Questions & Answers about به محض تزریق دارو، درد کاهش مییابد.
How does the phrase be mahz-e connect to the action in this sentence?
It connects using the Ezafe. The structure for this formal phrasing is be mahz-e + [Abstract Noun or Infinitive]. Here, we have the Ezafe chain be mahz-e tazrigh-e dāru (upon the injection of the medicine).
I am used to saying be mahz-e inke with a conjugated verb. Why is there no inke or conjugated verb here?
Adding inke turns it into a conjunction that requires a full clause with a subjunctive verb (e.g., be mahz-e inke dāru tazrigh shavad - as soon as the medicine is injected). Dropping inke and using a noun like tazrigh (injection) creates a formal, compact prepositional phrase that is very common in written Farsi.
Why use kāhesh mi-yābad instead of the more common kam mi-shavad for "decreases"?
Kāhesh yāftan (literally "to find decrease") is an elevated, formal compound verb. It perfectly matches the formal tone set by the be mahz-e + noun structure, making this sentence sound like a medical leaflet or news report rather than an everyday chat.
The lesson mentions using abstract nouns or "long infinitives" after be mahz-e. Is tazrigh a long infinitive?
No, tazrigh (injection) is an abstract noun. A Persian infinitive always ends in -dan or -tan. If the sentence used a Persian infinitive instead, it would be be mahz-e tazrigh kardan-e dāru (upon injecting the medicine). Both forms are grammatically correct for this structure.
