'systematically-assembled' originates from the combination of 'systematic' and 'assemble'. 'Systematic' comes from the Greek word 'systēmatikos', where 'systēma' meant 'organized whole'. 'Assemble' comes from the Latin word 'assemblare', where 'ad-' meant 'to' and 'simulare' meant 'make similar'.

'Systematic' evolved from the Greek 'systēmatikos' through Latin and Old French, while 'assemble' transformed from Latin 'assemblare' through Old French 'assembler', eventually becoming the modern English 'assemble'.

Initially, 'systematic' meant 'pertaining to a system', and 'assemble' meant 'to bring together'. Over time, 'systematically-assembled' evolved to mean 'organized or put together in a methodical manner'.
