'systematically' originates from 'system,' which comes from the Greek word 'systēma,' meaning 'organized whole,' and 'collect' from Latin 'colligere,' where 'col-' meant 'together' and 'legere' meant 'to gather.'

'systematically' evolved from the Greek 'systēma' through Latin and Old French, while 'collect' transformed from Latin 'colligere' to Old French 'collecter,' eventually becoming the modern English 'collect.'

Initially, 'systematically' meant 'pertaining to a system,' and 'collect' meant 'to gather together,' which has largely remained the same in modern usage.
