eureka (English)
Where does "eureka" come from?
The English exclamation "eureka" comes directly from the Ancient Greek word "heurēka," meaning "I have found." It is famously associated with the polymath Archimedes, who allegedly shouted it upon discovering a method to determine an object's density. The word entered the English language around 1603 as a way to express the joy of a sudden, brilliant realization.
