Grammar Rule in 30 Seconds
Use 'که' (ke) to connect a main clause to a subordinate clause, functioning exactly like the English 'that'.
- Use 'که' after verbs of thinking, saying, or feeling: من فکر میکنم که او میآید (I think that he is coming).
- It acts as a bridge between two ideas: میدانم که تو خستهای (I know that you are tired).
- In informal speech, 'که' is often dropped or attached to the previous word: میدونم خستهای (I know [that] you're tired).
Overview
که (ke) is crucial for transitioning from simple sentence structures to more complex, nuanced expressions. This particle primarily functions as a subordinating conjunction, akin to the English that, introducing a complement clause. These complement clauses act as the object or complement of a preceding verb, often one of cognition, communication, or emotion.که allows you to report thoughts, relay speech, or express feelings about a complete idea or event.من میدانم (man midânam - I know). What do you know? You can follow this with a direct object, like حقیقت (haghighat - the truth).او میآید (u miâyad - he is coming), که forms the bridge: من میدانم که او میآید. (I know that he is coming). Here, the entire clause که او میآید functions as the object of میدانم. This structure is fundamental for expressing intricate ideas and moving beyond basic communication in Persian.How This Grammar Works
که in this context introduces a declarative complement clause. This clause functions as a grammatical argument of the main verb, typically as a direct object. The main verb, known as a clause-embedding verb, governs the relationship between the main statement and the embedded clause.که.که introduces a complement clause, the clause it introduces acts as the direct object of the main verb. For example, in او گفت که باران میآید. (u goft ke bâran miâyad - He said that it is raining.), باران میآید (it is raining) is the specific content of what he said. This structure is pervasive in Persian, appearing across all communicative registers, from casual conversation to formal written discourse.که clause is determined by the nature of the main verb. Generally, verbs of reporting, cognition, and perception (e.g., گفتن - to say, فکر کردن - to think, دانستن - to know, دیدن - to see) are followed by a که clause with an indicative verb. This signifies that the content of the که clause is presented as a fact or a perceived reality.ما شنیدیم که او برنده شد. (mâ shenidim ke u barande shod - We heard that he won.) uses the indicative شد (shod - he became).خواستن - to want, امیدوار بودن - to hope, پیشنهاد کردن - to suggest, ترسیدن - to fear, لازم بودن - to be necessary) typically require the verb in the که clause to be in the subjunctive mood. The subjunctive reflects uncertainty, possibility, non-factuality, or a desired outcome. For instance, امیدوارم که او بیاید. (omidvâram ke u biâyad - I hope that he comes.) uses the subjunctive بیاید (biâyad - he comes/may come), reflecting the hope rather than a certainty of his arrival.
Formation Pattern
که as a complementizer follows a consistent structure: Main Clause + که + Complement Clause. The main clause establishes the speaker's action, thought, or emotion, while the complement clause provides the content. The specific conjugation of the verb in the complement clause depends on the main verb's semantic category.
من میدانم (I know) | او میخواهد (He wants) |
که | که | که |
شما مشغول هستید (you are busy) | شما مشغول باشید (you be busy) |
من میدانم که شما مشغول هستید. | او میخواهد که شما مشغول باشید. |

When To Use It
که is a workhorse in Persian, indispensable for constructing grammatically complete and logically flowing sentences. You will encounter and use it extensively in a variety of contexts:- Reporting Speech and Thoughts: This is perhaps the most frequent application. When you relay what someone else has said, thought, or communicated,
کهintroduces the direct content of their utterance or mental state. علی گفت که فردا نمیتواند بیاید.(ali goft ke fardâ nemitavânad biâyad - Ali said that he cannot come tomorrow.)من فکر میکنم که ایدهی خوبی است.(man fekr mikonam ke ideye khubi ast - I think that it is a good idea.)- Notice how the verb in the
کهclause maintains its own tense and aspect, independent of the main verb's tense, unless a subjunctive is required.
- Expressing Beliefs, Opinions, and Knowledge: When you state a personal belief, an opinion, or a piece of information you know to be true,
کهframes this knowledge as the complement of your cognitive verb. ما معتقدیم که عدالت مهمترین اصل است.(mâ mo'taghedim ke edâlat mohem-tarin asl ast - We believe that justice is the most important principle.)او میدانست که امسال برف زیادی میبارد.(u midânest ke emsâl barf-e ziyâdi mibârad - He knew that it would snow a lot this year.)
