Questions & Answers about چرا خودت را گول میزنی؟
How do we build the word khodat (yourself) in this sentence?
It is made of the base word khod (self) plus the second-person singular possessive ending -at (your). If you wanted to say "myself", you would use -am to make khodam.
Why do we need the word râ right after khodat?
The word râ marks the specific direct object of the sentence. Reflexive pronouns like khodat point to a very specific person (you!), so they always need râ when they receive the action of the verb.
What kind of verb is gul mi-zani?
It is a compound verb made from gul (deceit or trick) and the common verb zadan (to hit). Together they mean "to deceive" or "to fool". Here it is conjugated for a single "you" with the present tense mi- prefix and the -i ending.
Is it wrong to include the word to (you) as the subject here?
No, you could say cherâ to khodat râ gul mi-zani? However, because the verb ending -i already tells us "you" are doing the action, dropping the pronoun to makes the sentence sound much more natural.
