Questions & Answers about ضروری است که مبتدیها با یک مربی تمرین کنند.
Why is the verb tamrin konand in the subjunctive here?
The sentence starts with the impersonal expression zaruri ast ke (it is necessary that). Expressions of necessity, obligation, or desire trigger the present subjunctive in the following subordinate clause. That is why we see the subjunctive tamrin konand rather than the indicative tamrin mikonand.
Shouldn't the subjunctive verb have a be- prefix, like tamrin bokonand?
While tamrin bokonand is technically correct, native speakers almost always drop the be- prefix in the subjunctive for compound verbs made with kardan. So tamrin konand is the most natural and expected form here.
Can I use bayad (must) instead of zaruri ast ke?
Yes, you could say mobtadi-ha bayad ba yek morabbi tamrin konand. However, zaruri ast ke is slightly more formal and directly translates to 'it is necessary that,' which places more emphasis on the objective necessity of the action rather than just a general obligation.
Could the plural suffix -an be used for mobtadi instead of -ha?
Yes, since mobtadi (beginner) refers to a human, you can use the animate plural suffix -an, making it mobtadiyan (notice the 'y' glide consonant added for smooth pronunciation). Both mobtadi-ha and mobtadiyan are perfectly correct, though -ha is much more common in everyday Farsi.
