Questions & Answers about Ahora le devolvemos la llamada.
What does the pronoun in le devolvemos refer to?
Le is the indirect object pronoun meaning “to him/her/you-formal (usted)” in singular. It refers to the person who will receive the returned call. Without more context, it’s ambiguous which of those three.
Why is it le and not lo or la?
Because with devolver, the pattern is devolver algo a alguien (return something to someone). Here, la llamada is the direct object (the thing returned), and the person is the indirect object, so le is correct. Using lo/la would wrongly point to the call as a direct object pronoun.
When would I use les instead of le?
Is this an example of Spanish leísmo?
No. Here le is an indirect object, which is standard everywhere. Leísmo is using le as a direct object for people (e.g., in Spain many say Le llamo instead of Lo llamo). With devolver la llamada a alguien, the person is an indirect object, so there’s no leísmo.
