Learn Farsi: ما اجازه نمی‌دهیم که زندانی‌ها در زندان سلاح خطرناک داشته باشند. - We do not allow the prisoners to have dangerous weapons in prison.

In English, we say "allow someone TO HAVE". In Farsi, you must use two full phrases joined by ke (that). The structure literally translates to: "We do not give permission that prisoners may have...". After verbs of permission like ejâze dâdan (to allow), the second verb must always be in the present subjunctive form.

Why does the subjunctive verb "dâshte bâshand" look different from normal subjunctive verbs? Where is the "be-" prefix?

The verb dâshtan (to have) is an exception to the normal subjunctive rules. Instead of adding a be- prefix to a present stem, it forms its subjunctive by taking the past participle dâshte and adding the subjunctive forms of "to be" (bâsham, bâshi, etc.). Since "prisoners" is a plural "they" subject, we use bâshand.

I see "zendâni-hâ" and "zendân" in this sentence. How do these words relate?

Zendân means "prison". By adding the suffix -i, you create a noun for a person associated with that place: zendâni (prisoner). Finally, the standard plural suffix -hâ is added to make zendâni-hâ (prisoners).

How do we link "weapon" (selâh) and "dangerous" (khatarnâk)?

In Farsi, adjectives come after the noun they describe, and they are linked by an "eh" sound called the Ezafe. You won't see it written in the standard Farsi alphabet, but you must pronounce "dangerous weapon" as selâh-e khatarnâk.
