Questions & Answers about مراقبت کردن از این سگ بیمار به تعهد زیادی نیاز دارد.
Why is the full infinitive مراقبت کردن used at the beginning of the sentence?
In Farsi, you can use the full infinitive to act as the subject of a sentence, exactly like a gerund (an '-ing' noun) in English. Here, مراقبت کردن simply translates to 'caring' or 'to care'.
Why do we use the preposition از after the word for 'caring'?
The compound verb مراقبت کردن (to care for / to look after) requires the preposition از. While English uses 'for', Farsi requires you to say you care 'from' someone or something.
Why is there a به before تعهد (commitment)?
This is linked to the verb at the very end of the sentence. The phrase for 'to need' or 'to require' is نیاز داشتن, and the thing that is needed must be preceded by the preposition به (to). Literally, the sentence says that caring for the dog 'has a need to' a lot of commitment.
Why does the word for 'a lot' have a ی at the end in تعهد زیادی?
While you could just say تعهد زیاد using the base word for 'a lot', adding the ی suffix to make زیادی is a very common way to emphasize a large quantity or high degree when describing an uncountable noun like commitment.
