'systematically-sent' originates from the combination of 'systematic' and 'sent', where 'systematic' is derived from the Greek word 'systēmatikos', meaning 'pertaining to a system', and 'sent' is the past participle of 'send', from Old English 'sendan'.

'systematic' evolved from the Greek 'systēmatikos' through Latin 'systematicus', and 'sent' from Old English 'sendan', eventually forming the modern English compound 'systematically-sent'.

Initially, 'systematic' meant 'pertaining to a system', and 'sent' meant 'dispatched'. Together, they evolved to mean 'dispatched in an organized manner'.
