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.
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.
