Enslave → It is formed from "en-" (meaning to cause to be) and "slave" (from Old French *esclave*, meaning a person who is owned by another). The word "enslave" means to cause someone to become a slave or to make someone a servant against their will.
Think of 'causing someone to be' ('en-') a 'slave' — that's why enslave means to make someone a slave.
