In most of Latin America, the "ustedes" form is used instead.
Here's how to conjugate a verb in the second person plural:
Spain:
* Vosotros + verb ending in -áis (for regular -ar verbs)
* Vosotros + verb ending in -éis (for regular -er verbs)
* Vosotros + verb ending in -ís (for regular -ir verbs)
Latin America:
* Ustedes + verb ending in -an (for regular -ar verbs)
* Ustedes + verb ending in -en (for regular -er verbs)
* Ustedes + verb ending in -en (for regular -ir verbs)
Example:
* Spain: Vosotros habéis comido. (You all have eaten)
* Latin America: Ustedes han comido. (You all have eaten)
It's important to understand the context to use the correct form!
