'idol' originates from the Greek word 'eidolon,' where 'eidos' meant 'form' or 'shape.'

'eidolon' transformed into the Latin word 'idolum,' and eventually became the modern English word 'idol' through Old French 'idole.'

Initially, it meant 'an image or representation,' but over time it evolved into its current meaning of 'a person or thing that is greatly admired.'
