In فکر نمیکنم که بیاید “I don't think he or she will come,” negation is grammatically attached to فکر میکنم but is usually interpreted inside the proposition: “I think that he or she will not come.” This mismatch is called negative raising. It is especially natural with weak belief predicates, where matrix negation also softens the speaker's commitment.
Negative raising is not automatic movement, and the two possible placements are not perfect synonyms. فکر نمیکنم بیاید presents a cautious rejection of a positive possibility; فکر میکنم نمیآید asserts a negative prediction more directly. Register, mood, prosody, and polarity items reveal the difference.
The central contrast
| Form | Typical interpretation | Complement form | Pragmatic force |
|---|---|---|---|
| فکر نمیکنم که بیاید | I do not believe that he or she will come; often, I believe that he or she will not | subjunctive | cautious, softened |
| فکر میکنم که نمیآید | I believe that he or she will not come | indicative | more committed prediction |
| نمیدانم که میآید یا نه | I do not know whether he or she is coming | interrogative alternative | genuine uncertainty; no raising |
| نمیخواهم که بیاید | I do not want him or her to come | subjunctive | desire, not belief |
English has the same familiar contrast between “I don't think she is coming” and “I think she isn't coming.” Persian likewise favors the matrix-negative version in polite disagreement, but Persian more clearly shows the nonasserted status of the complement through subjunctive باشد، بیاید، بتواند.
فکر نمیکنم این قطار تا ساعت هشت برسد.
fekr nemi-konam in qatâr tâ sâ'at-e hasht be-rasad.
I don't think this train will arrive by eight. (neutral conversation; matrix negation and subjunctive complement)
فکر میکنم این قطار تا ساعت هشت نمیرسد.
fekr mi-konam in qatâr tâ sâ'at-e hasht nemi-rasad.
I think this train won't arrive by eight. (neutral; embedded negation and firmer prediction)
The first leaves more room for correction; the second commits the speaker to a negative timetable prediction. Neither construction mathematically entails the other in every context: not believing P can reflect insufficient evidence rather than belief in not-P.
Why the complement tends toward the subjunctive
After matrix فکر نمیکنم, the complement is not presented as an established fact. Standard Persian therefore commonly uses the present subjunctive, especially for future, modal, or evaluative predicates.
فکر نمیکنم این راهحل در عمل مؤثر باشد.
fekr nemi-konam in râh-hal dar amal mo'asser bâshad.
I don't think this solution will be effective in practice. (formal-neutral; softened evaluation)
بعید میدانم دولت بتواند هزینه را در یک سال جبران کند.
ba'id mi-dânam dowlat be-tavânad hazine râ dar yek sâl jobrân konad.
I consider it unlikely that the government can recover the cost within one year. (formal; negative-like evaluation licensing a subjunctive)
Colloquial Tehran Persian often omits که and reduces the matrix verb, but keeps the same scope contrast:
فکر نکنم امشب بیاد.
fekr na-konam emshab biyâd.
I don't think he'll come tonight. (informal, regional: Tehran; reduced matrix expression)
فکر نکنم is formally shaped like a subjunctive negative but functions as a conventional first-person hedge in speech. Formal prose prefers فکر نمیکنم که ... or a more impersonal expression such as بعید است که ....
Matrix negation is not always raised
Some contexts literally deny the act of thinking rather than the complement. Contrastive stress, correction, or a continuation can force that reading.
من فکر نمیکنم؛ میدانم که این رقم اشتباه است.
man fekr nemi-konam; mi-dânam ke in raqam eshtebâh ast.
I don't think it; I know that this figure is wrong. (contrastive; matrix negation is literal)
نمیگویم که گزارش بیارزش است؛ میگویم شواهدش کافی نیست.
nemi-guyam ke gozâresh bi-arzesh ast; mi-guyam shavâhed-ash kâfi nist.
I am not saying the report is worthless; I am saying its evidence is insufficient. (formal; metalinguistic denial, not negative raising)
The continuation identifies what is denied: the speech act نمیگویم, not necessarily the truth of the embedded clause. Negative raising is strongest with gradable belief predicates such as فکر کردن and به نظر رسیدن, weaker or unavailable with factive knowledge and deliberate speech-act contrasts.
