'sporadically' originates from Greek, specifically the word 'sporadikos,' where 'spora' meant 'scattered.' 'Implemented' comes from Latin, specifically the word 'implementum,' where 'implere' meant 'to fill up.'

'sporadically' changed from the Greek word 'sporadikos' and eventually became the modern English word 'sporadic.' 'Implemented' evolved from the Latin 'implementum' through Old French 'implementer.'

Initially, 'sporadic' meant 'scattered or dispersed,' and 'implement' meant 'to fill up or complete.' Over time, 'sporadically-implemented' evolved to mean 'irregularly executed.'
