Questions & Answers about هر قدر هم که کار کند، این پوشش ضد سایش از خش جلوگیری می‌کند.

How exactly does ضد سایش work here to mean "anti-wear"?
The word ضد means "anti," "counter," or "against." To form a compound adjective or noun describing opposition, you link ضد to a noun using the ezafe vowel (an unseen "e" sound). Here, سایش means "wear" or "friction," so ضد سایش becomes "anti-wear." Because it acts as an adjective for پوشش (coating), they are also linked by ezafe: پوششِ ضدِ سایش (pushesh-e zedd-e sâyesh).
Why is the verb کند in the subjunctive form after هر قدر هم که?
The phrase هر قدر هم که translates to "no matter how much" or "however much." In Farsi, phrases expressing "no matter [question word]" introduce a hypothetical or indefinite situation, which requires the verb in the dependent clause to be in the subjunctive mood. That is why we see کار کند (works) instead of the indicative کار می‌کند.
Does the verb جلوگیری می‌کند always take the preposition از?
Yes! The compound verb جلوگیری کردن means "to prevent" or "to stop." In Farsi, you prevent from something, so it almost always pairs with the preposition از. Here, از خش جلوگیری می‌کند literally translates to "prevents from scratches."
Is سایش related to a specific verb?
Yes, سایش (wear or friction) is a noun derived from the present stem of the verb ساییدن (to rub, grind, or wear away). In Farsi, adding the suffix ـِش (-esh) to a verb's present stem is a very common way to create a noun of action or state.