- Conveying Hopes, Wishes, Fears, and Desires: This category almost always mandates the subjunctive mood in the
کهclause, as it deals with non-factual or aspirational situations. امیدوارم که سفرتان امن باشد.(omidvâram ke safaretân amn bâshad - I hope that your trip is safe.)من میخواهم که آنها به توافق برسند.(man mikhâham ke ânhâ be tavâfoq beresand - I want them to reach an agreement.)مادرم نگران است که سرما بخورم.(mâdaram negarân ast ke sarmâ bokhoram - My mother is worried that I might catch a cold.)
- After Adjectives or Nouns Expressing Emotion or Certainty: Certain adjectival constructions or abstract nouns can also take a
کهclause to specify the cause or content of the emotion/certainty. من خوشحالم که شما به من اعتماد دارید.(man khoshhâlam ke shomâ be man e'temâd dârid - I am happy that you trust me.)مطمئن هستم که او موفق خواهد شد.(motma'en hastam ke u movaffaq khâhad shod - I am certain that he will succeed.)
- When Expressing Necessity or Obligation: Impersonal expressions of necessity often use
کهwith a subjunctive clause. لازم است که همه حاضر باشند.(lâzem ast ke hame hâzer bâshand - It is necessary that everyone be present.)باید که این کار را انجام دهیم.(bâyad ke in kâr râ anjâm dahim - We must do this work.)
Common Mistakes
که as a complementizer. Recognizing these pitfalls is the first step towards avoiding them.که in Formal or Ambiguous Contexts:که can be omitted in very casual spoken Persian, particularly after common verbs like فکر کردن (to think) or گفتن (to say), this practice can lead to ambiguity or sound ungrammatical in more formal or written settings. For intermediate learners, it is always safer and clearer to include که.- Incorrect (or overly casual):
او گفت میاد.(u goft miyâd - He said he's coming.) - Correct and Clear:
او گفت که میآید.(u goft ke miâyad - He said that he is coming.) - Why it's a mistake: Without
که, the relationship between the two clauses is less explicit. While context often clarifies it in speech, in writing, or when the clauses are more complex, its absence can cause confusion.
که Clause:- Error (Subjunctive required):
من میخواهم که او میرود.(man mikhâham ke u miravad - I want that he goes.) (Incorrect indicative) - Correction:
من میخواهم که او برود.(man mikhâham ke u beravad - I want him to go.) (Correct subjunctive) - Why it's a mistake: The verb
خواستن(to want) expresses a desire, not a fact. Therefore, the outcome (رفتن- to go) is non-factual or desired, necessitating the subjunctive mood. Using the indicative implies you *know* he is going, rather than *wanting* him to go.
- Error (Indicative required):
او گفت که من بروم.(u goft ke man beravam - He said that I go.) (Incorrect subjunctive for reported speech) - Correction:
او گفت که من میروم.(u goft ke man miravam - He said that I am going.) (Correct indicative) - Why it's a mistake:
گفتن(to say) reports a statement. If the original statement wasمن میروم(I am going), reporting it requires the indicative, not the subjunctive. The subjunctive here would imply a command or suggestion, changing the meaning toHe told me to go.
که with Relative Pronoun که:که for two distinct grammatical functions, leading to significant confusion. While both connect clauses, they do so in fundamentally different ways.- Conjunction
که(Complementizer): Connects a main verb (likeگفتن,فکر کردن) to an entire clause that functions as the *object* of that verb. - Structure: Main Clause (Verb) +
که+ Complement Clause - Example:
من میدانم که او در خانه است.(man midânam ke u dar khâne ast - I know *that* he is at home.) - Test: Can you replace the
کهclause with a simple noun? (من میدانم حقیقت را.- I know the truth.) If yes, it's a complementizer.
- Relative Pronoun
که: Connects a noun to a clause that modifies or describes that noun. It functions like

常见问题 (8)
In speech, yes, often. In formal writing, no, you should keep it.
No, the verb tense depends on the meaning of the subordinate clause, not the connector.
It can function as a relative pronoun like 'who' or 'which', but it's not a direct translation of the interrogative 'who' (which is 'چه کسی').
'اینکه' is 'این' (this) + 'که' (that). It is used to refer to a whole clause as a subject.
Only in specific exclamatory or poetic contexts, not in standard prose.
It is 'که'. The pronunciation is short.
That would be redundant and incorrect. Use one or the other.
Some dialects might use different particles, but 'که' is universal in standard Persian.
