Learn Farsi: پرنده در ازای غذا، هم فرمانبردار و هم وفادار است. - In return for food, the bird is both obedient and loyal.

It connects using an ezâfe. dar ezâ-ye means "in return for" or "in exchange for", and like many compound prepositions in Farsi, it requires an ezâfe to link it to the following noun. Because ezâ ends in a vowel, the ezâfe takes the form of a "ye" sound, giving us dar ezâ-ye ghazâ (in return for food).

What is the literal breakdown of the word farmânbardâr (obedient)?

It is a compound word made of farmân (command or order) and bardâr (the present stem of the verb bardâshtan, to take or bear). So, a bird that is farmânbardâr literally "takes commands".

Is the word vafâdâr (loyal) built using a similar compound structure?

Yes, it combines the noun vafâ (loyalty or faithfulness) with dâr (the present root of dâshtan, to have or hold). An animal or person who is vafâdâr literally "holds loyalty".

Why are there two ham words in this sentence?

The structure ham ... va ham ... is the Farsi equivalent of "both ... and ...". Here it links the two adjectives: ham farmânbardâr va ham vafâdâr (both obedient and loyal). Keep in mind that Farsi still requires the word va (and) in the middle, which is often pronounced as just "o" in everyday speech.
