Learn Turkish: Bu hakiki kilimi o koleksiyoncudan alıyorsun, değil mi? - You are buying this genuine rug from that collector, aren't you?

In Turkish, değil mi? is an invariable question tag used to seek confirmation, exactly like saying "right?" or "isn't that so?" in English. Unlike English, where the tag changes to match the subject and tense (aren't you, didn't he, won't they), the Turkish phrase değil mi? never changes.

How is the word koleksiyoncudan formed?

It starts with the loanword koleksiyon (collection). We add the occupational suffix -cu to mean "person who deals with collections," making koleksiyoncu (collector). Finally, the ablative suffix -dan (from) is added, resulting in "from the collector."

Why does kilim have an -i at the end (kilimi)?

Because the rug is the direct object being bought (alıyorsun). Since the rug is specifically pointed out by the word bu (this), it is a definite direct object. Definite direct objects require the accusative case suffix, which is -i here.

Does almak mean "to buy" or "to take" here?

The verb almak can mean "to take," "to buy," or "to get." You have to rely on the context to know which one is meant. Since the sentence talks about acquiring a genuine rug from a collector, "buying" is the most natural English translation, though "getting" would also work.
