'sporadically' originates from Greek, specifically the word 'sporadikos,' where 'spora' meant 'scattered.' 'Collected' comes from Latin, specifically the word 'collectus,' where 'col-' meant 'together' and 'legere' meant 'to gather.'

'sporadically' changed from the Greek word 'sporadikos' and eventually became the modern English word 'sporadic.' 'Collected' transformed from the Latin word 'collectus' and became the modern English word 'collect.'

Initially, 'sporadically' meant 'scattered or dispersed,' but over time it evolved into its current meaning of 'occurring at irregular intervals.' 'Collected' has largely retained its original meaning of 'gathered together.'
