"Enervate" is a word that some people use without really knowing what it means. They seem to believe that because "enervate" looks a little bit like "energize" and "invigorate" it must share their meaning -- but it is actually their antonym. "Enervate" comes from the Latin word "enervare," which was formed from the prefix "e-," meaning "out of," and "-nervare" (from "nervus," meaning "sinew or nerve"). So, etymologically at least, someone who is enervated is "out of nerve."
