Persian Relative Clauses: Using 'ke' to describe people and things (که)
که and an '-i' suffix to create natural, complex Persian sentences.
Grammar Rule in 30 Seconds
Use the particle 'ke' (که) to connect a noun to a descriptive phrase, acting like 'who', 'which', or 'that'.
- Place 'ke' immediately after the noun you are describing: 'The book that I read' -> 'Ketabi ke...'
- The verb in the relative clause usually goes to the end of the clause.
- If the noun is the object of the clause, use the 'ra' (را) marker after the noun or at the end of the clause.
Overview
Mastering Persian requires moving beyond simple declarative sentences to express nuanced ideas and complex relationships between entities. One of the most powerful tools for achieving this is the relative clause, introduced by the ubiquitous particle که (ke). This particle serves as the primary relative pronoun in Persian, connecting a main clause to a dependent clause that provides additional information about a noun (the antecedent) in the main clause.
Unlike English, which employs a variety of relative pronouns such as “who,” “which,” “that,” “whom,” and “whose,” Persian elegantly simplifies this system. که is invariant; it does not change its form based on whether the antecedent is human or non-human, singular or plural, or masculine or feminine. This singular form streamlines sentence construction, making که a foundational element for B1 learners aiming for greater fluency and descriptive capability.
که allows you to expand upon nouns, transforming basic statements like من یک مرد را دیدم. (man yek mard râ didam.) – “I saw a man.” – into more detailed expressions such as من مردی را دیدم که در پارک قدم میزد. (man mardi râ didam ke dar pârk qadam mi-zad.) – “I saw a man who was walking in the park.” Understanding its structure and application is crucial for building sophisticated sentences and conveying precise information.
How This Grammar Works
که functions as a relative conjunction (حرف ربط موصولی - harf-e rabt-e movasuli), initiating a dependent relative clause (جمله موصولی - jomle-ye movasuli) that modifies an antecedent noun (اسم پیشین - esm-e pishin). This clause acts adjectivally, providing essential or non-essential descriptive information about the noun it follows. The clause introduced by که cannot stand alone as a complete sentence; its meaning is dependent on the antecedent it modifies.ضمیر بازگشتی - zamir-e bâzgashti). This pronoun appears within the relative clause and refers back to the antecedent, acting as a placeholder or reminder. While seemingly redundant from an English perspective, its presence is often grammatically obligatory or stylistically preferred in Persian, especially when the antecedent functions as the object of a verb or preposition within the relative clause.این کتابی است که آن را دیروز خریدم. (in ketâbi ast ke ân râ diruz kharidam.) – “This is the book that I bought (it) yesterday.” Here, آن را (ân râ), meaning “it” (with the direct object marker را - râ), is the resumptive pronoun. It clarifies that کتاب (ketâb) – “book” – is the direct object of the verb خریدم (kharidam) – “I bought.” Without آن را, the sentence این کتابی است که دیروز خریدم. would be grammatically ambiguous or incorrect, potentially implying that the book itself did the buying.که coupled with the strategic use of resumptive pronouns creates a flexible yet precise mechanism for constructing complex sentences in Persian.Word Order Rules
که, must immediately follow the noun it describes. There is no separation, unlike in some English constructions where relative clauses can be offset by commas. This strict adjacency ensures unambiguous modification.-ی (-i), before که. This -ی serves a crucial function: it particularizes the noun, indicating that a specific, yet previously undefined, instance of that noun is about to be described or defined by the subsequent relative clause. Think of it as a flag signaling that more information about this specific noun is coming.که + [Relative Clause (Subject + Object + Verb)].مردی که آمد، دوستم بود.(mardi ke âmad, dustam bud.) – “The man who came was my friend.”- Here,
مرد(mard) – “man” – takes-یto becomeمردی(mardi). The clauseکه آمد(ke âmad) – “who came” – directly follows and describesمردی.
خانهای که در آن زندگی میکنم، قدیمی است.(khâneyi ke dar ân zendegi mi-konam, qadimi ast.) – “The house in which I live is old.”خانه(khâne) – “house” – becomesخانهای(khâneyi) due to the final vowel requiring an epentheticـی. The clauseکه در آن زندگی میکنم(ke dar ân zendegi mi-konam) follows immediately.
این (in) – “this” or آن (ân) – “that,” or a possessed noun), the -ی suffix is generally omitted. This is because the noun is already sufficiently particularized. For example, علی که دوست من است، دیروز به تهران رفت. (ali ke dust-e man ast, diruz be Tehrân raft.) – “Ali, who is my friend, went to Tehran yesterday.” Here, علی (ali) is a proper noun and does not require -ی.که has established the relative clause boundary.Formation Pattern
که involves a precise sequence of steps, building a descriptive layer onto your sentences. This pattern is highly regular, offering a reliable framework for expansion:
دانشجو (dâneshju) – “student”
-ی: For most common nouns that are not inherently definite (like proper nouns or those with demonstratives), you must attach the suffix -ی (-i) to the end of the noun. This suffix signals that the noun is about to be qualified by a relative clause.
