How to use "s'en aller" in French

s'en aller  in the Present tense (Le Présent)

s'en aller  as an imperative (L'Impératif)

You can use it to tell people to go away:

If you want to understand the structure (you don't have to but it's interesting), the en part is actually a replacement (pronoun) for an unspoken d'ici or de [place] so it means from here or from [place].

So,
