'eureka' originates from Ancient Greek, specifically the word 'εὕρηκα' (heurēka), where 'εὑρίσκω' (heuriskō) meant 'I find.'

'εὕρηκα' transformed into the Latin word 'eureka,' and eventually became the modern English word 'eureka.'

Initially, it meant 'I have found it,' and this meaning has largely remained the same in modern usage.
