'systematically-selected' originates from the combination of 'systematic' and 'select,' where 'systematic' comes from the Greek 'systēmatikos,' meaning 'organized,' and 'select' from the Latin 'selectus,' meaning 'chosen.'

'systematic' evolved from the Greek 'systēmatikos' through Latin and Old French, while 'select' transformed from the Latin 'selectus' through Old French 'selecter,' eventually becoming the modern English 'select.'

Initially, 'systematic' meant 'pertaining to a system,' and 'select' meant 'to choose.' Over time, 'systematically-selected' evolved to mean 'chosen in an organized manner.'
