'systematically-sectioned' originates from the combination of 'systematic' and 'sectioned', where 'systematic' comes from the Greek word 'systēmatikos', meaning 'pertaining to a system', and 'sectioned' from the Latin 'sectio', meaning 'a cutting'.

'systematic' evolved from the Greek 'systēmatikos' through Latin 'systematicus', and 'sectioned' from Latin 'sectio' through Old French 'section'.

Initially, 'systematic' meant 'pertaining to a system', and 'sectioned' meant 'a cutting'. Over time, they combined to describe something divided in an organized manner.
