prestidigitator (n.)
1843, from French prestidigitateur, a hybrid coined 1830 by Jules de Rovère (who sought a new word, "qui s'accorderait mieux à ses nobles origines" to replace escamoteur and physicien), roughly based on Latin praestigiator "juggler" (see prestigious); influenced by Italian presto "quick," a conjuror's word (see presto), and by Latin digitus "finger" (see digit).
