'sporadically' originates from Greek, specifically the word 'sporadikós,' where 'spora' meant 'scattered.' 'Move' originates from Latin, specifically the word 'movere,' meaning 'to move.'

'sporadikós' transformed into the Medieval Latin word 'sporadicus,' and eventually became the modern English word 'sporadic.' 'Movere' transformed into the Old French word 'movoir,' and eventually became the modern English word 'move.'

Initially, 'sporadic' meant 'scattered or dispersed,' and 'move' meant 'to change position.' Over time, 'sporadically-moved' evolved to mean 'moved in an irregular manner.'
