Learn Spanish (Latin America): Hay un director para quien trabaja el asistente. - There is a director for whom the assistant works.

In Spanish, when you refer back to a person after a preposition (like para, con, or de), you must use quien (singular) or quienes (plural). Since we are talking about one person (un director), we use quien to mean "whom".

In English, we often say "who the assistant works for." Can I put para at the end of the sentence in Spanish?

No, Spanish never leaves prepositions dangling at the end of a sentence. The preposition (para) must always go right before the relative pronoun (quien). It translates exactly to the formal English structure "for whom".

Why is the verb before the subject (trabaja el asistente) at the end of the sentence?

In Spanish, it is very common and natural to flip the subject and verb in a relative clause, especially after words like que or quien. You could technically say para quien el asistente trabaja, but putting the verb first (trabaja el asistente) flows much better.

Could I use por instead of para in this sentence?
