Questions & Answers about این سنگ در اثر فرسایش و رسوب تشکیل میشود.
Could I use nâshi az instead of dar asar-e in this sentence?
No, they are not interchangeable here. The phrase dar asar-e is used adverbially to explain how the verb happens (how the rock is formed). On the other hand, nâshi az acts as an adjective phrase that modifies a noun, so you would use it for a phrase like "the rock resulting from erosion" (sang-e nâshi az farsâyesh) rather than modifying the action of forming itself.
How does the ezâfe work with dar asar-e and the two nouns following it?
The phrase is literally "in the effect of", so the word asar (effect) takes an ezâfe to link it to the cause. Here, the cause is a compound phrase joined by va (and): farsâyesh va rosub. The ezâfe goes on asar-e, pointing to the entire concept of "erosion and sediment", so you do not put another ezâfe after farsâyesh.
The word for erosion is farsâyesh. How is this noun formed?
It is formed by taking the present stem of the verb farsudan (to wear out or decay), which is farsây-, and adding the noun-forming suffix -esh. This suffix is very commonly used in Farsi to turn the action of a verb into a process-based noun.
Why use the compound verb tashkil mishavad instead of a single word for "formed"?
Farsi relies heavily on compound verbs for concepts that have single words in English. For "to form", Farsi uses tashkil dâdan (active: to form or constitute something) or tashkil shodan (passive or intransitive: to be formed). Since the rock is the subject undergoing the natural process, we use the shodan form here, conjugated in the present tense.
