'classic-functional' originates from the combination of 'classic,' which comes from Latin 'classicus,' meaning 'belonging to a class or division,' and 'functional,' derived from 'function,' which comes from Latin 'functio,' meaning 'performance or execution.'

'classic' evolved from the Latin 'classicus' through Old French 'classique,' while 'functional' developed from the Latin 'functio' through Middle English 'function.'

Initially, 'classic' referred to something of the highest class, while 'functional' meant related to a function. Over time, 'classic-functional' came to describe something that is both traditionally styled and practically useful.
