Preposition + qui/què
Qui and Què After Prepositions
After a preposition, qui refers to people and accented què to things.
How It Works
El tema de què parlem contains de because parlar governs de. El projecte en què participem contains en because participar takes en. Què bears an accent in these prepositional relative uses and does not vary with the antecedent.
Compare human and nonhuman antecedents without changing the governing relation: la persona amb qui col·laboro and el projecte en què participo. A longer agreeing form can replace either when suitable, but qui and què remain invariant. The accent on què distinguishes it from unstressed que, not from a hypothetical plural. Choose the preposition by reconstructing the embedded phrase before replacing it with a relative.

I do not understand the reason why they reject it.

Keep the preposition licensed by the relative’s embedded function. Build a personal free or prepositional relative with qui.
