'systematically-built' originates from the combination of 'systematic' and 'built'. 'Systematic' comes from the Greek word 'systēmatikos', where 'systēma' meant 'organized whole'. 'Built' is the past participle of 'build', which comes from the Old English 'byldan', meaning 'to construct'.

'Systematic' evolved from the Greek 'systēmatikos' through Latin 'systematicus' and eventually became the modern English word 'systematic'. 'Built' evolved from the Old English 'byldan' to the modern English 'build'.

Initially, 'systematic' meant 'pertaining to a system', and 'built' meant 'constructed'. Together, they evolved to mean 'constructed in a methodical manner'.
