Questions & Answers about Podes enviar-me o ficheiro da apresentação?
Why is me attached to the end of enviar with a hyphen?
In Portuguese, when you have a conjugated verb (Podes) followed by an infinitive (enviar), you have a choice. The object pronoun (me) can attach to the end of the infinitive with a hyphen, which is what we see here. You could also place it before the conjugated verb (me podes enviar), but attaching it to the infinitive is very common and natural in Portugal.
Is me a direct or indirect object pronoun in this sentence?
It is an indirect object pronoun meaning "to me". The direct object (the thing actually being sent) is o ficheiro (the file). Because you are sending the file TO someone, that person (me) is the indirect object. The pronoun form for both direct and indirect is me, but its role here is indirect.
Why does the sentence use da apresentação instead of just de apresentação?
da is a contraction of the preposition de (of) and the feminine definite article a (the). We use it because we are talking about a specific presentation ("the file of the presentation"). If we just said de apresentação, it would sound like a general "presentation file" without a specific presentation in mind, but Portuguese prefers being specific here.
How do we know it means "Can you send" when there is no word for "you" in the sentence?
