mistake?

Uds vivian en Puerto Rico why you used to live in Puerto Rico when uds vivian are plural just asking.

In English the "you" is used to describe one person or more than one. In Spanish we have 2 words for those "you" we use in english...."Tu" (or the polite one usted) and "Ustedes"... Ustedes vivian en Puerto Rico....You (more than one) used to live in Puerto Rico... Tu vivias en Puerto Rico...You (only one person) used to live in Puerto Rico... got it?.... Now with the verb "vivir"...since we are talking in a past tense, you need to say ...."vivias" or "vivian", as you can see in the examples above, the "vivias" is for singular and the "vivian" is for plural form of "you"...USTEDES ;) Mucha suerte con tu curso de Español, si tienes alguna otra duda, hazmelo saber....Good luck with you Spanish course, if you have any other questions, just let me know....saludos ;)
