Questions & Answers about شاسی بازسازیشده باید گران بوده باشد.
How is the word bazsazi-shode formed, and how does it act as an adjective here?
It comes from the compound verb bazsazi kardan (to restore). To make the passive participle, we take the non-verbal part bazsazi and add shode (the past participle of shodan, to become). It acts just like a regular adjective modifying shasi, connected by an unseen ezafe as shasi-ye bazsazi-shode.
Could I say this using a full relative clause with ke instead?
Yes, you could say shasi-i ke bazsazi shode (the chassis that was restored). However, using the compound passive participle directly as an adjective (shasi-ye bazsazi-shode) is a very common and elegant way to reduce the relative clause, making the sentence more concise.
Why do we use bude bashad instead of a regular past tense for 'must have been'?
The modal word bayad (must) forces the following verb into a subjunctive mood. Because the deduction is about a past state, you need the perfect subjunctive. This is made using the past participle of the main verb (bude) plus the present subjunctive of the auxiliary verb (bashad).
Is shasi a native Farsi word?
No, shasi is a loanword from the French word chassis. Just like in English, it refers to the load-bearing framework of an automobile or machine.
