Preposition Drop and Fusion in Speech | Farsi Grammar

Spoken Tehran Persian can make a destination or participant much more compact than formal written Persian. A highly recoverable goal may appear without overt به—میرم خونه “I'm going home”—while a pronominal complement may fuse with its preposition—بهش، باهاش، برات “to him/her, with him/her, for you.” These are two related pressures toward compact speech, but they are not one unrestricted deletion rule.

Goal preposition omission is (informal, regional: Tehran) and depends on a conventional motion expression plus an easily interpreted destination. Preposition–clitic forms have a wider range: برایم، برایش، ازش can be ordinary compact Persian, while برات، باهاش have a clearly conversational shape. Edited prose generally restores the full prepositional structure or selects its standard fused counterpart.

Two Patterns, Not One

Meaning	Standard/careful	Conversational Iranian	Analysis
I am going home	به خانه می‌روم	میرم خونه	recoverable goal; به omitted
I went to work	به محل کار رفتم	رفتم سر کار	conventional destination phrase
I told him/her	به او گفتم	بهش گفتم	به remains; pronoun is clitic
with him/her	با او	باهاش	colloquial fused family with ها
for you	برای تو	برات	reduced host plus clitic

💡

In بهش and باهاش, the relation has not vanished: به still means “to,” and colloquial باهاـ still means “with.” The clitic replaces an unstressed pronoun, not the preposition.

Recoverable Goals without به

Motion verbs such as رفتن، آمدن، رسیدن can occur with a bare destination when the goal relation is obvious and the destination is conventional in the situation. Home, work, school, a city, or a meeting are common. The bare phrase answers “where to?”, not “where?” in a static clause.

من دیگه میرم خونه.

man dige mi-ram khune.

I'm heading home now. (informal, regional: Tehran; recoverable goal)

صبح زود رفتیم سر کار.

sobh zud raftim sar-e kâr.

We went to work early in the morning. (informal; conventional destination phrase)

آخر هفته می‌ریم شمال.

âkhar-e hafte mi-rim shomâl.

We're going north for the weekend. (informal Iranian; conventional travel destination)

کی می‌رسین فرودگاه؟

key mi-rasin forudgâh?

When will you get to the airport? (informal, regional: Tehran; polite/plural)

The listener infers goal from the motion predicate. English also says “go home” without to, but extends that privilege to far fewer nouns: English requires go to school, whereas Persian conversation can say رفتم مدرسه. Do not infer that Persian lacks prepositions; this is a licensed goal construction.

When به Should Remain

An overt به is favored when the relation could be misunderstood, the destination is structurally heavy or contrastive, the verb does not conventionally license a bare goal, or the register is careful. It is also required inside many lexical and abstract combinations. Compare a routine destination with an explicitly contrasted one.

امروز میرم دانشگاه، نه کتابخونه.

emruz mi-ram dâneshgâh, na ketâbkhune.

Today I'm going to the university, not the library. (informal; both goals remain recoverable)

برای مصاحبه به ساختمان مرکزی رفتم.

barâ-ye mosâhebe be sâkhtemân-e markazi raftam.

I went to the central building for the interview. (neutral/careful; explicit and modified goal)

این تغییر به کیفیت کار آسیب می‌زنه.

in taghyir be keyfiyyat-e kâr âsib mi-zane.

This change harms the quality of the work. (conversational grammar; lexical به is retained)

The last به is not a destination marker waiting to disappear. It is selected by آسیب زدن به “to damage.” Verb-governed and abstract relations must be learned with their predicates. Movement versus Location establishes the core spatial contrast.

به plus a Pronominal Clitic

Instead of به من، به تو، به او, speech commonly uses بهم، بهت، بهش. The attached element is an unstressed, contextually accessible pronoun. It can refer to a person, animal, object, or proposition as context permits; Persian does not encode gender in ـش.

آدرس رو بهش فرستادم.

âdres ro beh-esh ferestâdam.

I sent him/her the address. (informal; به is retained before a clitic)

وقتی رسیدی، بهم خبر بده.

vaqti residi, beh-em khabar bede.

Let me know when you arrive. (informal)

بهتون گفتن جلسه لغو شده؟

beh-etun goftan jalase laghv shode?

Did they tell you that the meeting was canceled? (friendly polite or plural speech)

The person/number system is the ordinary pronominal clitic set. The preposition supplies the recipient relation; the clitic supplies its participant. A full pronoun remains natural for contrast: به من گفت، نه به تو “He/she told me, not you.”

باهاش and the Colloquial با Family

With با, colloquial Iranian Persian normally uses the expanded shapes باهام، باهات، باهاش، باهامون، باهاتون، باهاشون. These should be learned as a family; simply attaching ـش to با does not produce the ordinary intended form.

دیشب باهاش حرف زدم.

dishab bâhâsh harf zadam.

I talked with him/her last night. (informal Iranian)

اگه می‌خوای، باهامون بیا.

age mi-khây, bâhâmun biyâ.

If you want, come with us. (informal Iranian)

فردا لپ‌تاپت رو باهات بیار.

fardâ laptop-at ro bâhât biyâr.

