'pedal' originates from Latin, specifically the word 'pedalis,' where 'ped-' meant 'foot.' 'Operate' originates from Latin, specifically the word 'operari,' meaning 'to work.'

'pedal' changed from the Latin word 'pedalis' and eventually became the modern English word 'pedal.' 'Operate' transformed from the Latin 'operari' to the modern English 'operate.'

Initially, 'pedal' meant 'related to the foot,' and 'operate' meant 'to work.' Over time, 'pedal-operated' evolved to mean 'controlled by a pedal.'
