I have a two part question:
1) My sentence is
>I escape the lion.

Do I say
>Je èchappe le lion

 or
>Je s'echapper du lion

 or neither?

2) I see other verbs that are otherwise identical but one will have a *s'* before them. My grammar book does not explain what the purpose of the *s'* is. Could someone explain this to me or direct me to a resource online?
