c. 1600, "a flourish sounded on a trumpet or bugle," from French fanfare "a sounding of trumpets" (16c.), from fanfarer "blow a fanfare" (16c.), perhaps echoic, or perhaps borrowed (with Spanish fanfarron "braggart," and Italian fanfano "babbler") from Arabic farfar "chatterer," of imitative origin. French fanfaron also came into English 1670s with a sense "boastful."[fanfare etymology, fanfare origin, 英语词源]
