It is the formal plural form of the verb "aimer" (to like). It is used when addressing multiple people formally, or when addressing one person formally (for example, a stranger or someone in a position of authority).
Here are some examples of how to use "vous aimez":
* "Vous aimez le chocolat?" (Do you like chocolate?)
* "Oui, nous aimons beaucoup le chocolat." (Yes, we like chocolate very much.)
* "Vous aimez le cinéma?" (Do you like movies?)
* "Oui, j'aime beaucoup aller au cinéma." (Yes, I like to go to the movies a lot.)
Remember that "vous" can be both singular and plural in formal French. So, when talking to one person formally, you would still use "vous" and "aimez".
