Prepositional relative clauses (dar ân, bâ u)

Prepositions in Relative Clauses

In the previous lesson, we learned that Farsi uses a "resumptive pronoun" to refer back to a noun inside a relative clause. This rule also applies when the noun is the object of a preposition (like in, with, or at).

In English, we often leave prepositions at the end of the clause ("the aquarium that the sharks live in"). In Farsi, you must keep the preposition inside the relative clause and pair it with a pronoun: آن for things and animals, or او for people.

You are literally saying "the aquarium that the sharks live in it" (در آن).

Other Prepositions

This structure works seamlessly with any preposition, whether it is a simple word like از (from) or a compound preposition like درباره‌ی (about) or زیر (under).

Objects in Both Clauses

Sometimes, the noun is the direct object of the main sentence, while simultaneously acting as the object of a preposition inside the relative clause.

When this happens, the main noun still takes the direct object marker را right before که. Inside the relative clause, nothing changes: you still use the preposition followed by آن or او.
