Some adjectives are non-gradable. For example, something can't be a bit finished or very finished. You can't be a bit dead or very dead. These adjectives describe absolute qualities. To make them stronger we have to use modifiers like absolutely, totally or completely:

Their farm was totally destroyed by a tornado.
My work is completely finished. Now I can relax.
