adjective shockingly repellent; inspiring horror
originBorrowed from French macabre, whose etymology is uncertain. Possibly from the term danse macabre, most commonly believed to be from corruption of the biblical name Maccabees; compare Latin Chorea Machabaeorum. Another theory derives the French term (through Spanish macabro) from Arabic مَقَابِر (maqābir, “cemeteries”), plural of مَقْبَرَة (maqbara) or مَقْبُرَة (maqbura).
