Etymologically, an assassin is an "eater or smoker of hashish," from Arabic hasisi. During the Crusades, there was a sect of Muslim fanatics who, under the influence of hashish, killed Christians and other enemies. In Arabic, they were called hashshashin, "hashish eaters." In English, this plural form was perceived as singular assassin, "one who kills a public figure for political or religious rather than personal motives." The verb assassinate is from the Medieval Latin verb assassinare, "to kill."
