Learn Farsi: مدیر خودش دادوستد در شرکت را کنترل می‌کند. - The manager himself controls the trade in the company.

Dâdosetad is a perfect example of a coordinate compound noun made of two bare past stems. It combines dâd (the past stem of dâdan, to give) and setad (the past stem of the older verb setadan, to take), linked by the conjunction o (and). Literally meaning 'gave and took', it acts as a single abstract noun for 'trade' or 'commerce'.

Why is the direct object marker râ placed after dar sherkat instead of right after dâdosetad?

In Farsi, when a direct object is modified by a prepositional phrase that acts as an essential part of the noun phrase (here, 'the trade in the company'), the whole phrase is often treated as a single block. Therefore, the direct object marker râ is pushed to the very end of that block, attaching to sherkat rather than dâdosetad.

What role does khodesh play in this sentence?

Here, khodesh is used for emphasis, translating to 'himself' or 'herself'. It emphasizes that the manager personally does the controlling, rather than delegating it to someone else. It immediately follows the subject modir (manager) to reinforce it.

I thought kontrol kardan meant 'to check'. Does it mean 'to control' here?

Yes, kontrol kardan can mean both 'to check/inspect' (like checking a ticket) and 'to control/manage' (like running a process or overseeing trade). The context of overseeing trade operations makes 'control' or 'manage' the natural translation here.
