'sporadically' originates from Greek, specifically the word 'sporadikos,' where 'spora' meant 'scattered.' 'Assembled' comes from Old French 'assembler,' meaning 'to bring together.'

'Sporadically' evolved from the Greek 'sporadikos' to the Late Latin 'sporadicus,' and eventually became the modern English 'sporadically.' 'Assembled' transformed from the Old French 'assembler' to the Middle English 'assemble,' and eventually became the modern English 'assembled.'

Initially, 'sporadically' meant 'scattered or dispersed,' and 'assembled' meant 'brought together.' Over time, 'sporadically-assembled' evolved to mean 'put together in an irregular manner.'
