Questions & Answers about ما مدرکی مبنی بر اینکه ماشینتحریر به صورت مکانیکی کار میکند، داریم.
The sentence uses "be surat-e mekâniki" for "mechanically". Could I use "be tor-e mekâniki" here instead?
Yes, you can. Both be surat-e (literally "in the form of") and be tor-e (literally "in the way of") are used with adjectives to create adverbs. be surat-e mekâniki and be tor-e mekâniki are practically interchangeable here, though be surat-e is often preferred when describing the physical "form" or "state" in which a machine operates.
What exactly does "mabni bar" mean, and how is it used with "inke"?
mabni bar is a formal phrase meaning "based on" or "indicating". When you want to follow it with a full clause (like "the typewriter works mechanically"), you must add inke (this that) to act as a grammatical bridge. So mabni bar inke translates smoothly to "indicating that" or "to the effect that".
Why is the main verb "dârim" placed at the very end of the sentence, separated by a comma?
The core of this sentence is simply mâ madraki dârim (We have a proof). The phrase mabni bar inke and the entire sub-clause that follows it act as a giant modifier for the noun madraki. Because Farsi is generally Subject-Object-Verb, the main verb dârim waits at the very end. The comma helps visually separate that long descriptive block from the final verb.
What does the "-i" suffix on "madraki" do in this context?
The -i suffix makes the noun indefinite, changing madrak (proof/document) to madraki (a proof / some proof). It signals that they have a piece of evidence, which the rest of the sentence is about to describe.
