Questions & Answers about Les respondemos la pregunta a ellas.
Why do we have both 'les' and 'a ellas' in this sentence? Isn't that saying 'to them' twice?
Yes, it is! In Spanish, it is completely normal and often required to use the indirect object pronoun (les) even when you specifically name the people receiving the action (a ellas). The les tells us the action is happening to or for someone, and a ellas clarifies exactly who that is.
Since it is 'ellas' (feminine), why do we use 'les' instead of 'las'?
Could we just say 'Respondemos la pregunta a ellas' and leave out 'les'?
No, that would sound very unnatural in Spanish. With verbs of communication like responder (to answer), when you name the indirect object at the end (a ellas), the pronoun before the verb (les) is grammatically required to match it.
Is the word 'a' always required before 'ellas' here?
Yes. When you spell out the indirect object to clarify exactly who is receiving the message, you must use the preposition a. Think of a ellas as meaning 'to them' or 'for them' in this context.
