What's the difference between recover and re-cover?

That little hysterical hyphen is a hyper hypnotist in that it can completely hype a word. Recover means “to get well, heal”. Re-cover means “to put on a new cover”. Same with remark and re-mark; remark means “to say something”; re-mark means “to mark it again”. Got it? Take care in using the re-words. (Okay reword means “to word it again”; that’s all!)
