد به مدیر تلفن کرد would not tell the reader which one called. The verb ending marks singular but cannot choose between them.

💡

Agreement answers “which person and number?”; context answers “which individual?” Express the subject whenever two possible third-person referents compete.

The special shape of the simple past

Most past forms have endings: رفتم، رفتی، رفتیم، رفتید، رفتند. Third-person singular simple past has no overt ending: رفت “he/she/it went.” Context is therefore especially important, though an overt noun is not automatically required.

علی دیر رسید، چون اتوبوس وسط راه خراب شد.

Ali dir resid, chun otobus vasat-e râh kharâb shod.

Ali arrived late because the bus broke down on the way. (neutral standard; two overt third-singular subjects)

در را بست و کلید را روی میز گذاشت.

dar râ bast va kelid râ ru-ye miz gozâsht.

He or she closed the door and put the key on the table. (neutral narrative; subject understood from earlier context)

Persian does not need a gendered he/she pronoun. When gender or identity matters, use a name, noun phrase, or additional context.

Compound verbs and copular predicates

In a compound predicate, subject agreement appears on the light verb: تصمیم گرفتم “I decided,” کار می‌کنند “they work.” The nonverbal element does not change. In a present copular sentence, the short copula itself marks person: خسته‌ام “I am tired,” آماده‌ایم “we are ready.”

هنوز تصمیم نگرفته‌ایم؛ فردا خبر می‌دهیم.

hanuz tasmim nagerefte-im; fardâ khabar mi-dehim.

We have not decided yet; we will let you know tomorrow. (neutral standard; ‘we’ encoded twice)

برای شروع آماده‌ام.

barâ-ye shoru' âmâde-am.

I am ready to begin. (neutral standard; copular ـام identifies ‘I’)

Standard and Tehran agreement

Everyday Tehran speech (informal, regional: Tehran) reduces some endings: می‌ره for standard می‌رود, می‌رن for می‌روند, and خسته‌ان for خسته‌اند. Subject omission remains normal in both registers. Keep a sentence internally consistent rather than attaching a standard ending to a colloquial stem.

— کجایین؟ — توی راهیم؛ ده دقیقه دیگه می‌رسیم.

— kojâyin? — tu-ye râhim; dah daqiqe dige mi-resim.

— Where are you? — We're on the way; we'll arrive in ten minutes. (informal, regional: Tehran; omitted شما and ما)

Common Mistakes

1. Repeating an English-style subject

❌ من رسیدم و من نشستم و من غذا سفارش دادم.

Incorrect as neutral continuity — repeated من gives an unintended contrast at each step.

✅ رسیدم، کنار پنجره نشستم و غذا سفارش دادم.

residam, kenâr-e panjare neshashtam va ghazâ sefâresh dâdam.

I arrived, sat by the window, and ordered food.

2. Mismatching the subject and ending

❌ ما فردا به تبریز می‌روم.

Incorrect — ما requires first-person plural می‌رویم.

✅ ما فردا صبح به تبریز می‌رویم.

mâ fardâ sobh be Tabriz mi-ravim.

We are going to Tabriz tomorrow morning.

3. Omitting a subject when two referents compete

❌ مینا سارا را دید و بعد او به خانه رفتند.

Incorrect — singular او cannot take plural رفتند; use a named singular subject to identify who went.

✅ مینا سارا را دید و بعد سارا به خانه رفت.

Minâ Sârâ râ did va ba'd Sârâ be khâne raft.

Mina saw Sara, and then Sara went home.

4. Mixing standard and colloquial agreement

❌ شما فردا میاییدین؟

Incorrect — this stacks two second-plural endings on one verb.

✅ شما فردا برای ناهار می‌آیید؟

shomâ fardâ barâ-ye nâhâr mi-âyid?

Are you coming for lunch tomorrow? (polite standard)

Key Takeaways

Persian normally omits a recoverable subject because the finite ending marks person and number.
Omission is standard across registers; overt pronouns express contrast, focus, correction, or clarity.
Agreement cannot identify a particular third-person referent or gender.
In compound verbs, agreement belongs to the light verb; in present copular clauses, the copula marks person.