Bring your laptop with you tomorrow. (informal Iranian)

💡

The ها in باهاش is part of this conventional colloquial series; it is not plural ها. باهاش can refer to one person or one thing.

برات, براش, and Register

Standard برای تو / برایت and برای او / برایش have conversational counterparts برات and براش. Tehran speech also uses واست، واسش after colloquial واسه. The shorter برات is compact but can remain perfectly courteous in a friendly context.

یه تیکه کیک برات نگه داشتم.

ye tikke keyk barât negah dâshtam.

I saved you a piece of cake. (informal Iranian)

براش توضیح دادم که چرا دیر رسیدیم.

barâsh towzih dâdam ke cherâ dir residim.

I explained to him/her why we arrived late. (informal Iranian)

این صندلی رو واست کنار گذاشتم.

in sandali ro vâsat kenâr gozâshtam.

I set this chair aside for you. (informal, regional: Tehran)

In formal prose, choose برای شما، برایتان rather than transcribing براتون. For the broader paradigm and contrastive full-pronoun rule, see Clitics on Prepositions.

Fusion Is Not Available with a Full Noun

A pronominal clitic replaces a recoverable pronoun; it does not attach to an overt lexical noun that expresses the same participant. Say به علی گفتم or بهش گفتم, not an invented doubling. Likewise, با دوستم “with my friend” contains a possessive clitic on دوست, whereas باهاش contains the complement of با. Similar-looking endings may have different syntactic hosts.

موضوع رو به علی گفتم، نه به مریم.

mowzu' ro be Ali goftam, na be Maryam.

I told Ali about it, not Maryam. (informal; full nouns carry contrast)

موضوع رو بهش گفتم؛ خودش به مریم میگه.

mowzu' ro beh-esh goftam; khod-esh be Maryam mi-ge.

I told him/her about it; he/she will tell Maryam. (informal; clitic refers to an accessible participant)

Object clitics also need to be kept separate. دیدمش means “I saw him/her”: ـش is the direct object of دیدن. بهش گفتم means “I told him/her”: ـش is the complement of به. Compact sound alone does not determine grammatical function.

A Connected Exchange

— فردا میری شرکت؟ — آره، اول میرم بانک، بعد میرم شرکت. — این پاکت رو هم برام می‌بری؟ — بده؛ بهشون تحویل میدم.

— fardâ mi-ri sherkat? — âre, avval mi-ram bânk, ba'd mi-ram sherkat. — in pâkat ro ham barâm mi-bari? — bede; beh-eshun tahvil mi-dam.

— Are you going to the office tomorrow? — Yeah, first I'm going to the bank, then the office. — Will you take this envelope for me too? — Give it to me; I'll hand it to them. (informal Tehran; bare goals and fused prepositions form one system)

Common Mistakes

1. Dropping به from any phrase that contains it

❌ این موضوع کیفیت کار آسیب می‌زنه.

Malformed for the intended meaning — lexical آسیب زدن به requires the preposition.

✅ این موضوع به کیفیت کار آسیب می‌زنه.

in mowzu' be keyfiyyat-e kâr âsib mi-zane.

This issue harms the quality of the work. (conversational grammar with required به)

2. Treating بهش as preposition deletion

Do not analyze بهش as preposition deletion. Both the letters به and the recipient relation remain in the compact form:

✅ بهش گفتم فردا زودتر بیاد.

beh-esh goftam fardâ zud-tar biyâd.

I told him/her to come earlier tomorrow. (informal; به + pronominal clitic)

3. Attaching a clitic to a co-referential full noun

❌ به علیش گفتم زنگ بزنه.

Malformed in the intended neutral reading — علی and ـش cannot both be the same prepositional complement.

✅ به علی گفتم زنگ بزنه.

be Ali goftam zang bezane.

I told Ali to call. (informal syntax with an overt noun complement)

4. Mixing a spoken compact form into official prose

⚠️ نتیجه‌ی درخواست براتون ارسال خواهد گردید.

natije-ye darkhâst barâtun ersâl khâhad gardid.

The result of the application will be sent to you. Interpretable, but colloquial براتون clashes sharply with formal خواهد گردید.

✅ نتیجه‌ی درخواست برای شما ارسال خواهد شد.

natije-ye darkhâst barâ-ye shomâ ersâl khâhad shod.

The result of the application will be sent to you. (formal written standard)

5. Assuming a bare destination is always a static location

Do not give bare خونه one fixed locative meaning. After میرم it is a goal; a static location requires a locative construction. The contrast is visible within one sentence:

✅ من میرم خونه، ولی خواهرم الان خونه‌ست.

man mi-ram khune, vali khâhar-am alân khune-st.

I'm going home, but my sister is at home now. (informal; goal followed by static location)

Key Takeaways

Bare goals such as میرم خونه are licensed by motion meaning and a recoverable destination; Persian has not generally deleted its prepositions.
بهش، باهاش، برات contain pronominal clitics. The prepositional relation remains inside the compact form.
Keep overt به with lexically selected and abstract relations, and favor it with heavy or formal goal phrases.
A clitic replaces an accessible pronoun; use a full noun or pronoun for contrast and never double it as به علیش.
Align goal omission, fused clitics, verb shapes, object رو, and surrounding vocabulary into one coherent register.
