'skeptic' originates from the Greek word 'skeptikos,' where 'skeptikos' meant 'inquirer' or 'doubter.'

'skeptikos' transformed into the Latin word 'scepticus,' and eventually became the modern English word 'skeptic' through Middle English.

Initially, it meant 'inquirer' or 'doubter,' but over time it evolved into its current meaning of 'a person inclined to question or doubt accepted opinions.'
