Questions & Answers about کارشناسان گزارشهایی مبنی بر اینکه وقوع گردباد قطعی است منتشر کردهاند.
Why do we use mabni bar in ke here instead of just ke?
While ke simply means "that," مبنی بر اینکه (mabni bar in ke) is a more formal reporting phrase meaning "based on the fact that" or "indicating that." It is used to cleanly connect a noun like گزارشهایی (reports) to the specific claim being made inside those reports.
Could I use hâki az in ke in this sentence instead?
Yes, they are almost perfectly interchangeable here. حاکی از اینکه (hâki az in ke) translates closer to "telling of" or "indicative of," while مبنی بر اینکه (mabni bar in ke) literally means "based upon." Both are excellent B2-level choices for introducing the contents of a report, evidence, or statement.
Why is there a یی (-yi) at the end of گزارشهایی?
This is the indefinite ی (-i), meaning "some reports" or "a few reports." When followed by a descriptive or reporting clause like مبنی بر اینکه, it acts as a bridge pointing forward to the specific description, similar to saying "certain reports indicating that...". Also, because these are indefinite reports, the specific direct object marker را (râ) is omitted.
Why is the compound verb منتشر کردهاند (have published) placed so far away from its object گزارشهایی?
In Farsi, the verb belongs at the very end of the sentence. The entire phrase گزارشهایی مبنی بر اینکه وقوع گردباد قطعی است acts as one long direct object. So, the main structure is simply: Experts (Subject) + [Reports indicating that...] (Object) + have published (Verb).
The word وقوع (voqu') seems formal. Is it related to واقعی (vâqe'i)?
Yes! Both come from the same Arabic root relating to things happening or existing. وقوع is a formal noun meaning "occurrence" or "happening," while واقعی means "real" or "actual." You will often see وقوع used in the news regarding natural disasters, crimes, or major events.
