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.
Names of Germany
Also the Italian for "German", "tedesco" (local or archaic variants: "todesco", "tudesco", "todisco"), comes from the same Old High German root, although not the name for "Germany" ("Germania"). Also in the standardised Romansh language "Germania" is the normal name for Germany but in Sursilvan, Sutsilvan and Surmiran it is commonly referred to as "Tiaratudestga", "Tearatudestga" and "Tera tudestga" respectively, with "tiara/teara/tera" meaning "land". French words "thiois", "tudesque", "théotisque" and "Thiogne" and Spanish "tudesco" share this etymology.
