Unhook → It is formed from "un-" (meaning not or opposite of) and "hook" (from Old English "hoc", meaning a curved or bent instrument). The word "unhook" means to remove or detach something that is hooked or fastened.
Think of 'un-' meaning not or the opposite, and 'hook' as something that is fastened. So, unhook means to take something off that is fastened.
