Learn Farsi: هر چه که شما بسازید، این دستگاه پیشرفته به مراتب سودآورتر است. - Whatever you build, this advanced machine is by far more profitable.

Be marâteb translates to "by far" or "considerably." In Farsi, when you want to intensify a comparative adjective (like sudâvartar, meaning "more profitable"), you place be marâteb before it. So, be marâteb sudâvartar means "by far more profitable."

Why is the verb besâzid (you build) in the subjunctive mood?

We use the subjunctive here because the phrase har che ke (whatever) creates a hypothetical or uncertain condition. You aren't talking about a specific thing they have already built, but rather anything they might build. Therefore, the verb takes the subjunctive prefix be-.

How is the word sudâvartar (more profitable) constructed?

It is made of three parts: sud (profit) + âvar (the present stem of âvardan, meaning "to bring") + tar (the comparative suffix "-er" or "more"). Literally, it translates to "more profit-bringing."

Is the ke in har che ke (whatever) required?

In conversational Farsi, you can often drop the ke and just say har che shomâ besâzid (or even use har chi in spoken language). Adding ke makes it sound a bit more complete and formal, which matches the slightly formal tone of this specific sentence.
