Unleash → It is formed from "un-" (meaning not or opposite of) and "leash" (from Old English "leas", meaning to bind or restrain). The word "unleash" means to remove the restraint or binding, allowing something to be free or to act without limitation.
Think of 'removing a restraint' ('un-') from something that is 'bound' ('leash') — that's why unleash means to set free.
