Learn Farsi: باد وزان و طوفان غران روستا را خراب کردند. - The blowing wind and the roaring storm destroyed the village.

They are present participles created by adding the suffix -ân to a verb's present stem. vazân comes from the stem vaz (from vazidan, to blow), and qorrân uses the stem qorr (from qorridan, to roar). In this sentence, they act as adjectives describing the continuous state of the wind and storm.

Is there an ezafe linking the nouns to these new adjectives?

Yes! Even though it is not written, you must pronounce the ezafe to link the nouns to their adjectives: bâd-e vazân (blowing wind) and tufân-e qorrân (roaring storm). The ezafe is invisible here because both bâd and tufân end in consonants.

bâd and tufân are inanimate objects. Why does the verb xarâb kardand (destroyed) take a plural ending?

While inanimate plural subjects often take a singular verb in Farsi, there are two exceptions at play here. First, there is a compound subject joined by va (and). Second, when inanimate forces of nature act violently or are personified (like a roaring storm), native speakers frequently choose a plural verb to emphasize their active power.

Why do we need the word râ after rustâ (village)?

râ is the specific direct object marker. The wind and storm destroyed a specific village, so must be immediately followed by to show it is the direct receiver of the action.
