when/where is the "vosotros" form used?
my teacher said it really isn't necessary to learn the "vosotros" form so i'm wondering about this. any suggestions?
My short unenlightened answer is
In Spain and it is second person plural.
As far as I know in Latin countries they use third person plural instead. (Ustedes form, if you prefer...).
in spain only all the other countries use ustedes. you use it in second person plural.
It depends where your from. In Spain they use vosotros. It means you all. How are you (tu)? = Cmo estás? How are you (vosotros)? = Como estaís?
In Latin America I'm sure that they don't use vosotros much, if atall. Instead they just use 'They' Como estan? quien son? etc
So, IF you use it, use it to say 'you all', 'you both'
It's used mostly in Spain. To completely ignore the form would be foolish as you will need to recognize and use it at some point. He/she may not be the only Spanish teacher that you ever have. You could give it a lower priority than learning the other forms, however. I actually think ignoring it would be harder than learning it. You're going to have problems when learning rules that concern 2nd person, informal, 2nd person formal and 3rd person if you don't know what they are talking about every time the discuss 2nd person informal , plural (vosotros) or use the os pronoun, etc.
