'rhetorician' originates from the Latin word 'rhetorica', which in turn comes from the Greek word 'rhētorikē', where 'rhētōr' meant 'speaker'.

'rhētorikē' transformed into the Latin word 'rhetorica', and eventually became the modern English word 'rhetorician'.

Initially, it meant 'a speaker or orator', but over time it evolved into its current meaning of 'a person skilled in rhetoric'.