کتاب (ketâb) → کتابی (ketâbi) – “a book”
ه (he): خانه (khâne) → خانهای (khâneyi) – “a house”
ا, و, ی): جو (jow) – “barley” → جویی (jowi). This is less common.
-ی if the noun is already specific (e.g., proper nouns like مریم (Maryam), nouns with demonstratives like آن پسر (ân pesar) – “that boy,” or possessed nouns like ماشین من (mâshin-e man) – “my car”).
دانشجویی (dâneshju-yi) – “a student”
که: Place the relative conjunction که (ke) immediately after the (modified) antecedent noun. This particle marks the beginning of your relative clause.
دانشجویی که (dâneshju-yi ke) – “a student who...”
مردی که آمد، دوستم بود. (mardi ke âmad, dustam bud.) – “The man who came was my friend.” |
او را (u râ) for animate, آن را (ân râ) for inanimate | کتابی که آن را خواندم، گم شد. (ketâbi ke ân râ khândam, gom shod.) – “The book that I read it, got lost.” |
او (u) for animate, Preposition + آن (ân) for inanimate | استادی که با او صحبت کردم، خیلی مهربان بود. (ostâdi ke bâ u sohbat kardam, kheyli mehrabân bud.) – “The professor with whom I spoke, was very kind.” خانهای که در آن زندگی میکنم، بزرگ است. (khâneyi ke dar ân zendegi mi-konam, bozorg ast.) – “The house in which I live (in it), is large.” |
دانشجویی که فارسی خیلی خوب صحبت میکند (dâneshju-yi ke fârsi kheyli khub sohbat mi-konad) – “A student who speaks Persian very well.”
-ی suffix and the careful inclusion of resumptive pronouns are hallmarks of grammatically correct and natural-sounding Persian.
When To Use It
که are indispensable for building complex and informative sentences. They serve several key functions, moving your Persian beyond basic statements to a more expressive and nuanced level:- To Provide Essential Identifying Information (Restrictive Clauses):
پزشکی که دیروز دیدم، دکتر خوبی بود.(pezeshki ke diruz didam, doktor-e khubi bud.) – “The doctor that I saw yesterday was a good doctor.” (You're specifying which doctor.)لباسی که برای تولدم خریدی، خیلی قشنگ است.(lebâsi ke barâ-ye tavallodam kharidi, kheyli qashang ast.) – “The dress that you bought for my birthday is very beautiful.” (Specifies which dress.)
- To Add Non-Essential, Supplementary Information (Non-Restrictive Clauses):
مادرم، که پزشک است، به بیماران زیادی کمک میکند.(mâdaram, ke pezeshk ast, be bimârân-e ziyâdi komak mi-konad.) – “My mother, who is a doctor, helps many patients.” (Your mother is already identified; being a doctor is extra info.)تهران، که پایتخت ایران است، شهری بزرگ و پرجمعیت است.(Tehrân, ke pây-takht-e Irân ast, shahri bozorg va por-jam'iyat ast.) – “Tehran, which is the capital of Iran, is a big and populous city.”
- To Combine Sentences and Avoid Repetition:
- Instead of:
من یک فیلم خوب دیدم. فیلم دربارهٔ زندگی یک هنرمند بود.(man yek film-e khub didam. film dar-bâre-ye zendegi-ye yek honarmand bud.) – “I saw a good movie. The movie was about an artist’s life.” - Use:
فیلم خوبی که دیدم، دربارهٔ زندگی یک هنرمند بود.(film-e khubi ke didam, dar-bâre-ye zendegi-ye yek honarmand bud.) – “The good movie that I saw was about an artist’s life.”
- For Rhetorical Emphasis or to Convey Emotion:
غذایی که سفارش دادم هنوز نرسیده است!(ghazâ-yi ke sefâresh dâdam hanuz naraside ast!) – “The food that I ordered hasn’t arrived yet!” (The clause highlights the specific problem.)
که allows you to craft more sophisticated and natural-sounding Persian, reflecting the way native speakers weave details into their narratives. It's a hallmark of intermediate-level fluency.Common Mistakes
- Omitting the Indefinite Suffix
-ی(-i): This is arguably the most frequent and jarring mistake for B1 learners. When a common noun is being introduced to be defined by a relative clause, the-یsuffix is almost always required. Its absence often makes the sentence sound incomplete or ungrammatical. - Incorrect:
مرد که آمد، دوستم بود.(mard ke âmad, dustam bud.) – Sounds like “Man who came, was my friend.” - Correct:
مردی که آمد، دوستم بود.(mardi ke âmad, dustam bud.) – “The man who came was my friend.” - Why it's wrong: The
-یfunctions as an indefinite marker that also serves as a syntactic bridge. Without it, the grammatical connection between the noun andکهis broken, similar to saying
