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.
Etruscan civilization
No etymology exists for "Rasna", the Etruscans' name for themselves. The etymology of "Tusci" is based on a beneficiary phrase in the third Iguvine tablet, which is a major source for the Umbrian language. The phrase is "turskum ... nomen", "the Tuscan name", from which a root *Tursci can be reconstructed. A metathesis and a word-initial epenthesis produce "E-trus-ci". A common hypothesis is that *Turs- along with Latin "turris", "tower", come from Greek , "tower." The Tusci were therefore the "people who build towers" or "the tower builders." This venerable etymology is at least as old as Dionysius of Halicarnassus, who said "And there is no reason that the Greeks should not have called them by this name, both from their living in towers and from the name of one of their rulers."
