Eureka (word)
"Eureka" comes from the Ancient Greek word "heúrēka", meaning "I found (it)", which is the first person singular perfect indicative active of the verb "heuriskō" "I find". It is closely related to heuristic, which refers to experience-based techniques for problem solving, learning, and discovery.
Eruca sativa
The English common name "rocket" derives from the French "roquette", a diminutive of the Latin word "eruca", which once designated a particular plant in the family Brassicaceae (probably a type of cabbage). "Arugula" (), the common name now widespread in the United States and Canada, entered American English from a non-standard dialect of Italian. The standard Italian word is "rucola", a diminutive of the Latin "eruca". The "Oxford English Dictionary" dates the first appearance of "arugula" in American English to a 1960 article in "The New York Times" by food editor and prolific cookbook writer Craig Claiborne.