Polarity licensing across the clause boundary
Persian negative indefinites such as هیچکس، هیچچیز، هیچوقت normally require a negative licensor. In a negative-raising environment, matrix negation can license an item inside the complement.
فکر نمیکنم هیچکس از این تغییر راضی باشد.
fekr nemi-konam hich-kas az in taghyir râzi bâshad.
I don't think anyone is satisfied with this change. (neutral formal; matrix negation licenses هیچکس)
فکر میکنم هیچکس از این تغییر راضی نیست.
fekr mi-konam hich-kas az in taghyir râzi nist.
I think nobody is satisfied with this change. (neutral; embedded نیست licenses هیچکس)
In the second pattern, positive matrix فکر میکنم cannot license هیچکس by itself; embedded نیست does the work. The general concord system is explained on Negative Concord.
Pragmatic softening in disagreement
Matrix negation is a common face-saving strategy. It directs the overt “no” toward the speaker's own belief state rather than bluntly labeling the other person's proposition false.
فکر نمیکنم این نتیجه از دادههای موجود به دست بیاید.
fekr nemi-konam in natije az dâde-hâ-ye mowjud be dast biyâyad.
I don't think this conclusion follows from the available data. (academic discussion; softened disagreement)
این نتیجه از دادههای موجود به دست نمیآید.
in natije az dâde-hâ-ye mowjud be dast nemi-âyad.
This conclusion does not follow from the available data. (academic; direct negative assertion)
Softening does not make a claim empty. The first sentence still challenges the inference, but explicitly locates the judgment with the speaker.
A short exchange
— به نظرت تا فردا تمام میشود؟ — فکر نمیکنم؛ هنوز هیچکس بخش آخر را بررسی نکرده است.
— be nazar-at tâ fardâ tamâm mi-shavad? — fekr nemi-konam; hanuz hich-kas bakhsh-e âkhar râ barrasi na-karde ast.
— Do you think it will be finished by tomorrow? — I don't think so; nobody has reviewed the last section yet. (neutral workplace conversation)
Common Mistakes
1. Negating both clauses mechanically
❌ فکر نمیکنم که او نمیآید باشد.
Incorrect — the embedded indicative and subjunctive copula are stacked, and negation is duplicated without a coherent scope.
✅ فکر نمیکنم او امروز به جلسه بیاید.
fekr nemi-konam u emruz be jalase biyâyad.
I don't think he will come to the meeting today.
2. Using an indicative where a nonasserted complement needs the subjunctive
❌ فکر نمیکنم این راهحل عملی است باشد.
Incorrect — است and باشد cannot both close one predicate.
✅ فکر نمیکنم این پیشنهاد برای همه عملی باشد.
fekr nemi-konam in pishnehâd barâ-ye hame amali bâshad.
I don't think this proposal is practical for everyone.
3. Leaving هیچکس without a licensor
❌ فکر میکنم هیچکس از نتیجه راضی باشد.
Incorrect for ‘I think nobody is satisfied’ — positive فکر میکنم does not license هیچکس.
✅ فکر میکنم هیچکس از نتیجهی نهایی راضی نیست.
fekr mi-konam hich-kas az natije-ye nehâyi râzi nist.
I think nobody is satisfied with the final result.
4. Treating a softened claim as uncertainty about everything
❌ فکر نمیکنم شاید حتما درست باشد.
Incorrect — شاید and حتما assign incompatible strength to the same proposition.
✅ فکر نمیکنم این ادعا با شواهد فعلی سازگار باشد.
fekr nemi-konam in edde'â bâ shavâhed-e fe'li sâzgâr bâshad.
I don't think this claim is compatible with the current evidence.
Key Takeaways
- فکر نمیکنم بیاید often conveys a cautious belief that the person will not come, but can also mean simple absence of a positive belief.
- Matrix negation plus a subjunctive complement is softer than a direct embedded negative assertion.
- Literal matrix denial remains possible when contrast or continuation targets the thinking or saying act itself.
- Negative raising can license هیچکس inside the complement; a positive matrix needs embedded negation.
- Mood, polarity, and discourse context jointly reveal scope.
