Perception plus را and که | Farsi Grammar

Persian can combine a perception verb with both a direct-object noun phrase and a finite که clause: مریم را دیدم که داشت از پله‌ها پایین می‌آمد “I saw Maryam coming down the stairs.” مریم را is the object of دیدم; the following clause tells what Maryam was doing at the moment of perception. The marker را therefore belongs to the perceived participant, not to the event clause.

English usually uses an object plus an -ing form (I saw Maryam coming). Persian instead gives the perceived scene a finite verb with tense, aspect, and agreement. This lets Persian distinguish seeing a participant in an event from merely learning that a proposition is true.

Two structures that English often blurs

Persian frame	What is perceived	Typical interpretation
NP را + دیدن/شنیدن + که + finite clause	a participant during an event	I saw/heard NP doing something
دیدن/شنیدن + که + complete clause	a fact or whole situation	I saw/realized or heard that P
NP را + دیدن/شنیدن	the participant or stimulus alone	I saw/heard NP

مریم را دیدم که داشت از پله‌ها پایین می‌آمد.

Maryam râ didam ke dâsht az pelle-hâ pâyin mi-âmad.

I saw Maryam coming down the stairs. (neutral; participant plus simultaneous event)

دیدم که مریم از پله‌ها پایین می‌آمد.

didam ke Maryam az pelle-hâ pâyin mi-âmad.

I saw/realized that Maryam was coming down the stairs. (neutral; the whole proposition is the complement)

The first construction entails direct visual contact with Maryam. The second can still report direct observation, but its syntax packages the whole proposition as what the speaker came to see or understand. Context can narrow the difference; the word order nevertheless gives the reader a different starting parse.

💡

Locate را first. If it follows a participant before the perception verb, that participant is the object of perception; که then opens a finite scene predicated of that participant.

Why progressive aspect is frequent

Perception often overlaps with an unfolding event. Persian therefore commonly uses می‌ـ or داشت + می‌ـ in the که clause. The two verbs need not share tense morphology: the matrix verb locates the perception, while the embedded aspect describes the scene visible or audible then.

بچه‌ها را از پنجره دیدیم که در حیاط بازی می‌کردند.

bachche-hâ râ az panjare didim ke dar hayât bâzi mi-kardand.

We saw the children from the window playing in the yard. (neutral; ongoing simultaneous scene)

همسایه‌مان را شنیدم که داشت آرام تلفنی حرف می‌زد.

hamsâye-mân râ shenidam ke dâsht ârâm telefoni harf mi-zad.

I heard our neighbor speaking quietly on the phone. (neutral; audible participant and ongoing action)

The progressive is typical, not compulsory. A bounded event can use the simple past when the observer perceives it as a whole: دیدم که چراغ خاموش شد “I saw that the light went out.” That is more naturally a complete clausal complement because a light's going out, rather than an independently perceived participant, is the salient event.

Agreement identifies the understood participant

After NP را دیدم که ..., the subject of the که clause is commonly unspoken and recovered from the perceived NP. Its verb agrees with that participant: plural بچه‌ها را ... که بازی می‌کردند, singular همسایه‌مان را ... که حرف می‌زد. An overt subject is possible when the scene has a different actor, but then the construction no longer has the simple English “NP doing” relation.

دو کارگر را دیدم که جعبه‌ی بزرگی را جابه‌جا می‌کردند.

do kârgar râ didam ke ja'be-ye bozorgi râ jâbe-jâ mi-kardand.

I saw two workers moving a large box. (neutral; plural agreement identifies the workers)

سارا را دیدم که برادرش جلوی در منتظرش بود.

Sârâ râ didam ke barâdar-ash jelow-ye dar montazer-ash bud.

I saw Sara while her brother was waiting for her by the door. (neutral; the embedded subject is overt and different)

In the second example, برادرش is the subject of بود and final ـش in منتظرش refers to Sara. The که clause describes the circumstance in which the speaker saw her; it does not predicate “waiting” of Sara. This is why agreement and pronoun reference matter more than the nearest English translation.

Object clitics as an alternative to NP را

An identifiable perceived participant can be expressed by an object clitic on دیدن or شنیدن: دیدمش که ...، شنیدمشان که .... The clitic replaces the full direct-object expression; do not retain NP را as a second copy unless a special clitic-doubling construction is intended.

