Show wordsHide wordsMore about this word part:
The prefix re- occurs in verbs that are Latin loanwords, where it can mean "again" (revise ) or "back again" (reflect ). It also attaches to English verbs (replay , rewind) with both meanings. Any verb can be prefixed by "re- " to indicate that an action is repeated. No hyphen is necessary unless the word formed is identical to an existing word (re-sign the document, but resign from a job).
