Questions & Answers about بر اساس مقررات صنف، الزامی است که شما سیستم فاضلاب داشته باشید.
Why is 'dâshte bâshid' used here for 'have' instead of a normal subjunctive form with a 'be-' prefix?
The verb dâshtan (to have) does not form its present subjunctive normally. Instead of adding a be- prefix, it uses its past participle dâshte combined with the subjunctive forms of the verb 'to be' (here, bâshid). Even though this combination looks exactly like the present perfect tense, in this sentence it acts as the present subjunctive because it is triggered by elzâmi ast ke (it is mandatory that).
What does the phrase 'bar asâs-e' mean at the start of the sentence?
It means 'based on' or 'according to'. It is a very common and useful B2-level phrase for citing rules, laws, or opinions. It always takes an Ezafe to connect it to the noun that follows, which in this case is mogharrarât (regulations).
Why use 'elzâmi ast' instead of just saying 'bâyad' (must)?
Elzâmi ast is a formal, official way to say 'it is mandatory' or 'it is compulsory'. Since this sentence is discussing official guild regulations (mogharrarât-e senf), this phrasing fits the legal tone much better than the everyday bâyad. Just like bâyad, it requires the following verb to be in the subjunctive mood.
How is the compound word 'fâzelâb' (wastewater) formed?
It is made by combining the Arabic-derived word fâzel (meaning excess, surplus, or waste) and the Persian word âb (water). Here it connects to the word for system with an Ezafe, pronounced as sistem-e fâzelâb.
