Questions & Answers about مهندس فولاد را انتخاب کرد، زیرا فولاد قوی است.
Why do we use the normal present tense است after زیرا instead of the subjunctive?
زیرا means 'because' and introduces a factual reason. When you are stating a real, established fact like steel being strong, you use the normal indicative tense. The subjunctive is saved for things like doubts, wishes, or possibilities.
Could I use چون instead of زیرا in this sentence?
Yes! Both mean 'because'. زیرا is slightly more formal and often used in writing, like in this sentence. چون is more casual and is what you will hear most often in everyday conversation.
Why does فولاد (steel) take را in the first half of the sentence, but not in the second half?
The word را marks a definite direct object. In the first half, steel is the object receiving the action because it is what the engineer chose. In the second half, steel is the subject of its own clause (steel is strong), and subjects never take را.
How does the verb انتخاب کرد work here?
This is a compound verb. انتخاب means 'choice' or 'selection', and کرد is the simple past tense of 'to do'. So literally, the engineer 'did a selection' of the steel. This is how Farsi forms many of its verbs!
