Eureka, California
"Eureka" received its name from a Greek word meaning "I have found it!" This exuberant statement of successful (or hopeful) gold rush miners is also the official motto of the State of California. Eureka is the only U.S. location to use the same seal as the state for its seal.
Hallaca
According to Adolfo Ernst, the word "hallaca" evolved from the indigenous Guarani language, stemming from the verb "ayua" or "ayuar", meaning "to mix or blend". From there, the construction "ayuaca" (mixed things) devolved to "ayaca" and ultimately to "hayaca" or "hallaca" (using Spanish silent "h" when written). Another version presumes that the word comes from an aboriginal language of the West of the country, whose meaning is "wrapping" or "bojote".The earliest use of the word in the modern sense is in a 1781 document of Italian missionary linguist Filippo Salvatore Gilii.
