'Vos' versus. 'vosotros' I say 'vos' may be the just like 'tu'--informal and single and 'vosotros' may be the casual dual form (most Spanish nations use 'ustedes ~'~~) Therefore, for instance, como estas vos could make sense...as properly as como estais vosotros...but perhaps not como estas vosotros o-r como estais vos...right? What's the foundation of 'vos'? Exactly why is 'vosotros' not in keeping use? Wish this line is sensible.
