"official who calls Muslims to prayer from the minaret of a mosque," 1580s, from Arabic muadhdhin, properly active participle of adhdhana, frequentative of adhanna "he proclaimed," from uthn "ear." Compare Hebrew he'ezin "he gave ear, heard," from ozen "ear." English spelling is from dialectal use of -z- for -dh-.[muezzin etymology, muezzin origin, 英语词源]
