As mentioned in previous post, Subjunctive mood in Persian is used in two occasions. This mood is used when more than one verb is used, and in the case of uncertainty (i.e. after šāyad (maybe), agar (if), bāyad (must) and so on. The first usage of this mood was covered in the previous post, and the latter is explained in this post:
2. In the case of uncertainty
(i.e. after šāyad (maybe), agar (if), bāyad (must) and so on.
– May / Might
من شاید امروز به مدرسه بروم
/man šāyad emruz be madrese(h) beravam/
I might go to school today.
Note: There is no negative form for šāyad. To make the above sentence negative, we make the Subjunctive mood verb negative by replacing /be-/ with /na-/:
من شاید امروز به مدرسه نروم
/man šāyad emruz be madrese(h) naravam/
I might not go to school today.
– Should / Have to / Must / Ought to
حالت خوب نیست. تو باید به دکتر بروی.
/hālet xub nist. to bāyad be doktor beravi./
You are not ok. You have to go to the doctor. (=You have to see a doctor)
Note: Negative form for Bāyad is Nabāyad. To make the above sentence negative we change /bāyad/ to /nabāyad/ and do not touch the rest of sentence.
حالت خوب نیست. تو نباید به مدرسه بروی
/hālet xub nist. to nabāyad be madrese(h) beravi./
You are not OK. You must not go to school.
The subjunctive mood is not used for šāyad and Bāyad in past tense.
Past Imperfective form of the verb comes after šāyad and Bāyad in Past Tenses.
تو باید به او می گفتی
/to bāyad be u migofti/
You should have told her.
