'idolize' originates from the Greek word 'eidolon,' meaning 'image' or 'idol.'

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

Initially, it meant 'to worship an idol,' but over time it evolved into its current meaning of 'to admire excessively.'
