vous meaning plural
how is vous used when it means a plural you? does it use the same verb conjugations and then how do you know if it is a singular or plural you?
Verbs conjugated with "vous" are always *second person plural. The individual verb endings depend on the verb, but a lot are similar. Here's a verb conjugator table for you to explore.... http://french.about.com/library/verb/bl-verbconjugator.htm If the verb you are looking for isn't there, then use the Google machine.
As for knowing if "vous" is singular or plural, it doesn't change the verb endings, but to know if it is talking about 1 person formally, or many people (formally or informally) all depends on context (see Sitesurf's comment below).
