Persian perception verbs can introduce a complete finite event: دیدم که در باز شد “I saw that the door opened,” شنیدم که برگشتی “I heard that you came back,” and حس کردم که زمین میلرزد “I felt that the ground was shaking.” Unlike English I saw her leave, Persian does not normally use a bare infinitive to express the perceived event. The event has its own finite verb, with tense, aspect, mood, and usually an understood subject.
The main structural challenge is distinguishing two objects. In دیدم که مریم وارد شد, the whole که clause is what was seen. In مریم را دیدم که وارد شد, مریم را is the specific person seen, and the following finite clause says what she did. That difference explains both the position of را and the interpretation.
Three frequent perception predicates
| Predicate | Core finite-complement reading | Typical extension | Register |
|---|---|---|---|
| دیدن | visually witness that an event occurs | come to realize from evidence | all registers |
| شنیدن | hear a sound or utterance | learn that something happened | all registers |
| حس کردن | physically feel a change | intuit or sense a situation | neutral; common in careful speech |
از پنجره دیدم که تاکسی جلوی ساختمان ایستاد.
az panjere didam ke tâksi jelow-e sâkhtemân istâd.
From the window, I saw that the taxi stopped in front of the building. (neutral standard; whole witnessed event)
شنیدم که فروشگاه سر کوچه را بستهاند.
shenidam ke forushgâh-e sar-e kuche râ baste-and.
I heard that they have closed the shop at the end of the street. (neutral; information received from others)
وقتی قطار رد شد، حس کردم که کف اتاق میلرزد.
vaqti qatâr rad shod, hes kardam ke kaf-e otâq mi-larzad.
When the train passed, I felt the floor of the room shaking. (neutral standard; physical perception)
With دیدن, the claim normally implies direct visual access. شنیدن که ... is less specific: it may mean that the speaker literally heard an event, but very often it means “hear/learn that ...” through somebody's report. حس کردن که ... likewise ranges from bodily sensation to a more abstract impression.
A whole-clause complement versus a را-marked participant
When the perceived content is a proposition, که + finite clause follows the perception verb. A clause does not take را merely because English calls it an “object clause.” Persian را marks a specific nominal direct object, not a finite proposition in this construction.
دیدم که چراغ اتاق ناگهان خاموش شد.
didam ke cherâgh-e otâq nâgahân khâmush shod.
I saw that the room light suddenly went out. (the clause is the perceived content)
If a specific participant is first established as the object of perception, that noun receives را. The following که clause then predicates an event of that participant. Persian grammar literature analyzes the exact syntactic relation in different ways, but for learners the robust generalization is clear: را belongs to the noun, while the second finite verb belongs to the event clause.
مریم را دیدم که با عجله از داروخانه بیرون آمد.
maryam râ didam ke bâ ajale az dârukhâne birun âmad.
I saw Maryam come out of the pharmacy in a hurry. (specific perceived participant plus finite event)
صدای همسایه را شنیدم که از راهرو کمک میخواست.
sedâ-ye hamsâye râ shenidam ke az râhru komak mi-khâst.
I heard the neighbor's voice calling for help from the corridor. (the perceived object is the voice; the clause identifies the ongoing utterance)
The را pattern is strongest when the noun is definite or otherwise specific: a named person, او, آن مرد, or a particular sound. For an indefinite participant, Persian can instead leave the subject inside the event clause: دیدم کسی وارد شد “I saw someone come in” (informal/neutral), with که often omitted in speech.
Simultaneity and the progressive
The tense of the complement is interpreted relative to the perception. A simple past can present a bounded event witnessed from beginning to endpoint: دیدم که افتاد “I saw that he fell.” A می past presents an event underway at the time of seeing: دیدم که میدوید “I saw that he was running.” The explicit past progressive داشت ... میکرد focuses even more sharply on an unfolding scene.
رضا را دیدم که کنار ایستگاه منتظر اتوبوس بود.
rezâ râ didam ke kenâr-e istgâh montazer-e otobus bud.
I saw Reza waiting for the bus by the station. (simultaneous state in a past scene)
از بالکن دیدیم که بچهها داشتند بادبادک هوا میکردند.
az bâlkon didim ke bachche-hâ dâshtand bâdbâdak havâ mi-kardand.
