Questions & Answers about اصطکاک چرخدندهها را فرسوده میکند.
The plural word چرخدندهها (gears) is in this sentence. Is this an example of an inanimate plural taking a singular verb?
Not exactly, but it is easy to mix up! Here, the subject doing the action is the singular word اصطکاک (friction), which is why the verb is singular. However, if the gears were the subject (for example, 'The gears wear out'), you would still use a 3rd-person singular verb because inanimate plural subjects take singular verbs in Farsi.
How does the compound verb فرسوده میکند work here?
It is made of the adjective فرسوده (worn out or decayed) and the verb میکند (it makes or does). Literally, the sentence says friction 'makes worn out' the gears.
What are the root words inside چرخدندهها?
It is a compound noun made of چرخ (wheel) and دنده (tooth or rib), followed by the plural suffix ها. So a 'tooth-wheel' translates to a gear.
Does the specific object marker را always come after the plural suffix ها?
Yes! When a noun is both plural and a specific direct object, the plural suffix ها attaches directly to the noun first, and then the marker را follows it, just as we see in چرخدندهها را.
