'cylindrical' originates from the Greek word 'kylindros', where 'kylindros' meant 'roller' or 'cylinder'.

'kylindros' transformed into the Latin word 'cylindrus', and eventually became the modern English word 'cylinder' and its adjective form 'cylindrical'.

Initially, it meant 'roller' or 'cylinder', and over time it evolved into its current meaning of 'having the shape of a cylinder'.