From the balcony, we saw that the children were flying a kite. (neutral spoken standard; explicit simultaneous progressive)
همان لحظه شنیدم که کسی داشت به در میکوبید.
hamân lahze shenidam ke kasi dâsht be dar mi-kubid.
At that very moment I heard someone pounding on the door. (neutral; auditory event in progress)
Do not copy English tense mechanically. English often uses an uninflected form after see/hear and a progressive translation elsewhere. Persian explicitly chooses between bounded افتاد, ongoing میافتاد, and focused progressive داشت میافتاد. For the two-verb progressive agreement pattern, see Past Progressive with داشتن.
Indicative, subjunctive, and negated perception
An affirmative report of an actually perceived event normally uses the indicative, because the speaker presents the event as part of reality. The subjunctive is possible in a narrower construction under negated perception or an indefinite search: ندیدم کسی وارد شود “I did not see anyone come in.” Here the event is not asserted as observed. This compact pattern is (formal/careful); everyday speech often uses ندیدم کسی وارد بشه (informal, regional: Tehran) or restructures the message.
در تمام فیلم ندیدم کسی به آن سؤال جواب بدهد.
dar tamâm-e film na-didam kasi be ân so'âl javâb be-dahad.
Throughout the film, I did not see anyone answer that question. (careful standard; non-asserted event after negated perception)
This does not mean “دیدن requires the subjunctive.” Affirmative دیدم که جواب داد presents an observed answer and takes the indicative. The licensing context—negation, nonoccurrence, or irrealis interpretation—matters more than the vocabulary item alone.
Short dialogue and register
— آرش را دیدی؟ — آره، دیدمش که داشت از پلهها بالا میرفت.
— ârash râ didi? — âre, didam-ash ke dâsht az pelle-hâ bâlâ mi-raft.
‘Did you see Arash?’ ‘Yeah, I saw him going up the stairs.’ (informal-neutral; آره and the object clitic are conversational)
The dialogue combines two strategies: ـش on دیدمش resumes the known object Arash, and the following finite clause describes the simultaneous event. Careful formal prose would normally avoid this conversational doubling and write آرش را دیدم که از پلهها بالا میرفت.
Common Mistakes
1. Copying the English bare infinitive
❌ سارا را دیدم از در بیرون رفتن.
Incorrect — رفتن is an infinitive; the perceived event needs a finite verb.
✅ سارا را دیدم که از ورودی پشتی بیرون رفت.
sârâ râ didam ke az vorudi-ye poshti birun raft.
I saw Sara leave through the back entrance.
2. Marking the whole که clause with را
❌ دیدم را که آسانسور رسید.
Incorrect — را cannot attach to دیدم or mark the following finite proposition.
✅ دیدم که آسانسور به طبقهی ما رسید.
didam ke âsânsur be tabaqe-ye mâ resid.
I saw that the elevator reached our floor.
3. Using the wrong aspect for an unfolding scene
⚠️ وقتی وارد شدم، دیدم او نامه نوشت.
vaqti vâred shodam, didam u nâme nevesht.
Grammatical with a bounded-event reading, but it does not present the writing as already underway when I entered.
✅ وقتی وارد شدم، دیدم او داشت یادداشت کوتاهی مینوشت.
vaqti vâred shodam, didam u dâsht yâddâsht-e kutâhi mi-nevesht.
When I came in, I saw that she was writing a short note.
4. Making the two progressive verbs disagree
❌ دیدیم که کارگرها داشت سقف را تعمیر میکردند.
Incorrect — plural کارگرها requires plural داشتند as well as میکردند.
✅ دیدیم که کارگرها داشتند سقف انبار را تعمیر میکردند.
didim ke kârgar-hâ dâshtand saqf-e anbâr râ ta'mir mi-kardand.
We saw that the workers were repairing the warehouse roof.
Key Takeaways
- A perceived event is normally a finite clause, not an English-style bare infinitive.
- که introduces the perceived proposition; را marks a specific perceived nominal participant.
- Simple past presents a bounded event, می past an ongoing background, and داشت ... میکرد a sharply focused simultaneous event.
- Affirmative perceived facts favor the indicative; subjunctive is licensed in narrower non-asserted contexts such as negated perception.
