sentences:  The origin of the French word is unclear, but probably derives from Spanish "azar" ("an unfortunate card or dice roll"), with the final -d by analogy with the common French suffix "-ard".The Spanish word has been supposed in turn to come from Arabic, either from the name of a castle in Palestine, or from the word "az-zahr" (الزهر) meaning "dice".However, early evidence for this word in Arabic is lacking, as it is absent from Classical Arabic dictionaries, making the etymology doubtful (although any other source is unknown).
