eure

‖ [ Gr. &unr_; I have found, perfect indicative of &unr_; to find. ] The exclamation attributed to Archimedes, who is said to have cried out “Eureka! eureka!” (I have found it! I have found it!), upon suddenly discovering a method of finding out how much the gold of King Hiero's crown had been alloyed. Hence, an expression of triumph concerning a discovery. [ 1913 Webster ]