دیدمش که کنار ایستگاه دنبال تاکسی می‌گشت.

didam-ash ke kenâr-e istgâh donbâl-e tâksi mi-gasht.

I saw her looking for a taxi near the station. (neutral conversation; object clitic)

شنیدمشان که درباره‌ی نتیجه بحث می‌کردند.

shenidam-eshân ke darbâre-ye natije bahs mi-kardand.

I heard them discussing the result. (careful standard; plural object clitic)

Full او را/آن‌ها را is clearer when participants are being contrasted or introduced. Clitics are lighter and expect an accessible referent. See Differential Object Marking with را and object clitics.

💡

Use either a full accessible object plus را or an object clitic according to discourse weight. The following finite clause retains its own subject agreement in both patterns.

شنیدن: direct sound versus reported information

With شنیدن, the contrast is especially useful. صدای نرگس را شنیدم که ... reports direct auditory perception. Bare شنیدم که ... often means “I heard/was told that ...,” without claiming that the speaker directly heard the described event.

صدای نرگس را شنیدم که از اتاق کناری می‌آمد.

sedâ-ye Narges râ shenidam ke az otâq-e kenâri mi-âmad.

I heard Narges's voice coming from the next room. (neutral; direct auditory evidence)

شنیدم که نرگس برای اجرای تازه‌ای تمرین می‌کند.

shenidam ke Narges barâ-ye ejrâ-ye tâze-i tamrin mi-konad.

I heard that Narges is rehearsing for a new performance. (neutral; reported information)

The second sentence may come from another person's report. Persian does not force an English-style evidential label, but the presence or absence of a direct perceived object strongly guides the inference.

Parsing a potentially ambiguous noun

مردی را دیدم که می‌دوید can be analyzed as perceiving a man in the act of running, while it also resembles “I saw a man who was running,” with a relative clause modifying مردی. In practice the two readings describe nearly the same scene. Aspect, prosody, and later discourse decide whether the clause mainly identifies the man or presents his action.

Writers can remove ambiguity by choosing a definite participant for the perception construction or by making identification explicit: مردی را که کت آبی داشت دیدم has را before the relative clause and means “I saw the man who had a blue coat.” The relative-clause resumption page develops that pattern.

Common Mistakes

1. Treating را as a clause marker

❌ دیدم را که مریم می‌دوید.

Incorrect — را follows the perceived noun phrase; it cannot mark a finite که clause.

✅ مریم را دیدم که به‌طرف ایستگاه می‌دوید.

Maryam râ didam ke be-taraf-e istgâh mi-david.

I saw Maryam running toward the station.

2. Copying an English bare participle

❌ بچه‌ها را دیدم بازی کردن در حیاط.

Incorrect for the ordinary perception frame — a bare infinitive does not encode the subject agreement and aspect supplied by the finite که clause.

✅ بچه‌ها را دیدم که در حیاط بازی می‌کردند.

bachche-hâ râ didam ke dar hayât bâzi mi-kardand.

I saw the children playing in the yard.

3. Mismatching embedded agreement

❌ دوستم را دیدم که به خانه می‌رفتند.

Incorrect — singular دوستم is the understood embedded subject, so the verb must be singular می‌رفت.

✅ دوستم را دیدم که به خانه می‌رفت.

dust-am râ didam ke be khâne mi-raft.

I saw my friend going home.

4. Duplicating and mismatching the object

❌ مریم را دیدمشان که وارد شد.

Incorrect — plural ـشان cannot resume singular مریم, and the neutral construction does not need a second copy of the full object.

✅ مریم را دیدم که وارد ساختمان شد.

Maryam râ didam ke vâred-e sâkhtemân shod.

I saw Maryam enter the building.

Key Takeaways

In NP را دیدم که ..., را marks the perceived participant; the finite که clause presents that participant's simultaneous event.
Progressive aspect is frequent because perception overlaps with an unfolding scene, but bounded events can use perfective aspect.
Embedded agreement normally recovers the perceived participant as its unspoken subject.
An object clitic such as دیدمش can replace the full NP را expression.
Bare شنیدم که P often reports information, whereas a direct object plus را foregrounds an actually heard stimulus or participant.
