### Another Word for "Why"

You just learned **neden** (why). Turkish has a second why-word you will hear just as often: **niçin** (why — for what reason). The two are fully interchangeable — every **neden** question works with **niçin**, and the answer still begins with **çünkü**.

In relaxed everyday speech you will also hear *niye* — a third, casual way to ask the very same question.

### Question and Reason, Side by Side

Whichever why-word you pick, the rhythm is the same: ask with **niçin**, answer with **çünkü**.
