4.6 your and your

Ciao Fran,

as you know in Italian the pronoun "you" can be used :

-when addressing to a single person = tu (singular friendly form)
-when addressing to more than one person = voi (plural friendly form)

Same thing happens with the adjectives.

If you are speaking about an object that belongs to the person you are speaking to, you will need to use the adjective "tuo" (or "tua/tuoi/tue" )

Example:

-questa è la tua macchina (this is your car)

If you are speaking about an object that belongs to people you are speaking to, you will need the plural form "vostro" (or "vostra/vostri/vostre")

Example:

-Questa è la vostra macchina

I hope this helps
Buon divertimento con Rocket Italian !!!!
