Questions & Answers about Le enviaré el documento a mi profesora mañana.
Because le is the indirect object pronoun, and in Spanish it is very common to repeat the indirect object this way.
- le = to her / to him / to you (formal)
- a mi profesora makes it clear who that le refers to
So Spanish often uses both:
This is not considered redundant in the way it often would be in English. In Spanish, it sounds natural.
Here, le means to her.
In this sentence:
- el documento = the thing being sent → the direct object
- mi profesora = the person receiving it → the indirect object
So:
- le = to her
- enviaré = I will send
Together:
- Le enviaré... = I will send her... / I will send to her...
