Learn Turkish: Belgenin elden ele dolaşacağını umuyoruz. - We hope that the document will circulate from hand to hand.

This is a common pattern used to show gradual progression or physical transfer. You take a noun, add the ablative suffix (-dAn, meaning "from"), repeat the same noun, and add the dative suffix (-(y)A, meaning "to"). Here, el (hand) becomes elden ele. You can use this with many nouns, such as günden güne (from day to day) or kulaktan kulağa (from ear to ear, often used for rumors).

Why is the document marked with the genitive case as belgenin?

This sentence uses a noun clause to express "that the document will circulate." In Turkish, this is framed as "the document's future-circulating." Therefore, the subject of this embedded clause (belge) takes the genitive suffix (-nin), securely linking it to the possessive suffix on the verb that follows.

Can you break down the suffixes on the word dolaşacağını?

Certainly! It starts with the verb root dolaş (wander/circulate). We add the future nominalizer -acak, which softens to -acağ due to the following vowel. Next is the 3rd person singular possessive -ı, which acts as the "its" linking back to belgenin. Finally, we add the buffer -n- and the accusative case -ı. The accusative case is strictly required here because this entire embedded clause acts as the direct object of the main verb umuyoruz (we hope).
