Weakened → It is formed from "weak" (from Old English *wac, meaning not strong) and "-en" (a suffix used to form verbs indicating to make or become). The word "weakened" means to have made something less strong or to have become less strong.
Think of something that has become 'not strong' ('weak') and then 'made' ('-en') even less strong — that's what weakened means.
