Questions & Answers about چرخش این سیاره را دیدی؟
How is the word for "rotation" (چرخش) formed in this sentence?
It is an action noun created from the verb charkhidan (to turn or rotate). You take the present stem of the verb, which is charkh, and add the suffix -esh (ـش). This is a standard pattern for turning an action into a noun in Farsi.
Where does the hidden "ezafe" vowel go in this sentence?
It attaches to the end of "rotation" to link it to the rest of the phrase. You pronounce it as charkhesh-e in sayyaareh (the rotation of this planet). The ezafe always goes on the head noun being described or possessed.
Why is the direct object marker "raa" (را) placed after "planet" instead of right after "rotation"?
The word raa (را) must follow the entire direct object phrase, not just the first word. Because the specific object you saw is the whole phrase "the rotation of this planet" (charkhesh-e in sayyaareh), the marker raa goes at the very end of it.
The word for planet (سیاره) ends in the letter "h" (ه). How is it pronounced before the "raa" (را)?
In words like sayyaareh (سیاره), the final ه is silent and simply represents a short "e" vowel sound. It is pronounced sayyaareh raa, without any "h" sound at the end of the noun.
