Learn Farsi: دلبستگی متقابل در قبال مربی رشد می‌کند. - Mutual attachment grows towards the trainer.

While nesbat be just indicates a general direction or feeling, dar qebâl-e carries a subtle sense of reciprocal relationship, duty, or response. Because the attachment is motaqâbel (mutual), using dar qebâl-e emphasizes that this feeling exists in relation to or as a direct response to the trainer's role and efforts.

How does the word motaqâbel relate to the lesson's theme of reciprocal duty?

The word motaqâbel means "mutual" or "reciprocal." It comes from an Arabic root implying two parties facing or interacting with each other, which conceptually reinforces the meaning of qebâl. It pairs perfectly with dar qebâl-e to show that the attachment is a shared, two-way dynamic rather than a one-sided feeling.

Is delbastegi used for physical attachment or emotional attachment?

It is strictly emotional. It literally translates to "heart-tied-ness" from del (heart) and bastegi (attachment or dependence). It means affection or devotion. For physical attachment or connecting objects together, you would use entirely different vocabulary.

Can roshd kardan (to grow) be used for abstract feelings in Farsi?

Yes, exactly like in English. While roshd kardan is used for the physical growth of plants or children, it is perfectly natural to use it metaphorically for relationships, emotions, or even economies developing and getting stronger over time.
