Questions & Answers about بعضی از یختاقها در حال فرو ریختن هستند، حال آنکه بقیه پایدار هستند.
How formal is حال آنکه in this sentence, and what would I use in everyday speech?
حال آنکه (whereas / while in fact) is quite formal and is mostly used in writing, literature, or news broadcasts. In everyday conversation, you would typically just use در حالی که (while) or even a simple ولی (but) to show this contrast.
Why is the infinitive فرو ریختن used here instead of a conjugated verb?
The phrase در حال (in the process of) requires an infinitive to act as a noun (similar to an English gerund). So در حال فرو ریختن literally translates to "in the state of collapsing." The time and subject of the action are shown by the "to be" verb at the end of the clause (هستند).
یختاقها is a very specific word. How is it constructed?
It is a compound noun made of یخ (ice) and تاق (arch, vault, or shelf), followed by the plural suffix ها.
Inanimate plural subjects normally take singular verbs in Farsi. Why does بعضی از یختاقها take the plural verb هستند?
While inanimate objects usually take singular verbs, using quantifiers like بعضی از (some of) or برخی از (a few of) often triggers a plural verb, especially in formal writing. This is because the phrasing emphasizes a specific, countable subset of those items.
