It's a more direct and forceful way of telling someone to leave than "S'il vous plaît, partez."
Here's a breakdown of the phrase:
* Allez: This is the imperative form of the verb "aller" (to go).
* Vous: This is the formal pronoun "you."
* En: This means "away" or "out."
So, "Allez vous en" literally translates to "Go you away," but it's better understood as a more emphatic "Get out!"
Important note: While this phrase can be used in situations where you need someone to leave, it's important to use it appropriately. It can be considered rude or aggressive depending on the context and your relationship with the person you're speaking to.
