çünkü
Because
Use çünkü to say "because." It connects a result to its reason: [Result] + çünkü + [Reason].
How It Works
The conjunction çünkü is the most common way to express causality in Turkish. While it originated from the Persian phrase čūn-ki, it is unique because it is one of the few words where the Persian particle ki has harmonized to follow vowel harmony (ü-ü).
1. Sentence Structure
In Turkish, native causal structures like -diği için usually put the reason first. However, çünkü follows the English-style order:
• Geç kaldım (Result) + çünkü + trafik vardı (Reason).
2. Grammatical Requirements
The clause following çünkü must be a "finite" clause. This means it needs a verb with a tense ending (like -iyor or -di) or a copula (like -(y)im or değil).
3. Punctuation and Style
Turkish punctuation guides often teach a comma or semicolon before çünkü when it joins two clauses (e.g., Gelmiyorum; çünkü çok ödevim var). In short sentences, writers may leave it out. While it is very common to start a spoken response or a literary sentence with çünkü when answering a neden (why) question, it is often avoided at the start of a sentence in highly formal academic prose to prevent sentence fragments.
Examples (4)
- Dışarı çıkmadık çünkü yağmur yağıyordu.
We didn't go out because it was raining.
Word by Word: Outside we-did-not-go because rain it-was-raining.
Here, the result (not going out) comes first, followed by the reason introduced by 'çünkü'.
- Sana yardım edemem çünkü çok işim var.
I can't help you because I have a lot of work.
Word by Word: To-you help I-cannot-do because much my-work there-is.
Note that 'işim var' is a complete statement on its own, which is required after 'çünkü'.
- Sınavdan düşük not aldı çünkü hiç çalışmamıştı.
He got a low grade on the exam because he hadn't studied at all.
Word by Word: From-exam low grade he-took because at-all he-had-not-studied.
This shows 'çünkü' used with the past perfect tense to explain a past result.
- Yemek yemedim çünkü aç değilim.
I didn't eat because I am not hungry.
Word by Word: Food I-did-not-eat because hungry I-am-not.
The reason clause uses 'değil' to show a state, which is perfectly valid after 'çünkü'.
Common Mistakes
Using a participle (-dik/-me) instead of a full verb after 'çünkü'.
Gelmedim çünkü hasta olduğum.Gelmedim çünkü hastaydım.'Çünkü' must be followed by a complete sentence with a tensed verb or personal ending, not a noun-like verb form.
Confusing 'çünkü' (because) with 'bu yüzden' (therefore).
Hava soğuk çünkü ceketimi giydim.Hava soğuk, bu yüzden ceketimi giydim.'Çünkü' introduces the cause. If you want to introduce the result, use 'bu yüzden'.
Starting a sentence with 'çünkü' to mean 'Because [Reason], [Result]'.
Çünkü yağmur yağdı, evde kaldık.Yağmur yağdığı için evde kaldık.In Turkish, you cannot start a sentence with 'çünkü' to introduce a reason before the result. If you want to put the reason first, you must use the -diği için structure.
How It Connects
Learn This First
To use 'çünkü' (because) effectively, you need to be able to construct two independent clauses—either verbal or non-verbal—and understand the relationship between a reason and its result, typically answering the question 'why'.
