Using the "a" essentially changes the meaning of the verb "ir" to a future tense use. "Vamos" = "We go" is present tense. "Vamos a..." = "We are going..." being expressed as an intention. "We are going to listen" - "Vamos a escuchar". OR you could just go to the studyspanish link as our friend says. Their explanation seems to make better sense than mine! I used their site for some time before trying Duo and it seemed to make learning here easier
I think the issue here is that the direct object of the sentence is you, not my friend.
A direct object answers the question what or who the verb is action on. In this sentence, who is being considered... the answer is you, not my friend.
Since my friend is not a direct object, it doesn't get a 'personal a'.
Does this mean he is going to call him his friend from now on or he is going to consider him for some job? Or is it interchangeable?
So...if i have this correct the lack of the "personal A" shows us that TE is the Direct Object. What if the meaning I was trying to convey was "Im going to consider my friend for you" (as for a job possibly). Would a "personal A" be needed to convey my above example interpretation? And if so does the pronoun TE become an Indirect Object? Hope someone understands my lengthy question. Thanks
