Learn Turkish: Siyah araba nerede? - Where is the black car?

Just like in English, Turkish adjectives go before the noun they describe. So, "black car" is siyah araba. If you flipped the word order and said araba siyah, it would become a full statement meaning "the car is black."

The translation says "the black car." Where is the word for "the"?

Turkish doesn't have a separate word for "the" (a definite article). Because siyah araba is the main subject we are asking about, it is naturally understood as a specific car ("the black car") rather than just any car.

Where is the word for "is" in this sentence?

In simple present-tense sentences, Turkish usually doesn't need a verb at all! Siyah araba nerede? literally translates to "Black car where?". The "is" is simply understood from the context.

Why does the question word nerede end in -de?

The suffix -de is the location ending meaning "in," "on," or "at." The word nerede literally means "at what place?" Because you are asking about the current location of the car, you must use that -de ending.
