Questions & Answers about راننده باید شهر را بشناسد و زیاد تمرین کند.
Why does the verb for 'know' look like beshnâsad instead of its normal present tense form?
Because it follows the modal verb bâyad (must). In Farsi, verbs following bâyad must be in the present subjunctive form. To build it, we take the present stem of shenâkhtan (to know or recognize), which is shenâs, add the subjunctive prefix be-, and attach the third-person ending -ad to match the driver.
Why is the verb for practice written as tamrin konad? Doesn't the subjunctive need a be- prefix?
That is a great observation! tamrin kardan (to practice) is a compound verb. When we put compound verbs into the subjunctive, only the helper verb (kardan) changes. Technically it becomes bekonad, but native speakers almost always drop the be- prefix on compound verbs. So, it simply becomes tamrin konad.
Does the word bâyad change if the subject is plural, like 'the drivers'?
No, bâyad is an impersonal modal verb. This means it is frozen in this form and stays exactly the same no matter who the subject is. The only verbs that change endings to match the subject are the main action verbs that come after it, like beshnâsad and tamrin konad.
What is the word râ doing after shahr (city)?
The word râ is a direct object marker that points to a specific thing. By saying , it shows that the driver needs to know 'the city' (a specific city), rather than just any city in general.
