Questions & Answers about تمام مواد باید توسط دولت بازیافت شوند.
Why do we use tavassot-e here, and could we use be vasile-ye instead?
tavassot-e means "by" or "via" and is used to introduce the "agent" (the doer of the action) in a passive sentence. You could use be vasile-ye instead, but tavassot-e is often preferred for people or organizations (like the government), while be vasile-ye (literally "by means of") is more commonly used for tools or inanimate objects.
Why is the verb shavand instead of mishavand, and where is the typical be- prefix?
The verb follows bâyad (must), which requires the subjunctive mood. The regular present subjunctive of shodan (to become/be) is beshavand. However, in compound verbs like bâzyâft shodan (to be recycled), the be- prefix is almost always dropped, leaving just shavand.
Is mavâd a plural word? It doesn't have a standard Farsi plural ending.
Yes, mavâd is the plural of mâdde (material/substance). It is a "broken plural" borrowed from Arabic, meaning its internal word structure changes entirely instead of taking a standard Persian plural suffix like -hâ.
Since mavâd (materials) is an inanimate object, shouldn't the verb be singular?
In Farsi, plural inanimate subjects often take a singular verb. However, using a plural verb like shavand is also perfectly correct and is frequently used in formal writing or to emphasize that every single material is involved. You could also correctly say bâzyâft shavad here.
