a problem with "a" using by some verbs
Hi. please pay attention to these two sentences: Ella presenta el mono. Ella presenta a su primo. According to these two sentences: when do we use "a" after a verb like "presenta" and when don't we use it? i have a great problem with using or not using "a" after some verbs such as "culpa". "presenta", "visita" and so on. please let me know. thanks
There is something called the 'personal a' which is thrown in before a human which is the direct object such as: Vi a su amigo (or hermana, madre etc.) which means I've seen your friend. Vi una casa = I've seen a house (not a person). There are also some verbs which need an 'a' after it anyway. I have tried to list them all in a document but I have included 'de' too. Perhaps it may be of some use to you: http://spanishplus.tripod.com/VerbsandPrepositions.htm#TopOfPage
My Spanish teacher explained it as "whenever the verb is being done/involves someone else, use the 'a'." You visit a person, blame a person, introduce a person, etc.
However, with the monkey and the cousin sentences, there's probably something more subtle going on. "Presentar" can mean "to introduce" AND "to show." Is she showing the monkey--like show and tell--and introducing the cousin to the group? If yes, then there's an object noun missing.
