Learn Farsi: این قدرت بی‌رقیب با موتور پیشرفته تولید می‌شود. - This unrivaled power is produced by the advanced motor.

While this lesson focuses on the -ترین suffix to show absolute limits, بی‌رقیب (made of بی‌, meaning "without", and رقیب, meaning "rival") achieves a similar effect inherently. Translating to "unrivaled," it establishes an absolute extreme without needing a superlative grammar structure.

Why is با used here for "by" instead of a word like توسط?

In Farsi passive sentences, با is often used when the action is performed by an instrument, tool, or machine (like the موتور here). توسط (by) is typically reserved for conscious, human agents.

What kind of word is پیشرفته and how is it formed?

It is a past participle functioning as an adjective, meaning "advanced." It is formed from the compound verb پیش رفتن (to go forward / to progress) by taking the past stem (پیش رفت) and adding ه.

How does the passive voice work in the verb تولید می‌شود?

For compound verbs that use کردن (to do/make) in the active voice, such as تولید کردن (to produce), you form the passive by swapping کردن with شدن (to become). Thus, تولید می‌شود literally translates to "becomes produced."
