Reoxidize → It is formed from "re-" (meaning again) and "oxidize" (from Latin "oxydare", meaning to combine with oxygen). The word "reoxidize" means to combine again with oxygen.
Think of 'again' ('re-') and 'combining with oxygen' ('oxidize') — that's why reoxidize means to combine with oxygen again.
