Usted/Ustedes<o:p></o:p>
This is a way of speaking formally to someone, for example an older person or teacher.<o:p></o:p>
For the 2nd person, use the 3rd person ending.<o:p></o:p>
For the 2nd person plural, use the 3rd person plural ending.<o:p></o:p>
E.g.<o:p></o:p>
-To say 'you talk quickly' to one friend: 'hablas rápidamente'.<o:p></o:p>
-To say 'you talk quickly' to one teacher: 'habla rápidamente'.<o:p></o:p>
-To say 'you talk quickly' to two friends: 'habláis rápidamente'.<o:p></o:p>
-To say 'you talk quickly' to two teachers: 'hablan rápidamente'.<o:p></o:p>
'You plural'<o:p></o:p>
Just remember that if you're saying something directed at more than one person, you need to use the 'vosotros', or 2nd person plural form.<o:p></o:p>
