Questions & Answers about ما قصد داریم که مسیر کشتی را تغییر دهیم.
Why doesn't the second verb تغییر دهیم have the usual بـ (be-) prefix for the subjunctive?
It is indeed in the subjunctive, triggered by قصد داریم (we intend). However, تغییر دادن is a compound verb. With compound verbs, the بـ (be-) prefix is very often dropped, because the non-verbal part of the verb (تغییر) is already sitting right next to the helper verb (دهیم).
Can I leave out the word که (ke) after قصد داریم?
Yes! While که (that) is common in written Farsi to connect the intention to the action, native speakers frequently drop it in everyday conversation. Saying ما قصد داریم مسیر کشتی را تغییر دهیم without it is perfectly natural.
Why does the object marker را (râ) come after کشتی (ship) instead of مسیر (route)?
You are changing the route, but مسیر کشتی (the ship's route) acts as one complete noun phrase linked by the invisible 'ezafe' vowel. The specific object marker را must always be placed at the very end of the entire noun phrase it marks.
How does the verb تغییر دهیم work here? I thought the root was related to giving.
You are right! 'To change' is expressed with the compound verb تغییر دادن (taghyir dâdan), which literally translates as 'to give change'. Here, the helper verb is conjugated in the present subjunctive for 'we' (دهیم), meaning 'that we change'.
