eureka (English)
Where does "eureka" come from?
The English exclamation 'eureka' derives from the Ancient Greek 'heúrēka', meaning 'I have found'[1]. This form is the perfect active indicative first person singular of the verb 'heurískō', meaning 'to find'[1]. According to tradition, Archimedes famously shouted the word upon discovering how to measure an object's density[1]. The term first appeared in English around 1603 in the writings of Philemon Holland[1].
