'systematically-applied' originates from the combination of 'systematic' and 'applied', where 'systematic' comes from the Greek 'systēmatikos', meaning 'pertaining to a system', and 'applied' is derived from the Latin 'applicare', meaning 'to attach or join'.

'systematic' evolved from the Greek 'systēmatikos' through Latin 'systematicus' and eventually became the modern English word 'systematic'. 'Applied' transformed from the Latin 'applicare' through Old French 'applier' and Middle English 'applien'.

Initially, 'systematic' meant 'pertaining to a system', and 'applied' meant 'to attach or join'. Over time, 'systematically-applied' evolved to mean 'implemented in a methodical manner'.
